Each route below owns a distinct part of the topic. Start with the decision you need to make, then use the focused articles within that route.
3D Printing Processes & Comparisons
Compare SLA, SLS, MJF, FDM and metal printing through process limits, economics and the requirements of the intended use.
3D Printing Design, Materials & Finishing
Prepare wall thickness, supports, orientation and material selection together; finishing changes fit and should be specified before the build.
Before you release the project
- Define the function, environment and the question this batch must answer.
- Specify material grade, geometry, quantity, finish and the dimensions that control fit.
- Agree the inspection method and the evidence required to accept the parts.
- Record the drawing revision and approval before production begins.
Common planning questions
Which printing process is best?
There is no single best process. Define the part’s use, loads, temperature, detail and finish first, then compare the supported process and material combinations.
Does a printed material behave like the same material after molding?
Not necessarily. Build orientation, density, post-processing and the material formulation affect performance. Validate the properties that matter for the intended use.
