Design For AM Parts
Additive manufacturing offer unimagined design freedom. This requires new ways of thinking and approaches, since conventional production methods reach the limits of their feasibility, the innovative design concepts of additive processes begin. It will open up new opportunities since it allows the creation of parts which could not be achieved previously with traditional means.
Design for additive manufacturing
We can support our customers with a production-orientated design that corresponds to the component geometry, especially for AM parts. We provide technical feasibility study as well as adaption and design modifications. This set of rules and methods to design and redesign a part focuses on the production of this part at lower cost, with ﬂexibility and with the objective to make the most out of the process
Only an effective design will indicate the power and limits of the process. Printers and 3D printing materials have individual rules and characteristics that need to be respected in order to get the high quality 3D print.- Avoid angles, hard-to-clear volumes (powder difficult to remove) and geometries above empty space to limit supports
- Anticipate the direction of the shape on the platform as early as the design stage and interactions between parts on a same platform
- Promote internal channels with higher bend radius and maximize the line of sight in cavities to facilitate removal of powder.
Guide for DFAM- Setting the right wall thickness
- Choosing the right space between your moving parts
- Create a hollow 3D model
- 3D printing overhanging and thin parts
- Warping and deformation
- File resolution for 3D printing
Lattice structures offer the major advantage of reducing part weight without reducing part strength, which is very important in industries such as aerospace and automobile. Thanks to this unique design possibility offered by powder bed AM technologies, complex lattice structures can be achieved, impossible to produce by any other technologies.
Simulating composite structures
From sintering processes to polymer deposition techniques, ranging from metallic based applications in structural mechanics, there exists an high number of control variables and physical phenomena involved, all with a strong influence on the achieved behaviour of the final components. By simulating visualization before production, It can be used for viewing distortion trends, final residual stress, and the maximum stress components throughout the build. These visualizations enable users to select the orientation and strategy which best meets their part design intent.
