3d Printing Technologies
FDM – Fused Deposition Modeling
Fused Deposition Modeling is the most common 3D printing technology for a reason. It is fast and generally reliable. In this method a filament is melted as it passes through a nozzle and the resulting liquid is deposited as the print. The printer builds up one layer at a time until the part is finished. Commonly the layer heights vary between 0.1 mm for high-quality prints to 0.3 mm for fast prints. FDM is suitable for most applications with the only downside being that there is no economy of scale with every unit printed taking the same amount of time.
DLP – Digital Light Processing
DLP works by exposing a photopolymer resin to a particular wavelength of light causing it to cure one carefully defined layer at a time. The projected light is aimed at the printbed by a Texas Instruments chip that has hundreds of thousands or even millions of tiny mirrors, enabling it to very precisely illuminate a point to be cured. Able to print at layer heights of as little as 10 microns, a DLP printer is capable of incredibly small layer heights. There is, however a direct trade off between print volume and resolution in a DLP printer.
SLA – Stereolithography
Stereolithography is a technology that uses ultraviolet light to selectively cure resin one layer at a time. The prints produced are very accurate and can show very fine detail. Unlike FDM printers, adding additional copies of a part does not necessarily multiply the production time. While properly cured prints are perfectly safe resin is not biocompatible and 3d printed resin parts should never come into contact with food or be injested.
