Best channel I have finally discovered, thanks a lot for the uploads

Thanks Shao! Happy to help.

As an engineer I would have liked some comparison of the strength and the actual tolerance of MJF and SLS

Exactly my thoughts. This seems to be only a surface finish/process oriented video than anything else.

One can heck out datasheets at parts manufacturers as i.materialze, weerg, shapeways.

Excellent info - thanks!

With both technologies there is also capillary action at the edges of surfaces facing up. I never hear anyone mention this.

did he said MGF instead of MJF?

@cielvague 2 жыл бұрын

Yes, systematically. I wonder if he is French. I think I can still hear a very worked-on accent.

Did you say "did he said"?

for everyone asking: MJF parts have superior strength and flexibility and more homogeneous mechanical properties compared to SLS parts

@Rimrock300 Жыл бұрын

PA12 in MJF, 52 MPa tensile strenght, 15% elongation at break, vs PA12 in SLS, 48 Mpa and 20%. Those are the figures I am familiar with from my suppliers of parts. MJF being stronger and more homogeneous, thats right. Don't quite see the difference as 'superior', like 'in a totally different league.

imagine if hp couldn't just sit on their laurels relying on extortionate taxation and business fees to keep their rivals from being competitive, we might have consumer grade mjf by now.

Wow. Great info. Thanks. I have a question about wall thickness with SLS. I see a lot online about minimum wall thicknesses but nothing about maximum. what's a recommendation? The rectangular areas of the 2 identical parts in front of you with the holes in the corners, looks like that base area is several millimeters thick. Can I design a 7-10mm floor into my parts without issues of uneven drying or warpage?

What wall thickness would you recommend for watertight parts? Thanks!

Formlabs Fuse1 SLS recycles up to 70% powder.

@johndonovan7018 2 жыл бұрын

which is not ideal for SLS.. you can but not ideal. sls is dying to mjf so they are trying the gimmicks now

@Z-add Жыл бұрын

Sinterit new sls machine can do 78% recycled powder very close to hp's claim of 80%

"Some parts of MJF machines have been made with MJF technology". This is the typical chicken and egg problem!

The great tragedy for some of these parts is that they're designed from a paradigm of the conventional manufacturing process instead of for pure functional optimization.
