PLA (Polylactic Acid) – PLA is probably the easiest material to work with when you first start 3D printing. It is an environmentally friendly material that is very safe to use, as it is a biodegradable thermoplastic that has been derived from renewable resources such as corn starch and sugar canes.What does 3D printer do I use?
Most 3D printing hobbyists use a Cartesian FDM printer. A Cartesian style printer moves the bed along the Y-axis while moving the X-axis and Z-axis with their own motors. A Delta style construction moves the extruder using three motors on evenly spaced rods-this construction is less ideal and not as common.
