/r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing and development of 3D printed parts and devices. Members Online Here is what I have been printing for the last two months! 384 hours of print time.
PLA virgin resin is perfectly safe, to the point it’s used for bio-compatible surgery sutures and the like. The problem is pigments and additive blends — there have been several anecdotal reports of toxic pigments (eg cadmium compounds) in cheap Chinese filament in particular. Those pigments are fairly bound up between the polymer molecules
Different Types of 3D Printing Filaments and Their Strengths Best Filament for Kids-PLA: PLA is the best 3D printing filament. PLA is adequately strong for toys and is mainly made from starch (corn) which makes it non-toxic. PLA is a natural material made chiefly from cornstarch or sugar cane.In a recent CIRI toxicity study, researchers found that exposure to the fumes created when printing ABS or PLA filaments, can “contribute to airway cellular injury and inflammation.” Based on f1239.
