I operate a service bureau in California that specializes ONLY in HP printing called Streamline 3D, and this video was seriously on point. Even though MJF is what I do 12 hours a day, I don't think I could have added much more information here. Great work!

At 1:50 into the video you mention the 'detailing agent' being like a 'black ink'. The fusing agent is like a black ink. The detailing agent is generally colorless. Otherwise an informative, balanced presentation of MJF.

With MJF i always feel a mild powder residue on my fingers whenever handling parts. That said, this type of 3d printing did save our butts a couple of times. We were able to print some pretty challenging objects, like large (

What's with the beeping between jump cuts?

[@Alles_hier]

great explanation and very helpful . thankyou

Can two printed HP TPU rubber parts glue or head bond together? (post printing assembly)

[@MisterBinx]

Great video thanks.

Hi Protolabs, I’m a recently separated U.S. Navy service member and landed a position with 3D Systems. I’d love a copy of 3D Printing Handbook!

I want a battery carrier made out of nylon with this process. How will the part handle a temperature of 60 celsius? Will it deform in some way. The part is quite thin.

[@Richard0503]

This was excellent - thank you

[@RazDesignAB]

Great video!

[@d15p4tch6]

This was great

Formlabs fuse 1 sls also allows swappable build chambers.

[@jerometruitt2731]

How much?

[@artcast101]

Uh EOS SLS systems have switchable build envelopes to BTW...

A benefit not mentioned is the lack of supports.

He did. Maybe you should watch it again.
