Direct Metal Laser Sintering (DMLS)

More Info

Direct Metal Laser Sintering (DMLS)

The models are printed layer by layer with a laser that draws thin lines in the powder, which melts and bonds it together to form a thin layer of the model. After a layer is printed, a new layer of fresh powder is spread over the surface by a roller.

The printer has a print chamber which is heated to just below the melting point of the powder. The laser beam adds the extra energy to melt the powder and forms a solid model.

After a print job is finished, the result is a printed model with support structures to be removed manually.

Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS)

The printer has a print chamber which is heated to just below the melting point of the powder. The laser beam adds the extra energy to melt the powder, and forms a solid model.

After a print job is finished, the result is a big block of heated powder with the printed models contained inside.

Fused Deposition Modeling (FDM)

Fused Deposition Modeling (FDM)

Fused Deposition Modeling (FDM) is simple in principle. It can be compared with a hot glue gun with sticks of glue in it. The glue is heated up until it melts and is then pushed through a fine nozzle in the front of the glue gun.

In an FDM printer, a long plastic wire is used in place of glue. It is fed from a spool to the nozzle where the material is liquefied and ‘drawn’ on the platform where it immediately hardens again. The nozzle moves to drop the material at the correct location, drawing your model line by line. When a layer is drawn, the platform lowers by one layer thickness so the printer can start with the next layer.

If the model contains overhanging sections, the printer needs to build supporting material. Since the material of the model cannot be deposited in the air, the support material prevents it from falling down. This support material is fed through another nozzle. Afterwards, when the model is put into a bath with special soap, the support material dissolves.

Multi Jet Fusion

Multi Jet Fusion

Models are formed using the HP fusing and detailing agents working with HP Multi Jet Fusion technology and materials. Parts with precise features and high dimensional accuracy are obtained with HP’s unique Multi-Agent printing process. It is ideal for short-run manufacturing.

PolyJet

More Info

PolyJet

Objet’s patented PolyJet inkjet technology works by jetting photopolymer materials in ultra-thin layers onto a build tray, layer by layer, until the model is completed.

Each photopolymer layer is cured by UV light immediately after being jetted, producing fully cured models that can be handled and used immediately. The gel-like support material, which is specially designed to support complicated geometries, can easily be removed by hand and water jetting.

SLA/DLP

More Info

SLA Technology

The SLA 3D Printer uses a computer controlled laser to draw the first layer onto the surface of a liquid polymer, which hardens where struck by the laser. The model is then lowered,and the next layer is then drawn directly on top of the previous one. This is repeated until the model is finished.
In this way, layer by layer, an object is “drawn” in the liquid by the beam, with the layers being consolidated throughout the process.
