3D Printing Guide

FDM

FDM (Fused Deposition Modeling) Is the 3D Printing technology most people are familiar with. It starts with a string of solid material called filament. This filament is fed into a heated nozzle where it melts and is extruded in a predetermined path, layer by layer to build the 3D Model.

This is the most affordable type of 3D Printing you can find, with the highest variety of materials. PLA, and ABS are the most common types and are available in a wide variety of colors.

FDM is great for quick, low cost prototypes for a wide variety of applications.

SLA & DLP

SLA (Stereolithography) and DLP (Direct Light Processing are similar technologies. They both use a photopolymer resin that is solidified by a certain wavelength of UV light. 

For SLA a small laser traces out the shape of each layer. For DLP a projector projects the whole layer at the same time to solidify the resin. Since both are done with light this gets much finer detail, much higher resolutions and an overall nicer looking print.

Although more expensive than FDM, SLA and DLP give you an almost completely finished product.
