I tried to print these big dragon wings (around 60mm tall) but the membrane between nerves is very thin and translucent, in certain areas there are even holes (or lack of material). 3D Printer(s): I can't name all 14. If there are visible gaps on the roof part of your model or you'd like a stronger print, increasing the roof … Prepare your model for 3D Printing: learn how to create, analyze, export and correct your 3D models. 3D printing shells are more important than you might think. The hexagonal shape lends strength from all directions to the honeycomb pattern, and it is modeled after the natural honeycomb structure of beehives. Many different materials can be used for 3D printing, such as ABS plastic, PLA, polyamide (nylon), glass filled polyamide, stereolithography materials (epoxy resins), silver, titanium, steel, wax, photopolymers and polycarbonate. Eric Wooldridge of TAG, introduces the concepts of shells or internal wall thicknesses in 3D printed objects and their significance in product performance.
