Inject molten plastic into your 3D prints to knit the layers together #3dThursday

Article excerpt

Magma is a fork of OrcaSlicer by MGunlogson on GitHub. It adds a triangle-like infill type that builds sealed vertical U-shaped channels inside your part, then injects plastic into them mid-print using the printer’s nozzle. The problem FDM parts are strong in XY and weak in Z. Bonding weakness on the layer lines results in parts that are much weaker and more brittle compared to injection molded ones. Magma attempts to finally solve this by injecting into U-shaped vertical channels to “knit” the part together vertically in the Z plane. The goal is to fix FDM Z layer weakness by truly printing in 3D. Status: It works in the slicer. I have not gotten a clean physical print yet. This is an open experiment, and I want testers with better hardware than mine. (Bug reports go to this fork, not
