3D Laser Printer

Working with easy replication in mind, [Peter] is building a 3D laser printer. The majority of the machine is made from laser-cut acrylic held together by parts that are inexpensive and available at your local hardware store. In the end this will lay down a layer of powder, use a laser to fuse the powder together in the outline of your choice, then repeat. This is known as selective laser sintering which is sometimes used in commercial rapid prototyping and, like a lot of other cool technologies, came into existence as a result of a DARPA project.

Sorry folks, this is not a fully functioning prototype yet. [Peter] is searching for the right laser for the job and a source for the powder. If you’ve got a solution please lend a hand and let’s see this project through to completion.

Cyclonic Dust Seperation

[Don] was having issues with dust when working with MDF. He had a shop vac overheat and die because of it. When looking for solutions, he saw several systems that used cyclonic dust seperation. Not wanting to buy something he could make for cheaper, he left the store and started scrounging parts. You can see his home made system in the video above. This seems like an absolute must have item for any workshop. Great job [Don].
