Types of Metal 3D Printing
There are mainly four types of plastic 3D Printing: FDM, SLA, SLS, and MJF.
FDM, as known as Fused Deposition Modeling, is the same as FFM (Fused Filament Modeling) and FFF (Fused Filament Fabrication). FDM fuses and melts thermoplastic filaments such as PLA filaments, ABS filaments, and PETG filaments, etc. The filaments are heated and melted through the hot nozzle and extruded on the build plate layer by layer to create an object.
SLA, also known as Stereolithography, uses UV-laser light to cure liquid resins layer by layer, and eventually create a solid object with highly detailed and smooth surface.
SLS, also called Selective Laser Sintering, uses a high-power laser to sinter polymer/ non-metallic powders in the selective area, fusing the material together and building a solid object. SLS is more complex than FDM and SLA due to the high laser energy and plastic materials.
MJF (Multi Jet Fusion), the exclusive technology invented by HP, is a process of deposit both fusing and detailing agents onto the powder bed by inkjet heads, then fusing the materials by infrared heating unit layer by layer until the object is formed.
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:
Material Preparation
Pouring enough liquid 3D resin into the material pool and make sure there is no debris in the material pool
Laser Light Movement
The laser light will be quided to right coordinates according to the computer-controlled mirror in the printer
Make sure each layer is even
The scraper sweens the material pool after one laver in beina cured, which ensures an even surace. The balance
weight can make sure the liquid resin remains in the same place even though the print bed goes down.
Process repeats until the final parts are shaped.
The process repeats and the laser light scans the resin through the dancing spots, and curing the surface into a right
shape.
Printing bed lifts up.
The resin 3D prints will emerge from the material pool
Let the parts sit.
Takes time to wait for residual un-cured resins running down.
Post-processing
Send resin parts for post-processing, including ultrasonic cleaning, removing supports, re-curing through UV light
sanding,sandblasting,threading,tapping,painting,etc.
