Simulation-Driven Additive Manufacturing: From Concept to Validated Design
Industrial 3D printing has matured significantly in recent years. What started as a tool for prototyping is now used to produce complex, high‑performance components – particularly for metal parts.
At Additive Intelligence 4.0 in Gothenburg, Sweden, Hampus Olsson from EDRMedeso presented how additive manufacturing simulation helps engineering teams manage this complexity and move toward reliable production. Using Ansys Additive Manufacturing, he demonstrated how design generation, performance validation, and manufacturing validation can be connected in a single, simulation‑driven workflow.
The case for simulation in Additive Manufacturing
As additive manufacturing moves from prototyping to production, the importance of business case is growing. Advantages of additive manufacturing – such as increased design freedom – must be utilized to maximize product value. Meanwhile, the cost of getting things wrong increases: In metal additive manufacturing, issues such as distortion, residual stresses, and build failures often only become visible late in the process.
As Hampus described during the presentation in Gothenburg, increased design freedom does not automatically lead to better results. “This freedom of design can present the engineer with a bit of a conundrum,” he said, referring to the challenge of evaluating countless design parameters without simulation support.
Simulation addresses this challenge by helping engineers explore, evaluate, and down‑select designs early. By validating both product performance and manufacturability before printing begins, simulation reduces trial‑and‑error and increases confidence when moving toward production.
From concept to validated design
Describing the simulation‑driven workflow, Hampus explained: “We start by generating a number of different designs using an algorithm instead of doing it manually with CAD. The design performance – for example, structural dynamics or heat transfer – is then simulated, and an optimal design is chosen.
Lastly, manufacturability is assessed using additive process simulation, predicting common build defects such as distortion and overheating. Several design-and-test iterations can take place before hitting ‘print’, minimizing risk and enabling first-time-right production”.
What simulation‑driven design enables
Using simulation as part of the design workflow provides several clear advantages:
- Performance‑driven designs based on real physics
- More efficient material usage
- Faster design iterations with less reliance on trial‑and‑error
- Reduced risk for critical manufacturing defects
From design freedom to reliable production
By combining generative design, performance simulation, and additive process simulation, the workflow presented by Hampus helps maximize the inherent strength of additive manufacturing.
