3D Printing Plastic
Choosing Your 3D Printing Plastic
A variety of plastics can work with 3D Printing. In general, plastics 3D Printing materials can be divided into three types: plastic filaments, liquid resins, and plastic powders. The key distinction between these materials is different 3D Printing technologies. Fused Deposition Modeling (FDM) uses plastic filament; Stereolithography (SLA) works with liquid resins; both Select Laser Sintering (SLS) and Multi Jet Fusion (MJF) are using nylon powders. Material performance combines with dedicated 3D Printing technology, we can generate many possibilities through plastic 3D Printing.

Plastic 3D Printing Process
Different kind of plastics can be 3D prinetd, one of the most typical and special 3D printing
plastic is liquid resin. Generally, resin parts can be created by SLA/DLP. Let's see how SLA prints resin parts:
Step1 | Pouring enough liquid 3D resin into the material pool and make sure there is no debris in the material pool. |
|---|---|
Step2 | The laser light will be guided to right coordinates according to the computer-controlled mirror in the printer. |
Step3 | The scraper sweeps the material pool after one layer in being cured, which ensures an even surface. The balance weight can make sure liquid resin remains in the same place even though the print bed goes down. |
Step4 | The process repeats and the laser light scans the resin through the dancing spots, and curing the surface into a right shape. |
Step5 | The resin 3D prints will emerge from the material pool. |
Step6 | Takes time to wait for residual un-cured resins running down. |
Step7 | Send resin parts for post-processing, including ultrasonic cleaning, removing supports, re-curing through UV light, sanding, sandblasting, threading, tapping, painting, etc. |
