While I'm sure it's a challenge, after watching 3D printers evolve over the years, I've no doubt that random people will find unique and amazing ways to handle the problem.

Paper printers have been around for ages though, and decades of R&D have been put into them. 3D printers have started to find a foothold relatively recently.

The FDM 3d printer model took off ONLY because the patents around the FDM printing head expired.
