Re: carbon 3D

As a non sticking layer they use a fluorpolymer, e.g. Teflon AF 1600 or AF 2400. The AF 1600 and AF 2400 have a high oxygen permeability and cost 1800 dollars per 25 gram. The speed of the object's formation depend on the viscosity of the resin η, atmospheric pressure , the height of the gap between...

Re: DLP Metal Printing

It's complicated. You have to dissolve a fine ceramic powder in a solvent. To dissolve the alumina you can use a dispersant. A dispersant increases the separation of particles and prevents settling or clumping of the alumina. Then you add in the monomers and the initiators. You can use a speedmixer ...
