If you've decided it was time to buy your first 3D printer, but you're not certain what to look for, we've a solution for you. Here are all the important things you need to know before investing in an 3D printer. What kinds of 3D printers Are there? Most people are unaware that 3D printing in itself is a very broad term used to describe all the technologies required for creating physical materials. Fused Deposition Modeling, also called FDM, is the most widely-known and most popular. Fused Deposition Modeling enables you to make models by extruding and heating polymer that is then layered layer by layer. Most of the 3D printers operate on this technology and are widely available and quite easy to locate. The other two types of 3D printing are SLS, Selective Laser Sintering and Stereolithography. Stereolithography also uses an additive process but uses a UV light beam to make a model harder instead of extruding plastic. SLS is similar to stereolithography, exc
