![]() ![]() In resin form, it should solidify to form the object. What plastics can be used in additive manufacturing? In filament or powder form, the plastic should melt to form the object you are printing layer by layer. Two other technologies that can print with plastics are Material Jetting and Multi Jet Fusion. Therefore, for industrial and end-use parts, manufacturers might decide to opt for SLS (using plastic powders) or SLA (using plastic resins) technologies that offer more accuracy and part quality. Plastics are often used with this technology to create prototypes. However, the precision on FDM machines is not the same as other AM processes such as SLS or SLA. As you may know, the most popular and affordable 3D printing process, FDM, produces parts through the extrusion of plastic filaments. In the following guide, we will take a look at the most common 3D printing plastics. In the AM sector, 3D printing plastics are also very popular. Due to their low cost, ease of manufacture, versatility and water resistance, plastics are used in a multitude of products and sectors. However, given the growing environmental concern, plastics derived from renewable materials such as Polylactic Acid (PLA) are also popular on the market. Most plastics on the market are completely synthetic (most commonly derived from petrochemicals). A plastic is a material made of synthetic or semi-synthetic compounds that has the property of being malleable (capable of changing its shape). ![]()
