We are going to be going over the, you know,
what’s new in Stratasys 3D printing. It’s been a while since we’ve done one
of these, so there’s a lot to cover in our limited time today. So, we’re going to dive right in, and well,
if you can post any questions in the chat, then I’ll pick them up as they go. So, feel free to type those away, and then
our host here will relay them to me. So, thank you very much, and let’s get started. So, quick overview. We’re going to go through the Stratasys
portfolio, go over their new FDM machine, some of the new tricks on their PolyJet machines,
their new, their little fiber machine, and then if we have any time at the end, we’ll
dive into some of the software updates that have come out. So, diving right in. As most of you might know that we use FDM
process here, Fused Deposition Modeling, that is basically a very precise hot glue gun where
we heat the material and extrude through a head, and put layer upon layer. So, this is a nice little animation that kind
of illustrates that. Moving on. Here is our portfolio of the new… of the
standard FDM portfolio, starting off on our Idea series, which is more of the educational-based
units. Even the uPrint has been used in some production
aspects. Then we get into the Design series. These are the new F123 series as by Stratasys,
and that’s where we’re going to spend the bulk of our time, because we have a new
machine in there. And also, we will be touching base on our
carbon-fiber addition on the 380. So, moving on. So, our production machines, as mentioned,
we have our new, newish machine, the carbon-fiber edition, which was created specifically for
machine shops and places that use a lot of jigs and fixturing. So, this has two material types. It’s the ASA for quick, down, dirty prototypes,
“Let’s get them out onto the floor, test them out.” And then you have the Nylon 12 CF, which is
one of the strongest materials, if not the strongest material that Stratasys offers. So, that one really allows you to build jigs
and fixtures that will take a beating, just like your aluminum stock ones. So, let’s dive into the Stratasys 123 series. So, here we have the new F120 versus the F370
on the right. So, one of the things you’ll notice is that
the F170, 270, and 370 is the same box, but they changed the internal components. So, the outside and the dimensions will stay
the same. It’s just the internal components are what’s
going to change on you. So, taking a closer look at these. So, there you have on the far left, you have
the 120 versus the 170. So, schools, professionals over here on the
far left side. Once again, to the 270 and up, now you’re
talking about a more robust machine, larger build envelope, a little bit more material
choices. You’ve got advanced FDM mode available on
the F170 through the F370 now, and then you also have on the high-end, on the 370, you
have the PC-ABS, which is an ABS plastic with some PC in there, so it gives it that extra
strength and flexibility that people need. Oh, the other big one is the floor material
base, really kicks things off with the auto changeover, right, the 270. So, if you’re doing a lot of large prints,
over-weekend prints, or overnight prints, you’re low on one spool, instead of of having
to take it out, put a new spool in. Now you can have a second spool that can auto-feed
into the head when the first spool runs out. So, you need to deal with less inventory. So, here’s just a quick size comparison. The 370 is much larger than the 170. 10” by 10” by 10” versus 14” by 14”
by 10”. And then, once again, we have four layer resolutions,
except for on the 120. That one only has the 0.007” to the 0.013”. Moving on. Now, what’s new in this? Well, there’s actually 15 new patents that
are pending in application status, and then there’s the 43 patents for the FDM press
that Stratasys is pulling from. So, they are constantly innovating with this
new F series. Inside of here, we have new material options
for both spool-based, so now it’s easier to load, cheaper on the pocketbook, better
quality material, cheaper on the pocketbook. You get a load. You have the great softwares behind it. You have like Insight, if you’re familiar
with the high-end machines, this one allows you to dive into the STL, split it into two
builds if you need to, create groups, layers, and really modify line by line, layer by layer,
tool path by tool path, in STL. You have the GrabCAD Print option, which allows
mobile monitoring, so you can log in from your phone at home over a weekend to check
in on the print, see how it’s building. You can see, you can track a lot of statistics,
who’s printing what, when it’s built, when it’s not, you’ll have Advanced FDM
mode for changing. Think of it as Insight Light and upgraded
user interface, and also, the Soluble Support. Great stuff. So, with that, we have the reason why to go
with one of the F-series is that, well, we have great dimensional accuracy. So, you can see the things right at the top
there, within plus or minus 0.01 inch. So, we have a nice spec of… to be within
spec of. So, that’s one of the best reasons to go
with us. We… Stratasys is really pushing the envelope on
the “Let’s make sure these things are accurate and reliable.” Next, here’s just a list of material. So, you have your engineering-grade on the
left, high performance in the middle, this is when you get into the 450, the 380, regular,
ULTEMs, PPSF, you have your Nylon 12CFs, your Antero, which is the… resistant to oils
and gasolines and such. And then you have your sacrificial tooling
material as well, if you’re doing carbon-fiber layups, but I want to kind of just highlight
a couple of them. First, we’re going to go over the F series,
because we’re spending a lot of time on this F series. It’s a great, great series of machines. You can upgrade from a 170 to a 370 with just
hardware upgrades. So, it’s pretty nice, because you have most
of the box already there. Availability is this will get you through
the bulk of your prototyping and some of your jigs and fixtures needs. So, we know some tool shops that use the PC-ABS
in particular to get their jigs and fixtures off to the races and into production while
the ABS proves out the point. And then, you also have a PLA just like prosumer
printers to really test out ideas in a fast, down-and-dirty way, just “Let’s get a
piece out in someone’s hands quickly and affordably.” TPU is the new flexible, durable one that’s
been a while… it’s been a while. It’s been in the making for quite some time,
but they really honed it in to make sure that when this TPU actually prints, it’s a nice,
high-quality print. Then over here, you’ll see on the left,
F120 versus the F370, the different materials available on each. But to present a different perspective, here’s
all the different colors, because some people really like colors. So, PLA, ABS, and ASAs will have a lot more
color options, as opposed to your TPU. That’s just available in black, where your
PC-ABS has black or white. So, and then also, the little asterisks here
are materials that you can buy in both 60-cubic-inch spools and 90-cubic-inch spools. So, if you’re doing a lot of large prints
over the weekend, you can go to the 90-cubic-inch spools so that you don’t have to go through
it as much or swap out as much. Next, let’s talk about our strongest FDM
material, Nylon 12CF. So, it’s chopped carbon fiber bits inside
of a Nylon 12 as it’s extruded out. So, it is the highest-strength stiffness-to-weight
ratio of any material Stratasys currently offers. And once again, jigs, fixturing, some production
parts, it’s being used to replace some billet aluminum covers and such. Auto trans. Here’s just a layout of its tensile strength
versus others’. XY, PSI, all of these things are looking great. Even the Nylon 12 is doing pretty well. Still not as good as a PC or a Nylon 6, but
then once you get the Nylon 12CF, some of these, you’re three times the… tensile
module is XY, you’re three times the PSI rating. So, it is amazing material, incredibly stiff. And once you put your hands on it and actually
kind of crank on it, you can see the difference and feel it. It’s great. So, I highly recommend when you’re at a
tradeshow or you’re visiting us at one of our upcoming office events in… what was
it—September and October—to get your hands on some carbon fiber and feel it and really
think of the possibilities of this material. The other one is, yes, the new TPU. Yeah, the only elastomer on the market currently
that has that valuable support. So, it’s really easy to print with. You can print it in orientations that seem
counterintuitive. If you’re coming from the persumer world,
so you can print it with the supports and you can get these crisp, great-looking parts
off of it. You can nearly print this part. It looks just like the one on the left, covered
in support material. Then you throw it in the tank and it bops
around for an hour, couple hours, and it comes out crisp, clean, and ready to use. It’s a great way to create very complex
flexible parts. We’re using this new TPU material. So, here’s my other piece, unique geometry,
something that would be hose tie-downs, put into an area that needs to have a flex that
just test out make sure this design works. Really great to do these weird-shaped parts
that before you could do it out of a hard plastic, but it doesn’t truly give you that
feel of wiggling it in place into an engine cavity or like engine bay. Sometimes you just need that flex so that
you can test some things. So, you compare some our TPU versus these
other flexible products that we have or from other competitors. It’s like you can see that our elongation
at break is twice that of our next nearest competitor, down to our ultimate tensile strength
as well is pretty much twice, nearly twice as much as our next competitor as well. So, really show you that this… Stratasys took its time to really get the
key properties of this material correct. And then also with the support material, make
sure that you can print it in geometries that are usable as well. So, it’s really nice in that aspect. Now, let’s get into the PolyJet world. So, watch this little animation here, very
similar to the FDM process, it’s a layer-by-layer process, but this one involves jetting material
from print heads, and then curing with a UV light that allows you to get this crazy, high-definition
parts. One of the trade-offs, just because it looks
good, it’s more brittle, it’s not true thermoplastic, these are acrylic-based polymer. So, here’s our portfolio. Start off at our Objet30, little desktop unit
so you can have it in a cubicle with you, all the way up to the Objet1000, where you
can literally sit on the build tray and you can build small cadavers. But the thing that we’re gonna be focusing
on most here because the biggest advancement that we’ve had are the J750 and the J350. So, let’s get started. So, with the J735 and the J50, the major difference
between the two is build area and the number of materials you can put into your machine. So, longer running, same size containers with
just doubled up on the larger one. So, the process that we normally start off
with is… we happen to be a SOLIDWORKS vendor, so we’re always going to size it up in SOLIDWORKS,
we’re going to model it up in SOLIDWORKS, then you can add stylizing or coloring, creating
a bitmaps that you can then configure and wrap onto your part, and then hit “Print.” So, using a series of different products,
you can do that. I can even use… I personally have used Photoshop, and SOLIDWORKS,
and Tangent together or just use the internal SOLIDWORKS new texturing feature that we did
a great blog post if you check out cati.com about adding texture and color to your prints. So, and that was just using straight-up SOLIDWORKS
2019, and yeah. Then we also have, I believe, a couple blog
posts as well about how to use Photoshop to attach these colors to your SOLIDWORKS model
and you create those bitmaps. So, next, we’re going to start talking about
some photorealistic simulation. Like, we’ve got some crazy great prints
down in the sample world from Stratasys of these amazing parts. We have engineering-grade or the Digital ABS
that we can use to do injection molds or blow molds with, we can do over-molding with a
rubber leg on top of a hard plastic to replicate screwdrivers, other utensils, and then you
can have single color all the way to full-color crazy patterns across your parts, so from
matte to glossy, and then yeah a full spectrum of what’s called the shore values that you
can go from like a nice rubber-like for the sole of your shoe all the way to a hard plastic
that you would normally find in any kitchen utensil you’ve got. So, yeah, J750, it’s one of these large
guys, and it’s the only full-color, multi-material printer on the market right now. So, you can have a rubber leg that has color
in it mixed with a solid plastic. The opportunities with the J750 when you’re
making mock-up products and other such items that require that kind of full-color to really
get a customer buy-in or testing validated, this is the printer for you, because the other
reason is now your graphics/marketing side will be very happy with you. We are the only Pantone-standardized color
system available. So, you can pick out… there’s a nice color
map of the full Pantone color spectrum versus the full visual color spectrum versus what
we can print, so we have gone through with Stratasys and partnered with Pantone to map
out all of the Pantones that this printer can hit. So, if you wanted Coca-Cola red, you can do
that. And then, there’s also the other colors
that don’t quite make it. So, there’s a meter inside of the software
that tells you, “Hey, we’ve detected this color. We can’t actually hit that. We’ll be getting X amount close.” So, then you can go back to your design team
and say, “Hey, this orange is slightly off. If we change it one way or the other, we can
actually get it to print how you want it. Otherwise, it will look a little dull or too
bold.” So, it gives a lot of feedback for when color
isn’t a need, this one will give you all the feedback you’ll need. So, there’s a nice whole family of materials. You can go from the crystal clear so it’s
like glass-looking, all the way down to rubber legs, and Digital ABS, or those really rigid
applications, blow molding like I mentioned before, snap fits and such. And then the Agilus material, which should
be coming up… a couple more slides before I get to Agilus. But yeah, we have a lot of great applications. We have crystal-clear, into medical, dental,
crazy-thin walls, and then the full color range. Now we’re talking about Agilus. So, if you want a Agilus30, it goes from Shore
A all the way up to 95. So, you can go from a really solid part all
the way down to a very, very flexible. So, if anyone’s familiar with the Tango
material or the Tango Plus material that replaced that, this is replacing the Tango Plus. So, it’s leagues better than Tango and twice
as better than… or two to two-and-a-half times better than Tango Plus. So, a couple little quick stats for you. So, here’s a Tango Plus column, the second
to the farthest right. Farthest right is our Agilus column. So, you can see the tear-resistance, much
higher in all respects, and then the elongation at break also. Tango Plus’s highest rating is the lowest
rating of the Agilus. So, it’s an overall improvement across the
board, and, yeah, great stuff to work with. Digital ABS, there’s another great material
that we’ve been working with. We did… I don’t know if you noticed, but we did
go from Digital ABS to Digital ABS Plus, and once again, Stratasys is constantly improving
all that material. So, this is 38 percent more impact strength,
and here’s just a quick chart of how much more it jumped up in comparison. So, there are two modes that you can actually
print it in. There’s a thin wall, and then there’s
a post that you can use, and then there’s also pre- and post-thermal treating that you
can also do to your Digital ABS to increase the strength as well, and heat deflection
ratings. So, it’s great. And then, if you’re the eyeglass world,
oh, definitely check out the VeroFlex, and its potential is great. It’s a real material, not nearly as flexible
as Agilus, but flexible enough to be an eyewear and something that will be used drop athletic
apparel, and it’s going to be… it’s definitely something to keep an eye on, because,
yeah. Here’s a nice picture where you can actually
give these lenses and things a flex. And then, full-color capability. So, eyewear and other… I don’t know. Off the top my head, other industries haven’t
really picked it up quite yet, but I’m interested to see where this material takes us. Now along with that, we also have the Vivid
colors. So, this is kind of what pushed us into Pantone. It is the Vivid line. This allows us to really match that passion
red or azul blue that are on the screen here. So, we can do the wood-like realistic textures. You guys have probably seen this in something
or at trade shows. They were at all of our booths. The perfume bottles are a little bit more
rare to come across, but you can come see some of those nail polish ones. They look like, if they’re on just a table,
they look pretty spot-on. Once you’ve picked them up and feel them,
you know they’re… the weight’s a little off, they don’t have liquid in them, and
you can start telling that something’s off, but yeah, visually spot on. This lens, it’s actually funny. It was printed the opposite side up, so this
side has actually been polished, but the other side is unpolished. And you can see how glossy and pristine it
is, and this looks like a production-grade part. So, a lot of automotive people don’t believe
us that, yeah, this came from a 3D printer. Some more of the product lines that are being
tested with it. And that leads us to the new stereolithography
machine from Stratasys. So, stereolithography. This is a layer-by-layer process from a vat
of material that’s getting pulled out as through the process of polymerization. There’s a broad range of applications. There’s great… I’ll say the propeller/impeller unique geometries
that would require a crazy amount of support material and post-processing in the PolyJet
or FDM side, stereolithography really lends itself to those industries. So, if you haven’t been hanging out with
the other VARs and stuff that have been selling a stereolithography for years, Stratasys has
created a video for you. So, here we go. It’s also mute, so pretend there’s happy
music in the background. So, yeah, it’s been four years in the making,
so it’s been used in Stratasys’s redeye company and the production-side for over four
years, and now it’s… with the advent of the patents going up from our competitors,
it’s being released to the customers now. And yeah, you may be familiar of some of the
prosumer SLA machines. This is the SL style from Stratasys. Bigger and more robust, definitely. If you have four or eight of those SLA machines
on a rack in your place, you should definitely look into this SL machine from Stratasys,
as we probably replace all eight of those with one of these. So, that’s just kind of the process, how
it works, great look at it. So, got a nice, little screenshot up of it. And yeah, Stratasys is using… one of the
most notable takeaways is this is an open-vat system, so it is just as configurable as one
of the open source prosumer versions. It’s just industrial production-grade version
of that. And yeah, down here you can see, if you’re
from the SLA world, this 355nm resin should ring a bell, but yet you can use any of those
in this printer. So, you don’t have to buy directly from
Stratasys if you have your own in-house version of that resin that you specifically tweaked
and use on your personal ones. Now, you can use it in a professional-grade
system with better software integration, more reliability and whatnot for your uses in-house. Build volume is actually pretty massive for
an SLA. It’s 20” by 20” by 23”. I know a couple of advertisements I’ve seen
are talking about 4” by 6” by 5”, so that’s some of the prosumer versions that
you’re kind of talking about. This is 5, 6 times the size of some of the
prosumer ones that you can get off the shelf. So, when you want large parts reliably and
with great resolution, what is that—0.0005-inch bits, top notch. And then, yeah, we also have… here’s some
more of the specs. It’s open vat. They have gone through and created four commercial
profiles for resins that they’ve worked with those producers on. So, you can get four commercially available
resins that are capped with the Stratasys stamp of approval thing. We’ve used it, we’ve tested it, this is
how you use it without any trouble. Otherwise, if you use the open-vat system,
Stratasys will and their support system will work with you to try to configure it, but
yeah. If you’re familiar with the SLA world, SL
is very similar in technology. It’s just the open-source version of it. And configuring the lasers and the cure time
and the dips and all that fun stuff does take some tinkering if you’re using your custom
open-system resins. So, it’s available. It is a hurdle to get over, but if you do
get over that hurdle, you do have something truly customized for your business, for your
particular application. So, it is, by a lot of our customers’ accounts,
a very worthwhile hurdle to jump through to get their custom resins into the machine. And then in here are the four verified materials. So, low viscosity, you have water resistant,
you have most likely clear, you have tooling, wind tunnel testing, you have investment casting
base, and then you have a general-use one that are currently there. And then, once again, when this was first
kind of announced a couple months ago, there was only two. Now there’s four. Stratasys’s continually adding more to this. Now, let’s talk about some of those softwares
in our last couple minutes. So, GrabCAD. It’s a free download. If you’re thinking about joining the Stratasys
family or if you already have it and you aren’t using GrabCAD Print, I highly recommend you
dive into this. It’s a great software package. It’s just like any other of your slicing
programs that you’ve used in the past: Catalyze, MakerBot Replicator, like all those fun platforms. It’s just today. Its user interface is nice. It’s clean. It’s crisp. So, easy to drop in. You can use STLs, or you can use native CAD
files. You can remotely access it and see how it’s
doing, how much material’s left in your machine, how many hours is left on your printhead,
so that you can order replacements or plan for being down so you can really get that
preventative maintenance upfront, as opposed to being reacting to a down printer. And you know, for the longest time I only
had a couple choices for info with Catalyst and Control Center from Stratasys. Well, now it’s not the case. So, this now turns into I believe eight different
in-fills, and then the question is what about Insight? If you’re familiar with Insight, there’s
a class that CATI offers and it is the layer-by-layer editing of models. Really advanced. If you need to go layer by layer and change
tool paths and really make a print the most perfect print in the world, highly recommend
going after Insight. And then if you saw I mentioned Advanced FDM
Mode before, what is it? Well, this is one CAD file that has multiple
bodies in it, and you’re able to select each individual body and change the porosity,
change the thickness of the shell, like you can change a lot of different things. You can create… you can change the diameter
of different holes to drop inset… or heat melt inserts into or helical insets. You can do self-supporting angles. Like, you can change how the support angle
supports different walls. There’s a lot of great stuff. So, once again, I call it like Insight Light. Advanced FDM Mode is inside of GrabCAD. It’s one of the best-kept secrets you probably
don’t realize you already have. So, if you’re using GrabCAD, you just go
to File>Preferences>FDM, and then enable Advanced FDM Mode, and it turns it on. So, you already have it if you’ve downloaded
GrabCAD. So, that’s the other funny thing, is there’s
no extra download. It’s already on your machine. You just need to activate it, like, by saying,
“Show me where it’s at.” But on this slide, you can see that GrabCAD
Print versus Insight, Insight does leagues more than GrabCAD does. Will GrabCAD Advanced FDM Mode eventually
get it? Eventually. Until then, you can use both Insight and GrabCAD
to accomplish your needs. So, if it’s a slight tweak, use GrabCAD. Or if it’s slight tweak, use GrabCAD Advanced
FDM Mode. If you have to go make this perfect for production
mode? Go Insight. You have multiple options to go through. So, here’s a quick reason of what you can
do. So, standard edition is just you drop into
GrabCAD, hit Print. Thin wall, is there’s a little checkbox
in the standard edition of GrabCAD now. It allows you to edit the file with just a
check box being like, “Yeah, change to thin walls.” There’s VRW. That’s Variable Road Width. So, this one over-extrudes the head for the
road widths to fill in gaps. So, now, once you start comparing the left
to the right, you’ll see that the Variable Road Width, it’s actually filling a lot
of the gaps that were left before. Then, creating other issues as well. Once again, that’s just a checkbox, so it’s
an easy button, and that’s why it’s not the best. Once you get into Advanced FDM Mode, you can
choose Surface. Surface faces and bodies and change the infill,
and you’ll know, “All right. That one by this slice is the best option.” But same time, this took a little bit more
time on the far right, while this one was just a checkbox. Literally took, what, three seconds to click? All right, maybe. Now you’re getting into what to do. So, let’s zoom in on this, really showing
the air gaps of what happens from just standard print. Might work, but might break. Thin wall nearly does… doesn’t do much
of anything. In specific cases, you can really see it shine,
but in Variable Road Width, fills it in over-extrudes in some areas, but leaves some other voids. Like, it just messes up some stuff. But then, Advanced FDM Mode really fill that
in. So, if you take your time and learn your tools
that you have available, you’ll know which ones to use when. So, the other cool thing on the inside of
this, we can select a face, we can increase the surface thickness, and just fix that area. Or, we can select the entire body, and then
we can dive into what percentage fill we want, what rigidity. We can even click this Advanced Mode of the
Advanced FDM Mode and dive into the angle of infill. We can change the angle of it, and we can
change it from hexagonal to the standard slats, the crosses that, cubes that Stratasys use. You can do double bends, you can do regular,
like, you can modify a lot of things in the advanced features of the Advanced FDM Mode. So, there are tons of stuff, and we have tons
of blog posts. I think we have about five up about Advanced
FDM Mode alone. We have about 14 or 15 Insight blogs, so if
you have more questions about that, dive into our blog or ask them now, and then with that,
let’s move on into to wrap up this thing. Very quickly is our voxel printing. So, a voxel is a 3D pixel, and you can think
of ways to color objects. So, yeah, if you have some progressive slices
and each one of these pixels was like this, you could create by stacking them on top of
each other, a bunch of different pixels of color, and then you can create this. Something that’s really unique and crazy
when you think about it. Like, you couldn’t CAD this out. Like, the time and intensity that would take
to 3D-model each individual pixel in this sphere, that… it’s only two inches, would
be astronomical. Like, it would be a team of people to accomplish
what. So, leveraging this new technology to create
voxels, to create unique interior colors or unique properties. You can mix materials in there too, change
the strength. That’s where this voxel printing is really
taking off. And then, of course, Laika Studios, one of
my favorites. If you haven’t seen Missing Link, Kubo and
the Two Strings, or The Boxtrolls, you’re missing out. But when you go watch that, it’s work-related
expense, so don’t worry. Go and watch it. Just realize most of those puppets in Kubo,
like 70 percent of those parts, were 3D-printed, and then, 70 percent of the 3D-print models
were not touched up after they were printed. They were just used right off the machine. You go watch Missing Link, now they were up
in the 90 percent of their puppets and things were 3D-printed, and 90 percent of their 3D-printed
puppets were not touched up. They were just taken off of the printer, support
material soaked off, and then they were put into production. That’s the power of this new Advanced FDM
Mode—or rather, hello—the new J750. You can bring stop-motion to life a lot faster
or production products to life very quickly. So, thank you for joining us. I believe my half hour should be just about
up. So, yeah, Kris, do we have any questions in
the chat?
