- Laser powder bed fusion (LPBF) is one of the most commonly used metal 3D printing processes. The process can deliver complex features, optimized geometries, lightweight parts and intricate designs. But, it’s not as simple as just pressing print. Incorporating laser powder bed fusion into an additive manufacturing workflow requires manufacturers to think differently about design, material and more. Additive Manufacturing Media editors Peter Zelinski and Stephanie Hendrixson explain how laser powder bed fusion works, its capabilities and limitations, and suitable applications for this 3D printing process in this video.

A very wonderfully presented video
This video is most important our next generation. So Thankful these guys👍❤👍
I love how you explain everything
Wonderful presentation!!!
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
amazing content and explanation
realy fascinating. Sounds like a thing from the future. Wish I had a laser powder bed to put some heat on...
Just wonderful
Excellent thanks!
Informative.
Such a good fukin video 🔥
How far can a laser beam be eficien to melt metal poder and wat kaind of laser to use?
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?
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?)
@@AdditiveManufacturing Thank you four your reply and also the detailed article!
Does the heat treat? shrink the material?
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.
Is it applicable to sand..like moonsand? Plastic?or even candy?
yes
Man if only NASA got one of these… think of all the lives saved if they had a *reliable* part manufacturing system.
Although the rocket construction managers would probably still ignore major problems
Taak 3D-printer
prolly my least favourite type of AM
We have to ask...what's your favorite?
