Simufact AdditiveSimufact Additive est une solution logicielle évolutive puissante permettant l'optimisation des process de fabrication additive (technologies lit de poudre : SLS, SLM, LBM, DMLS, EBM) pour une mise au point du process "du premier coup".

En prédisant les distorsions et contraintes résiduelles générées dans la pièce au cours de son process de fabrication, Simufact Additive guide l'ingénieur méthodes lors de la phase de conception process en remplaçant les essais physiques par des essais virtuels, réduisant ainsi la durée et le coût du cycle de développement et mise au point process.

Simufact peut être utilisé pour explorer les différents paramètres du process de fabrication additive et mesurer l'influence de :

  • Choix matière et caractéristiques de la poudre utilisée
  • Paramètres du laser (puissance, vitesse de balayage, largeur de faisceau, etc.)
  • Stratégie de balayage laser
  • Stratégie de supportage
  • Positionnement/orientation de la pièce
  • Direction de découpe du plateau
  • Etc.

Simufact permet de simuler la chaine complète du process de fabrication additive :

  • Impression 3D
  • Traitement thermique de détente
  • Découpe du plateau
  • Retrait séquencé des supports
  • Optionnel traitement HIP (Hot Isostatic Press)

Simufact Additive utilise des méthodes numériques avancées afin de prédire :

  • Les risques de défauts géométriques dus au rétreint, voilage, etc. (analyse des distorsions)
  • Les risques de fissuration pièce et séparation des supports grâce à l'analyse des contraintes résiduelles
  • La position optimale de la pièce permettant d'obtenir une distorsion minimale
  • Le besoin de structure de supportage et la structure optimale permettant de contrôler l'intégrité géométrique de la pièce fabriquée

Avec Simufact Additive, fabriquez vos pièces en impression 3D correctement dès le premier essai !

Exactly the right metal AM process you need

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.

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.

Print your 3D AM parts first-time-right with Simufact Additive


Design and optimise your metal AM process:

  • Optimise the build-up orientation and the support structures
  • Compensate distortion automatically to print the part as-designed
  • Indicate criteria-based part failures, e.g. recoater crashes or risk of cracks
Reduce costs icon. Product benefit.

Costing – Estimate your costs for single parts and the entire printing job.


Simplicity – No expert knowledge required as the software solution is designed to be user-friendly, intuitive and process-oriented.


Sustainability – Save material, time and money by replacing expensive and time-consuming physical tests with virtual tests.

"Additive manufacturing simulation methods helped in achieving a lightweight structure, distortion-free model, without residual stresses, which is more helpful to the AM designers to print the parts physically first time right."
