3D printers have come a long way over the years. Traditional models still have some limitations, including models with visible layers and uneven structural strength. These can be overcome by using robotic arms and multi-axis CNCs for conformal deposition. The cost for this approach can be high though. Freddie Hong, Steve Hodges, Connor Myant, and David Boyle have come up with an affordable way to upgrade 3D printers into 5-axis.
Prusa i3 MK3s was chosen for this project. The above video shows how it works.
