Comparing 3D Printing Technologies

Most 3D printers generally follow the same basic principle: build a 3D object by stacking hundreds of thin layers. It sounds simple, but there are so many different methods of 3D printing that it can be hard to wrap your head around them all. In this video, I share a handful of objects printed using all kinds of different 3D printers.

Heya, I know you’re probably getting flooded with notifications at the moment from your new video, but I’m hoping you get this one.
I’m currently doing my senior capstone research project on 3D printing and vascularization of bioconductive hydroxyapatite… ie basically printing bones for medical purposes. I’m looking for some advise and potential ideas for either collaboration or just a bit of feedback. You’d be credited in my research.

No joke lol… hope you get back with me!

In your own personal opinion, what is the best 3D printing technology available as I remember seeing SLS 3D printing long ago and remember being massively impressed by the quality but as shown in your video the ‘pointy parts’ tend to lose definition depending on their size.

Hey Devin, I don’t know if you saw this on reddit or not but a couple of guys here in Indiana just came up with a new tri-color filament called “Filablend”. It’s looking like some pretty cool stuff. Some of the final printed pieces are very similar to your skull, the colors are pretty consistent and shift when you turn it. I’ve got some on order and can’t wait to try it out. It would be interesting to see what you might be able to achieve with it.

I think filament is one of the things that is most exciting about 3d printing currently. There’s constantly new materials being made and new processing that can be done to generate better quality prints or to create a printed part that has special properties.  Who would have thought that you could print something made with fire resistant filament? It’s crazy!    

It’s also very exciting to see what is coming down the pipeline hardware wise.  Companies like Prusa are continuing to refine parts and managing to make FDM even better by employing new processes and making the system more aware of itself. It’s great to see FDM improving because a couple of years ago people were saying that we had hit the mark of how well it could do and there wasn’t going to be any significant improvements in the foreseeable future. Obviously those people were wrong.  Hardware is getting cheaper and print quality is getting way better.  It’s pretty freaking cool.  Consumer / hobbyist grade SLA is starting to take off and that is also exciting. I’m waiting to jump on that train though. The resin needs to come down in cost before I can even think about buying into it.  I just love printing in general and it’s all super exciting to me, no matter what it is.

What is the format of 3D file used for the full-color models?

Owen Buckingham says:

I took a tour at Shapeways, super cool facility. Definitely recommend you go if your ever in NYC.

Cømet says:

Hey Devin, could you do a review on the SnapMaker 3D please?

HawkeyesTheMan says:

You should do a review on the ant mini ,it is a cheap 3d printer you can find on amazon and it has great quality prints

Darn, now I want to see the stream of you sculpting the dragon. Cool video as always!

Junghyun Oh says:

This video is a dictionary of 3d printers ^^love it♡

William Shreckengost says:

Excellent points on the drawbacks of each printing technique. It seems like the messiness of SLA and SLS, and the post-processing are usually overlooked in comparisons of technologies, which just go over how detailed each one is. I still find it amazing that after decades of injection molding being out of reach, that we’re all looking at extremely complex machines that don’t require molds, and either planning to, or waiting for the (sometimes likely, as with SLA) point where we can build or buy them, and make one-off parts literally in-house. Even if I never have a DMLS robot making tools in my workshop, we’re still seeing a revolution in how we look at manufacturing.

mynameisben123 says:

What are the sticks that build up near the filament reels when you were printing the light blue dissolvable support FDM dragon?

Ginger Prince says:

wait so was there just a small layer of PVA between the model and the support structure? or did you just set the support to PVA? If you did the thin layer thing, how did you do that?!? please help!

Builder's Mark says:

The color changing skulls are still the coolest! But I love the detail in the others too.

iulian muresanu says:

my printer’s on the way so there’d better be a future for 3d printing :))

Trystan Shields says:

I also want one of those skulls! Stunning

Lindy Design Lab says:

Great overview comparison of the technologies. I didn’t realize how finicky the resin curing and adhesion could be.

Kaoru Fuller says:

Why do you have two koi fish pegs?

EbonRaven says:

Thank you! I have an FDM printer at the moment and like it very much (except right now when we’re having a fight about feeding the PLA in. 🙂 I have an SLA printer that I backed on Kickstarter and keep hoping that it will arrive some day. But I have wondered since I first saw the SLA, how the SLA printers work. You’ve made it so that if my printer never arrives, I will at least know how it should have worked. 😀

Ian Beach says:

While the more advanced ones are neat, they all have the downside of being less sustainable, resins are not recyclable, sls wastes a lot of material.

Emily Kirkman says:

Great vid as always! 🙂 You should try an Anycubic Photon which is a good inexpensive DLP. If you have Facebook join the users group and or shoot Anycubic or Alice Yu a message they might could set you up with a deal since you review printers.

Ps also review a Creality Ender 2 if you get a chance.They’re a good cheap option and could be a great starter printer for some.

T4nm4y says:

I’ve been using the PolyJet printer! Removing the waterjet support is so satisfying xD It’s like a jelly! The stuff is also really good for machining because they are solid. You can also print rubber materials and mix the rubber with other harder materials to create different hardness/stiffness polymers!

''/ad says:

The dragon is super cool! What VR app did you use to sculpt it?

Car acc kashmiri gate says:

Will you make a video on how you model that

Essential EDM says:

I’m really interested in getting a tevo tornado but I am unsure of where I should buy from, gearbest is the cheapest but the official tevo store is in euros suggesting it would be shipped faster and without import duty to the uk, what would you recommend?

K K says:

My experience with SLA printing is mostly positive. I study 3D printing and modeling and we have a Formlabs Form 2 in our school (plus three other printers). In my opinion SLA is easiest to work with and there is no mess if done properly. Of course the print size is pretty limited but the results are amazing.

Inez Bangar says:

yoooo the resin printing is so cool! i loved the comparison, thank u so much!

Trystan Shields says:

I feel as if there needs to be a machine to remelt the 3D printing material so if you mess up on a print or have excessive support material you can just throw it in the machine and it creates filament to use once more so you can cut down on waste and I feel like it’d be better on the environment because most filaments aren’t biodegradable.

Muircat says:

I really like this. I’ve been wanting to make a video about the different types of 3D printing, and why you should use some over other vs their disadvantages. This is a great video to show people why 3D printing is so versatile and important in the big and small production industry. Great job, dude. Also, I’m not sure how feasible it is for you to do, or if you’d even want to, but I own a Form2, and I haven’t noticed nearly as many problems with it that you pointed out with your kit printer, so if you have the chance, maybe take a look into it.

Pete S says:

In FDM what process did you use to only get a small layer of PVA between the support and the model?

BreadStick says:

Why is there 2 koi fish pixels behind you



HaysModz says:

Just wondering if anyone who reads this likes slic3r better than cura or cura better than slic3r tell me why

Sean Ocansey says:

That squirtle is really cool (it’s all really cool)

Mr.Squibles says:

I am watching this on my iPhone and Siri popped up and I wasn’t sure why but it was because he says CRTenS and my phone thought itbsayed Siri ten ask. Hahaha

Rouverius says:

Joel was showing a fully cast iron process that a startup was working on in his area. So what is the strongest printed parts available to the general public?

Pierce Weber says:

do more 3d pens

skyjacker56 says:

hobby level at 500$ what about my dagoma neva is it junk because it was 249? i can say i had the jumpstart printer from matter hackers, that was 599$ it is junk.

I fucking love make anything videos!!!

Edwin Rodriguez says:

Would you be willing to print an item for a customer. I am looking for a mag well that would fit on a tacamo vortex paintball marker and would accept an milsig square head magazine?!?!?
