Its an powder based 3d printing type so it will always have some sort of roughness on the surface because of the powder (unlike resin). SLS prints are a little rougher but way cheaper for lower build numbers

Of course

The main difference is area-based printing vs point-based printing. MJF typically is more dense based on a larger area of the print bed being exposed to IR energy at once vs the laser tracing individual points in SLS. The IR energy of MJF creates micro welds between layers as it penetrates several layers deep on each pass. The build size and throughput go to MJF as well. It appears MJF has the edge on Flexural Strength and Impact Properties as well.

@@Extolinc Thanks for the reply. If you wouldn't mind going into more details on the impact properties, I would really really appreciate it.

I wonder if these resources on our website have the information that you are looking for: www.extolinc.com/services/ddc/#materials If not, please let us know. We'd love to help you with whatever you are working on. Send us a contact form (on our website) and mention that you're "JoeBlow" from KZbin. We'd love to have a conversation with you.

Hi Josef. Thank you for your question. Yes, with through-transmission laser welding, at least one of the plastic parts has to be transparent to IR. However, there are some materials that appear black/opaque to the human eye but are transparent to IR.

@@Extolinc Thanks. I requested a quote on your website a week ago and no one replied.

UPDATE! We can now weld two opaque plastic parts with our Direct Laser Welding technology. With this technology, the laser energy is applied directly to both halves of the assembly; the energy is not transmitted through a transmissive/transparent component. This opens the door to many new applications that benefit from the clean, precise welds that laser welding provides.

Unfortunately, no. We have tried using InfraStake to heat and insert threaded brass inserts and it does not work well. Thanks for asking!

Hi Mikele, thank you for your question. Yes! You can weld and glue TPU. You can also weld and glue the other materials: PP and PA12. We have an on-demand webinar all about welding and assembly of Multi Jet Fusion 3D Printed parts. Check it out here: info.extolinc.com/mjf-assembly-webinar-2021

Great question! There are options for colors. We can die the parts or paint them various colors. Also, if the material is TPU, they can be coated in a flexible color coating. Check out all the options here: www.extolinc.com/services/ddc/#finishingprocesses

This is what will happen if we let every major paper printing company make 3D printers.

Yes, those are layer lines. Thanks for your question!

(thought they could hide it at the bottom) probably a toy for the boss's kid

Don't forget the elephant.

pls respond

Coat the hot plate.

@@etube8967 What does the hot plate get coated with?

@@darrellboito8567 We coat our hot plates with PTFE. But it wears after 700-1000 cycles. Eventually we are not fully satisfied with PTFE coating. I think we have a lack of information on this subject.

Actually, it's both. The spinning and pressure causes friction which melts the plastic for welding. Thanks for watching!

@@Extolinc bro that was a dumb comment. It's not both the friction is what fused it. If spinning yeah is needed, but if they weren't touching witch is need for friction !!! Not spinning. Come on bud you could technically run them with severe pressure and do the same thing. :) spinning not need just friction

Rub

The purpose of the teflon sheet is to prevent the hot plastic from sticking. However, some materials are challenging and there is always some risk of sticking. If material sticks, it will usually still produce a good part. Too much sticking can cause build up on the teflon and then lead to bad parts.

Thank you for your comment. The tip (pencil) diameter of nanoSTAKE is 10 mm. I will have someone follow up with you at the email address you provided.

Thanks for watching our video! This spin welder tooling doesn't include any clamping. The parts are held in the tooling by friction.

Haha! Do you know him?

No, just seems sketchy... 🤷🏻‍♂️

Oh, yes. It is that fast. Pretty great, huh?
