Processes of Additive Manufacturing

In order to produce increasingly innovative parts, with optimized functions and designs, industrial companies are now shifting towards additive manufacturing. This manufacturing method breaks away from the constraints of traditional processes and offers new kinds of solutions.

Laser melting on powder bed (SLM)

The SLM is an additive manufacturing technique that can print metal parts in complex geometries. The SLM uses a laser to melt successive layer of metallic powder. The laser will heat particle s in specified places on a bed of metallic powder until completely melted. Then, the machine will successively add another bed of powder above the melted layer, until the object is completely finished.

Electron beam additive manufacturing (EBM)

The EBM process is based on a high power electron beam that generates the energy needed for high melting capacity and high productivity. The powder bed is selectively melted layer-by-layer by an electron bean under high vacuum atmosphere. EBM has many unique characteristics such as high energy efficiency, high scan speed, and moderate operation cost.

Direct Energy Deposition (DED)

The DED is known as direct energy deposition or laser cladding. The powder delivery through a nozzle on the laser beam path. A laser beam is irradiated where the powder and the target substrate meet, the materials are melted and solidified through cooling. The LDM technology is used to repair parts or make a complex geometry on a large scale.

Selective Laser Sintering (SLS)

SLS system manufactures polymer parts by adding consecutively material layers. It uses a moving laser beam to trace and selectively sinter powdered polymer into successive cross-sections of a three-dimensional part. The parts are built upon a platform that adjusts in height equal to the thickness of the layer being built. The commonly applied SLS powder to date is polyamide 12(PA12).

Stereolithography Apparatus (SLA)

SLA is a technology to produce plastic solid objects parts in layer by layer fashion using a vat of liquid as UV-curable photopolymer. The laser beam traces the boundaries and fills in a two-dimensional cross section of the model, solidifying the resin wherever it touches. Models are built to an accuracy of +/- 0.2mm, typically in layers of 0.1mm thicknesses.

Digital Light Processing (DLP)

DLP is a process where a projector is used to cure photopolymer resin. The parts are created by successive layers of photosensitive epoxy, acrylate or composite resin under the action of a high-intensity ultraviolet laser. Compared with SLA, DLP can have faster build speeds due to a single layer being created in one singular digital image. DLP is used to generate highly detailed artwork and non-functional prototypes.
