Adam Savage Levels Up His Workshop 3D Printer!

Adam kicks off the new year with a massive 3D printer upgrade to his workshop! After diving deep into FDM printing and integrating SLA printing into his builds, he's finally trying his hand at SLS (Selective Laser Sintering) Nylon printing using the Formlabs Fuse. Getting this new system set up in the cave and calibrated is the first step, and then Adam and Norm try their hands first prints to examine the unique qualities of sintered nylon. What would you like to see Adam test with this new printer?

a 3D Printer is still a tool after all. Tools are like Pokemon, gotta catch em all, and they're always inventing newer, more legendary ones with every new generation.

It's amazing how free stuff can change your point of view

[@gieze91]

We had one of these machines at my old job and it worked incredibly well, though I would just make sure you keep on top of the dust! The thing becomes messy in no time at all, and you really dont want to wait until there is a fine layer of powder coating everything within a 10m radius of the machine. Upkeep is also critical, making sure to vacuum the filters and do as much cleaning as you can as often as you can afford - makes the machine run much smoother and you will get more consistent prints. We found a 50/50 mix of used and fresh powder to be about the most used powder to cycle before getting defects. Also as others have mentioned, you will end up with way more used powder than you will know what to do with so dont worry about designing parts to be volume efficient to maximise how much powder you can recover. Cleaning time is also something to consider so if you can just have a piece be filled solid you may as well just leave it filled to save on cleaning time. PPE is also super important! Nylon 12 can definitely impact your lungs and if I was ever a bit relaxed about not wearing a respirator it would noticeably impact my health. Otherwise happy printing!

[@MarkEmerAndersonII]

Yeah - personally I'd leave the lid closed just to avoid the powder getting everywhere. I have to deal with that enough when powder coating. I mean, I'm a PPE stickler but sometimes, the mess helps keep me that way.

[@SebastianWeinberg]

Isn't this technically _still_ fused deposition? It's just a different method of delivering the material to its destination, and a different method of melting it for fusion, but still the same fundamental principle of stacking slices.

[@EllisanLeonhardt]

@@SebastianWeinberg not necessarily. FDM is specifically referring to a machine that deposits material that is directly fused to the layer below it, usually by extruding a solid filament through a heated nozzle, and only deposits said material in the exact pattern that forms each layer of print, with the rest of the build volume remaining a void/air. This means any overhangs or floating pieces need supports to keep them in place for the duration of printing. SLS requires an entire layer of material dust in the build volume, which then a laser sinters only select parts of to make the solid component, before placing a whole new layer of material down and repeating the process. This also means that, since the parts are suspended in powder that is roughly the same density, there is effectively no need for support structures. You could think of SLS as working similarly to resin printing, just flipping the laser and build chamber, but really each type of printing is its own separate thing.

[@NefariousElasticity]

@@SebastianWeinberg FDM and SLS are different subsets of AM (additive manufacturing). Using a laser to sinter powder instead of using a nozzle to extrude molten plastic is a distinctive enough characteristic to merit labeling it as its own separate form of AM. If you don't adhere to that logic, you could also call MSLA/DLP printing FDM because the action of the printer is depositing resin by allowing it to flow on to the build plate and then fusing it into a specific shape.

[@capthowdy126]

i have 14 printers, its took me almost a decade to get what i have but this is goals. this is how metal 3d printing becomes something we can do in our homes.

[@treborrrrr]

As someone with the certs to do maintenance and training on these machines, I wanted to scream at the screen a couple of times here. The guy from Formlabs was way too lax about the safety IMHO. But I guess it looks better for the cameras if you're not wearing PPE and keeping the hood open. And for Norm. Hollowing out parts is not what you want to do here, unless you fill that void with other parts. You'll just end up with an excess of used powder. Shoot for 30% packing density if you can (which is hard to reach, I know, but hollowing parts is going to make it a whole lot harder :D ). It does feel wasteful to print solid but having a bunch of excess used powder that you don't know what to do with is also a pain. Also, make sure you follow the maintenance schedule on the machine. And for the optical cassette and filters I'd just do it before or after every print rather than waiting for the timer to run out. Makes it easier in the long run IMHO. Also keep things clean around the machine. Even a single strand of hair in the hopper can ruin a print if you're unlucky. And be mindful of the blasting media so that you don't bring it back into the Sift, too much of it will make the PrinterWatcher abort the print and you might end up having to discard a bunch of contaminated powder. I'd hope the rep from Formlabs went through all this but I kinda got the feeling he didn't.

[@mattrussell8813]

We will hunny comb our builds when possible to avoid elephant skin from solid parts

[@Daniel-rd6st]

As far as i have understood in this video, unused powder goes back into the system?

[@treborrrrr]

@@Daniel-rd6st It does. But it has to be mixed, in the case of PA12, with 30% fresh powder before it can be used again. The problem if you keep printing at low densities is that you end up with a hopper that is full of used powder that doesn't get re-used fast enough. You can technically use straight used powder but then you run the risk of poor quality or just failed prints altogether.

[@mattrussell8813]

@Daniel-rd6st yes but for quality you have to have a certain percentage of fresh to used powder because it gets heated and cooled on the MJF machines we run 70/30

[@jackhemsworth7515]

Ideally yeah. It's not pleasant for the lungs

[@FreejackVesa]

This model is designed to not require any respirator, according to form labs, IF you follow the proper procedure. Hence the gloves chamber, the cartridge system, and the integrated vacuum. The instructions state to use a respirator if local exhaust particulates are above a defined threshold (ACGIH Threshold Limit Value) but it shouldn't reach that threshold with proper configuration of exhaust. I would assume the form labs field tech would explain that to Adam. Pretty sure he'll be fine with or without one depending on his personal work practices.

[@TheBigburcie]

I think they were relying on the built-in ventilation to suck the dust to the back end of the cabinet. You can see it flowing that way in some moments. I think they were going with the 95% effective PPE as opposed to the full sealed enclosure.

[@neverendingstudent]

I certainly would. I like redundancy when it comes to *not* discovering new and exciting forms of lung cancer.

[@MatsukawaZaraki]

I feel like you could print these types of things already assembled to avoid that "won't fit" issue just because of not needing supports. I'd love to see you try that print!!

[@Ozmundas]

This was my thinking also ! I think they can print-in-place - would be neat to see them try again with that method... might have to adjust tolerances - the press fit looked a little too tight.

[@nox_tech_]

sintered powder will have different tolerances than plastic filament or resin. as is, with the current tolerances, the joints would fuse together and it would just be a solid figure. one way would be to adjust tolerances on the file as you said. a quicker way would be adjusting the printer setttings (if there aren't physical requirements needed, only thing would be aesthetics, only getting iffy if you push it too far). other way, that they're taking a whack at, is post processing (sanding/filing down would work eventually).

[@FectacularSpail]

This is so cool. It's amazing not just how much this stuff has advanced, but how much more accessible this tech has become over the last decade or so. I have a ~7 year old CR-10S (heavily upgraded) and I think I'm going to get a small SLA printer pretty soon. And this is like a legit industrial rapid prototype machine! Not exactly the kind of thing the average maker is going to have in their home workshop right away (Holy sticker shock, Batman!) but the fact that this is a thing you can own and operate outside of an industrial setting makes me super excited to see what kind of stuff will be available to the masses in just a few more years.

Being a big fan of 3D printing, I am THRILLED beyond measure that you kept in the ultimate fail of this build! Learning is always a process, as you often show on this channel. And to see 2 skilled builders, with years of experience in different methods, with some of the best tools possible, STILL manage to fail at your 1st attempt. And the humor and classic (in Heinaman voice) "Well, THAT didn't work..." attitude... chef's kiss! LOLOLOLOLOL!

[@Moxzot]

So I love that you kept in the mistake, it honestly makes the video better and will show the evolution of the process in the future.

[@monsterclosetcom]

We’ve all been there! In my experience nylon 12 does have some flex to it, but like any material it depends on the thickness of the structure. I created a set of ball and socket joints somewhat like those shown, but minimized the connection surfaces as shells approximately 1/4 thick to allow for enough give for insertion of the ball (without tolerance for a firm fit). Obviously good idea to prototype and print test fit fitted joints be sure they will function and snap together.

[@ralphj4012]

Yes, surprised me that there seemed to be no flex, despite some walls being 2mm thick. On further reading it appears the material may be 12CF, which is carbon fibre reinforced and may explain the metallic-type tapping sounds and rigidity.

[@Bad_Astronaut]

I love the fact that Adam and Norm printed action figures in parts when the sls process could have printed them entirely assembled in one go. Its like scratching the surface of what's possible and I cant wait to see them play with it more .

They can be dyed but since it's dark gray the options are of course quite limited. But Formlabs recently launched white nylon as well which can be dyed any colour you want.

[@mattrussell8813]

SLS parts don't get flexible with water they do with heat so when dye or cerakote them we have to watch the temperature we've left PA12 in water for a couple weeks all it did was absorb water

[@JustinBuildsThings]

Printing and handling powder media without ppe like a papr hood and a jumpsuit and gloves is a great way to get untreatable interstitial lung diseases and to bring aerosolizable powder home with you. The plastic sls companies like to pretend this is only a metal powder problem but it just is only presented as such because there hasnt been sufficient research to study in an additive specific context. The lung damage from similar powder media is well established in other industries. Wonderful tools, just need to be safe to use them. I cant believe you guys pulled an exposed chamber bin out with no ppe.

The gloves are a recent addition to the system. For years it didn't have those at all so reaching the buttons was easy. But, normally you'd start the sifting right away and leave it running as you're working. The vacuum is only used at the end when you're all done and you're cleaning up. But yeah, being able to reach them while wearing the gloves wouldn't be a bad thing for sure.

[@zachbrown7272]

when do you have to open it to press the buttons? Start the sift at the beginning, then start the blower, run them for the entire sift cycle, then deglove, start the vac, clean up, and you're done. most of the stuff you see them doing (taking the grate off the sifter) is just for filming.

[@rebzfx]

I would also suggest hand blasting the parts first before tumbling! Also a vibratory polisher gets amazing smooth parts - great for robots etc! (lost of detail ofc), also gives them a little wash. White powder is cool because you can dye it (not super easy to get consitant, but works with some additives and heat help). And when designing, you will find long flats warping potentially. So you may want to design fins/heat sinks in that get snapped/cut off if you get any issues (same with metal poweder printing) :) SLS moulds work well also! but Silicone sticks in all the pitted surfaces. So I spray seal with a matt lacquar or gloss depending on the cast finish I want + mould release. I usually find a 0.2 tollerance worked on the machine I worked with after a light vib polish.

[@captainkiddoregon]

Although it was pointed out several times in the comments that you should have used more precautionary measures for PPE I found the video pretty fun. I've been working for a large investment casting business for the last 45 years. We purchased our first 3DSystems SLA machine back in 1988 which was their SLA 250 (ser #3) which had a printing volume of 10"x10"x10". It was pretty slow but put us ahead in the Investment casting industry in using SLA patterns for casting. I got involved with doing the CAD work and setup for builds about 1990 and it is still my primary job. We now have 10 large machines which we have built over the years large 60"+ diameter patterns for things like Intermediate cases for jet engines for Pratt, GE and Rolls. We build them in segments and resin the segments together to form one whole pattern. Years ago we did look into having some gating built with SLS in the hopes it would be cheaper and easier than SLA gates. But found out there was a bit of process in needing tin infiltrate them with wax which helps with the casting process and also some surface finish. The surface finish also kept us from using SLS for casting patterns. So it never really panned out and we never really investigated the process since. I do like the nylon material you used for these figures. I agree the sound of them is pretty cool. Look forward to more videos to see what you create, especially as you get more experience in dealing with things like joints and such. Thumbs up!

I've played with SLS and you should print with it fully formed. Just keep a very small gap around the ball joints. Also, I developed a box for printing very small parts. When you print them, you print the box around them so they don't get lost or separated. I developed the box so that multiple customers could print at once and we wrote their name on the box. The lid was printed in place and just slid out after the cleaning. I created it in OpenSCAD and you simply enter the dimensions and the name and then render the box. Quite easy to do

My buddies and I were gonna pre-order a Fuse 1 to add to our print farm when they first enounced it. However after requesting some sample prints, we were not impressed. They were very brittle and broke with very little force, especially considering that it's nylon. Formlabs asked us if we wanted to place an order, but at that point we had more questions than answers. So after the parts weren't to our standards of durability, we started asking more questions about practical uses, but the Formlabs rep ceased communication with us after that. Apparently he didn't see a sale forthcoming...lol.

[@Saminvent05]

Having used a friend's fuse 1 I can agree with you. It feels more like a porous nylon network than cast and machined nylon. The refresh rates very quickly affect part strength even if the prints still come out looking nice. I would be very hesitant to use it for any thin-wall fragile parts, for thicker stuff it's probably more than adequate.

[@harvey66616]

Could some kind of annealing step improve the cohesion and durability of the print? That's something that even FDM prints benefit from, so I wonder if it's not a useful thing to do with SLS too.

[@ClayCowgill]

⁠@@Saminvent05it *feels* like it’s porous, but it’s not- you can cross-section it with a waterjet (or other cutting method that doesn’t cause melting) and the sintered area is solid. PA12 can be brittle if the part isn’t designed with the material limits in mind- PA11 is more ductile (super tough stuff). Orientation matters too since the layers are ~110 microns (the powder is ~80 microns) in the Z axis, but you get finer resolution as the laser sweeps in the X/Y axis.

As with any 3-D process you have to modify your CAD assembly tolerances to allow the parts to fit together. The ball joint you showed has an internal "overhang" that you need to account for the assembly in your CAD design with possibly more parts cut out the whole part.

@@Astromechy I think you are right. I intend tolerance as the movement that is allowed once the ball is in the receiver.

Did you do that full-time or part-time:)

[@nikhayes3396]

That seems to be the reality with every "first print" of any type of 3d printing. Adam says that its the hobby for people that like picking scabs, its more like a hobby for people that do not give up. Especially when you model your own projects in cad, I mean... its not difficult on a "standard" filament 3d printer to download an stl and follow all the instructions from previous folks that have already went through all struggles, but I endeavored to design landing gear and tires and wheels using petG and TPU filament and it took me several failed prints, and lessons learned before I was successful.

I’m so glad the patents are up on the powder deposition printers. We’re gonna get some crazy affordable printers soon

[@almonster2066]

Unfortunately CF12 is brittle and that SLS texture is very hard to cover over. Nylon doesn't allow most putty to stick very well. Not good for high fidelity models, but good for functional parts. They have other powders which have more durability (can take impact and have some flex). Also, wear a mask. You don't want to breath that stuff in repeatedly.

[@codewyzer]

@17:38 YES, the unused, powder is reusable after cleaned and removed from the printed part.. THAT is super cool! One of my biggest frustrations with FDM is the waste.

[@ducomaritiem7160]

From 2013 to 2015 I operated the Zcorp 450 color 3D printer. It used kind of the same system, but with plaster powder and a HP designjet inside. One of the printer cartridges contained a binder fluid instead of ink, the other cartridges contained the HP inks. Nice system...if it worked, very prone to errors and maintenance troubles...

[@curtisbright4012]

Sand down the joints, and give them a silicone, or some rubberized coating via dip or brush? The Ball joints need a millimeter or so removed, or, a small hacksaw, and a reprint of the balls in a flexible material. The elbows and knees would be a good way to test. But a misprint doesn't necessarily mean garbage. It might even make a whole episode of you and Norm figuring out how to salvage a project when something unexpected happens.

Talk about durable. Many years ago I had some French glacier glasses with nylon frames. After a few years I got tired of the side shields and took some shears to cut them off. No go. They just took it and refused to shear. Finally I had to hack saw them off. I used those glasses for like twenty years working outside in the snow and summer sun on the prairie. Finally when I left that life I gave them to a friend that was still out there and as far as I know they are still out there somewhere on some guys face.

10:00 Adam I think there’s a sand worm in your new printer, be careful

[@r4z0r84]

My exact thoughts, DUNE!!! Instead of dude haha 😂

[@landonholloway8979]

I’ve been using a gen 1 Fuse 1 and Sift exclusively with nylon 12 since spring of 2023 (before the Fuse Blast was available and before the Sift had cabinet-style gloves). I’ve always used the recommended 30% refresh rate (70% recycled powder mixed with 30% fresh powder) and I always have a surplus of recycled powder. I have two build chambers and I’ve been forced to use one for recycled powder storage. The sifted powder hopper in the Sift is always full so the incoming jobs I have to print are a challenge to clean. I know, packing density makes a difference but I have timelines, quantities and quality standards to meet. The Formlabs tech should’ve warned Adam and Norm not to both work in the Sift at the same time with the hood up and without respirators. The negative pressure is only effective enough for really dusty operations when the hood is down. I always wear glasses, gloves and a half face respirator when working with this stuff. Adam needs a vapor smoother next!

[@matahaikonen9390]

You should make some kind of wear test for that material.. maybe some gears with a motor and one offset weight.. or something like that.. just keep the motor spinning for a month or a year.. until something wears out

[@mattrussell8813]

We have a gear at work we've been running for a year holds up quite well. Here is another wear test with pa12 and tpu kzbin.info/www/bejne/rmqndYKLosSrr6csi=3bDUi9txZonYCZSN

[@Cragun.]

Yeah...I would have masked up for that. I do want to see them redo that print and put those together ... not sure if they just make the ball joints smaller or if there is a different nylon material that does have some flex to it they need to use.

[@johnderoy916]

Since no supports are needed wouldn't you be able to print the action figures already assembled with the ball joints just printing in place already together?

[@DasGanon]

Probably! It probably matters more on the tolerances than anything else.

[@demetriusmichael]

Looks like it’ll waste powder, so they want to limit their z height as much as possible

[@bosstowndynamics5488]

​@@demetriusmichaelYou have to fill the chamber anyway, and it doesn't really waste powder that much since you can run recovered powder through the machine again (there's a limit due to thermal degradation but it's not like all the dusted off powder goes in the bin). The bigger issue here is that to make it print in place you need clearance between each part so a print in place action figure in a single material process would be loose and floppy, whereas I think they're going for poseable

As its sintered nylon its best to polish parts that make contact with each other, if you want joints. Polished sintered nylon parts are self lubicating which is also a bonus.

[@lovetekman]

Please be careful around the nylon powder 🫣

The lack of PPE use was astounding and unnerving.

Print the male/female joints with some slots in them to allow for flex when assembling. You can also selectively thin the wall at those points when creating your wall thickness.

[@monshalagon]

Couldn't you print the action figure parts already assembled?

[@N94able]

No because you'd have one solid statue. Even if you were doing a statue you'd still probably do it in parts, just in case some thing went wrong.

[@wolffox008]

I have seen assembled parts in SLS. If you have enough clearance for the powder in the joint this will work. Formlab has a print in place little case that use that process.

I totally identify with Adam freaking out over the metallic 'clonk!' noise the prints make. If you're familiar with enough different materials, that noise SAYS 'hey, this is so rigid it will shatter rather than flex, and it means you can do thus and so with it!'. A delight to watch Adam's brain kick into overdrive, on camera, as it puts together what new things he can create with all this :)

[@IAmMaarten]

this seems perfect for printed chainmail. No supports means you can print it fully separated, and it's actually pretty strong

[@mattrussell8813]

That'd be pretty expensive chainmail I'm not sure the cost per build on this machine because I'm not sure on the ratio of used to new material per build. Ours is 30/70% and each build retails around a few grand.

[@LocoSunny]

Perfect timing. Im laying in bed with a hangover headache.

[@JoNnYB1969]

Remember Adam, safety first! Never clean SLS parts in the open like that with no respirator, lab coat, or eye protection. Always use the glove box closed with the fume hood running when extracting the parts, and conducting the initial scrub down on the part surfaces. Any time your transferring parts from the printer to the glove box or from the glove box to the media blaster wear PPE! I recommend having a PPE station with all 3 that stays in the printer room so the powder has a smaller chance of traveling through the shop on your personal clothing. Have a separate tub with seal to put your respirator into also so it stays clean. Also I'm very surprised the service engineer only covered temperature calibration when they installed it. Calibrating the printer for dimensional accuracy is crucial with any 3D printing. That way you can run your parts with nominal dimensions, and know they be within a specific tolerance the machine is rated for. That way you know your assemblies will fit together with the correct gap settings. I wish I could help you out. I'm heavy into AM technology. I feel there's so much that the service engineer did not cover that could have helped you're first print be successful the first run. I'm sure the assembly gaps on the models themselves are all wrong for the most part, but.... never let a service engineer install a 3D printer and leave without proving it's accurate within specification. It's also very weird the way that nylon 12 sounded, and way it fractured. You might need to set your temp settings cooler. Anyways I'm glad I found your channel. I've always been a huge fan!! Feel free to hit me up any time if you need help with CAD, and AM technology. I'd be glad to help. Cheers!✌🤓

The build area of such a large imposing(and incredibly expensive) machine is shockingly small...heh. Although you can dump a ton of small to medium prints in it at once since they don't have to be at the bottom stuck to a plate. They can float anywhere in the build volume.

[@Bigrignohio]

It's not your (build) size, it's how you use it.

[@tw16044]

You basically have to surround the build area with an oven to get the whole thing up to near sintering temperature, the a layer of insulation, then surround that with the necessary motors, controllers, laser, and optics. It's harder than you think.
