What Is Laser Powder Bed Fusion?

[@adarshvishwakrama77]

This video is most important our next generation. So Thankful these guys👍❤👍

[@zeeshanhameed96]

A very wonderfully presented video

[@TheZoneTakesYou]

The rough texture is great for bonding of a protective coating. The LPBF lab at my college gave us a tour and I have a photo of a fingerprint sized gothic cathedral made of Ti64! The window frames are so tiny, but it doesn't look like a mold-cast model

I love how you explain everything

[@psulzer3756]

amazing content and explanation

[@danieleromonsele]

Wonderful presentation!!!

[@martinm.1967]

Great explanation.

[@Freak563]

realy fascinating. Sounds like a thing from the future. Wish I had a laser powder bed to put some heat on...

[@AdityaKrishnan27]

Great informative video! Is the build plate reused? Like the powder that didn't get used in the part, can it be reused or does it affect the strength of the material?

[@AdditiveManufacturing]

Yes! In most cases LPBF build plates get resurfaced and can be used for 10+ print cycles. The resurfacing removes material and eventually the plate becomes too thin to withstand the thermal stresses and must be replaced. (We actually have a whole story on our site about a company that specializes in build plate management-might be worth a look: www.additivemanufacturing.media/articles/united-performance-metals-is-the-one-stop-build-plate-shop-for-production-am?)

How far can a laser beam be eficien to melt metal poder and wat kaind of laser to use?

[@gvcjbf1266]

Is it applicable to sand..like moonsand? Plastic?or even candy?

[@v1Broadcaster]

yes

[@peterpopeszku]

Does the heat treat? shrink the material?

[@AdditiveManufacturing]

Shrinking is not the effect typically seen with laser powder bed fusion parts during heat treat. The common effect instead is slight dimensional changes due to relieved stresses. Manufacturers experienced with LPBF know how to anticipate this and adjust for it, either in the design of the part or by adding extra stock for machining later.

Informative.

Such a good fukin video 🔥

Man if only NASA got one of these… think of all the lives saved if they had a *reliable* part manufacturing system.

[@pizzainc.1465]

Although the rocket construction managers would probably still ignore major problems

[@KrisRyanStallard]

What are you talking about? Only about 30 astronauts and cosmonauts have died since the beginning of the space race. Yes, it's terrible when anyone dies, but given that NASA specializes in bleeding edge, bespoke technology for sending delicate human bodies into a void that wants nothing more than to murder them, they've had a decent track record.

We have to ask...what's your favorite?
