3D4makers has a new filament: PLLA. It’s a PLA that might be used in new medical applications like tissue engineering. Tissue engineering is a domain in medical technology and has emerged as a promising alternative approach in the treatment of malfunctioning or lost organs where patients are treated by using their own cells, grown on a polymer support, so that a tissue part is regenerated from the natural cells.
JP Wille, the founding father of 3D4makers asked opqrstu3D to test PLLA in infill only settings. Meanwhile, Slic3r updated their infill patterns with a pattern called ‘3D Honeycomb’. This new infill pattern should, in theory, provide maximum strength in all axes while using the least amount of material to do so. Today opqrstu3D tested PLLA on ‘3D honeycomb infill only settings and the results look very promising. The prints are light weighted, very strong and looking real clear. The cube is a tissue engineering test. As the pict also shows; PLLA is also a promising filament for non-medical prints.
Tissue engineering has nothing to do with boats and ‘kroonsteentjes’, it’s about growing animal/human cells in biodegradable materials. To demonstrate the possibilities of PLLA on infill only settings, I downloaded the model of an ear and a nose by addamay123. Creatr printed slightly adapted versions on PLLA, 3D honeycomb infill only.
