Metal Powder Bed Fusion (PBF) is an advanced additive manufacturing technique that creates complex metal parts by selectively fusing layers of metal powder using a high-energy laser.

The process involves depositing a thin layer of metal powder and then using the energy source to melt and solidify the powder. As each layer fuses, a three-dimensional object is built up step by step with precise geometry and intricate internal structures.

Simufact Additive can simulate the entire process and prevent costly issues during manufacturing.

Metal Binder Jetting is an innovative additive manufacturing process where repeatedly a liquid binding agent is selectively deposited onto a layer of metal powder. Step by step they then form a 3D part but within a fragile and unfinished state, the 'green part'.

After the printing process, the green part undergoes a secondary step to sinter the metal particles, resulting in a dense, functional metal component.
Simufact Additive offers the first dedicated multi-physics Metal Binder Jetting sintering simulation solution focusing on distortion due to the post build sintering process and its automated distortion compensation.

Simufact Additive’s Defect Prediction Solution revolutionizes Metal Laser Powder Bed Fusion with a multi-scale approach. Swiftly predict defects and optimize local parameters, all within full-scale geometries. This hybrid analytical-numerical model-based module enables rapid thermal history and defect prediction at individual scan vector and powder layer levels. Predict and mitigate risks of keyholing, lack of fusion, balling up, and surface roughness.

Machining is a subtractive manufacturing process that involves removing material from a workpiece to achieve the desired shape, size, and finish.

It typically involves using various cutting tools to remove excess material from a solid block or piece of material. This process is used to create precise and intricate components with specific dimensions and surface qualities. Machining is often required when 3D prinited metal parts need to match tight tolerances.

The module within Simufact Additive for subtractive manufacturing simulation, called machining, allows to simulate the effects of subtractive manufacturing processes on the part geometry and the residual stresses.

Geometry inspection is the process of evaluating the physical dimensions, shapes, and features of an object to ensure that it meets the specified design requirements. This is crucial to verify the accuracy and quality of manufactured parts.

Various measurement techniques and tools, such as coordinate measuring machines (CMMs), laser scanners, and 3D scanners, are used to capture detailed data about a part's geometry. The collected data is then compared to the original design specifications to identify any deviations or defects. This can be done with Simufact Additive to identify critical areas which require further investigation.

Directed Energy Deposition (DED) is an additive manufacturing process that involves precisely depositing material, in the form of powder or wire, onto a substrate using a focused energy source. This energy source can be a laser, electron beam, or plasma arc. The material is melted as it is deposited and fuses with the substrate or the previously deposited layers. DED is used to build up complex three-dimensional structures, repair existing components, or add material to modify surfaces.

This particular technology can be simulated in detail with Simufact Welding.
