SLA – Stereolithography Apparatus (3D Printing)

The Vat Photopolymerization family of additive manufacturing processes includes Stereolithography Apparatus (3D printing). Using an ultraviolet (UV) laser beam, a polymer resin is selectively cured layer by layer to make an object in SLA. Liquid thermoset polymers that are photosensitive are the materials used in SLA. SLA is the most affordable 3D printing technology currently in use for products that require extremely high accuracy or a clean surface finish. The initial output from the SLA printed item in normal size might arrive in as fast as 1 day.

We are dedicated to turning your vision into reality. Let us help you bring your dream product to life!
 

SLS – Selective Laser Sintering (3D Printing)

A powerful laser is used by 3D printers to fuse tiny, powdered polymer particles together. The part is supported during printing by the unfused powder, which does not require any additional support structures. Because of this, SLS is perfect for difficult geometries including undercuts, thin walls, internal features, and negative features. SLS printed products offer superior mechanical properties and a strength that is comparable to injection-molded parts. The initial output from the SLS printed part in normal size might arrive in as fast as 1 day.

FDM - Fused Deposition Modeling, or FFF - Fused Filament Fabrication (3D Printing)

FDM - Fused Deposition Modeling, or FFF - Fused Filament Fabrication (3D printing)

It is an additive manufacturing process that belongs to the material extrusion family. In FDM, an object is built by selectively depositing melted material in a pre-determined path layer-by-layer. The materials used are thermoplastic polymers and come in a filament form. It could process a wide range of thermoplastic polymers and less costly than other 3D printing technology, so making it the most used. The FDM printed part with regular sized, could have the first output as fast as 1 day.

DLP – Digital Light Processing (3D Printing)

DLP – Digital Light Processing (3D printing)

Digital light processing (DLP) and stereolithography (SLA) are two 3D printing techniques that use liquid photopolymer resin polymerization to create parts. SLA traces each layer's form using an ultraviolet laser. However, DLP projects a mask of an entire cross-sectional layer at once. SLA yields products with a smoother surface resolution, while DLP prints much more quickly and affordably. SLA printing works very well for large pieces and is perfect for applications requiring precise surface resolution. For large parts, DLP printing will lose precision and smoothness. The initial output from the DLP printed part in normal size could arrive in as fast as 1 day.

MJF – Multi Jet Fusion (3D Printing)

MJF – Multi Jet Fusion (3D printing)

MJF 3D printing is a Powder Bed Fusion (PBF) technology that uses a heat source to fuse particles together in a build chamber filled with thermoplastic powder, which is often nylon or TPU. However, Multi Jet Fusion's method is different from SLS in that it doesn't make use of a laser. While SLS and MJF share many benefits, MJF often costs less and produces less waste. While MJF is now grey and might be dyed black, SLS sections are white and can be colored in a variety of ways. The first output from the MJF printed item in normal size might arrive in as fast as 1 day.
