When comparing additive manufacturing techniques to its traditional predecessors, one test to anticipate is the contrasting differences in material properties. The very chart to the left provides an overview of performance criteria and how THREE-DIMENSIONAL printing and CAE compare.
Each 3D printing tactic yields a different set of mechanical and thermal properties, and even layer bonding qualities which set it apart from features produced via an injection moulding tool. Whether the material is known as a thermoplastic or a thermoset, these qualities will define it’s potential range of application opportunities.
FDM 3D printing concept and popular materials
Fused Deposition Modelling 3D producing technology has the particular advantage of using true thermoplastics. This gives engineers with a range of materials to select from that will act similarly to production materials that they are familiar with. Popular FDM materials which include polycarbonate and Nylon 12 can be used for pre-production componentry, however , the layered quality of filamente 3D printing as an illustration anisotropic characteristics that differentiate how the part acts big butter jesus started testing scenario.
Validating design performance virtually with simulation technology
This is where simulation helps us fill some predictive voids and prevents us from printing bad strategies. Granted, I would rather print a bad idea than mould and also cast it from a soft tool. 3D printing is certainly fast and costs have gone down, but stopping to evaluate your design performance virtually helps reduce wasted pays out at the printer and provides more insight to performance on the field.
Even when we have tooled parts that are very close to be able to production quality, virtual testing has some distinct advantages about physical testing. Specifically, it’s a perfect “noise” free conditions where we can truly compare apples to apple types. In addition , with simulation, we can visualise quantities such as solutions flow or stresses that are intrusive or expensive for you to quantify physically.
Physical Versus Virtual Testing Comparison
You can easliy now use 3D printing to help visualise analysis results. Simulation has always been a great visualisation tool but now we can “feel” the ones results and hold them in our hands!
Implementing simulation and 3D printing technologies for design marketing
Two of the most interesting advancements in CAE and ANIMATIONS printing are tools for shape optimisation. It’s worthwhile to run a single study for a single load scenario. The fact that value goes up by orders of magnitude when you can on auto-pilot optimise across multiple use or loading cases employing simulation technology inside tools such as solidThinking Inspire.
Marketing Workflow Using solidThinking Inspire
Topology optimisation tools have been around for quite a while and in the early years, they were limited due to figure constraints for typical manufacturing methods. Then these language got smarter to include provisions for manufacturing constraints to assure the optimised design are feasible.
Now that 3D prints is becoming a manufacturing option it opens up the doors for models that we had to “throw out” before. Just like traditional processing methods, there are process effects to consider.
3D Printing Progression Simulation Workflow
We could physically print hundreds of parts working with different build paths and process settings but the fact that soon becomes cost and time prohibitive. Simulation gear are now being used to take into account printing variables allowing engineers to help predict 3D printing process effects on the final piece.
