3D printing arbitrary shapes without sprues, by embedding them in 3D-printed clear plastic
by Cory Doctorow from on (#3RXAM)
3D printing complex shapes is hard; the additive nature of most 3D printing means that the printer has to create sprues (struts that support parts of the structure during printing, which have to be removed later), or add in material that can be dissolved in a solvent bath after main production.
