Other responses have mentioned that this can print without support structures, though, that feature alone is not unique to this design. SLS or the HP Multijet printers layer whole beds of powder and then fuse selectively, so in effect, the powder is the support structure. This approach could conceivably do the same type of construction in arbitrary space. (within a resin bed)
- rcurry 4y agoExactly. The firm I work for does a lot of 3D printing using the HP Multijet Fusion systems and we do not require custom support structures for anything. As you point out, the powder bed is the support.
- ncmncm 4y agoThis method can be much faster than others, because all the resin starts out in its final position, and only the laser light moves. The article contrasts it with another otherwise similar method that has to go very slowly because it injects so much energy per voxel the resin would boil if they went faster.
