Use and environment
Describe load, temperature, exposure, handling and whether the part is a presentation item or working prototype.
Material selection
Choose a Material Around the Job
Material recommendations begin with what the part must do, the process that can make it and what is currently available.
Selection questions
Geometry and finish
Feature size, wall thickness, support, visible surfaces and post-processing affect the process choice.
Availability and evidence
A specific grade is confirmed during quotation. Technical properties must come from the relevant supplier data and test conditions.
When you are unsure
Select “Recommend a material” on the quote form and describe the intended use. The review will distinguish current availability from a general material possibility.
Material and finish decisions
| Requirement | Decision to make | Useful limitation to discuss |
|---|---|---|
| Visual model or display component | Detail, colour, visible faces and surface preparation | Support marks, seams and handling |
| Fit or assembly prototype | Mating interfaces, layer direction and inserts | Process-specific variation and the actual fit test |
| Part exposed to load or heat | Selected grade and supplier datasheet for the expected conditions | Printed orientation, environment and required validation |
Your quotation identifies the selected material grade, availability, finish and any test requirement. A photograph or generic material name does not establish a technical property. Share the expected load, temperature and exposure instead of selecting a material only by appearance.
Process options to discuss in your quotation
Choose the intended use first. The quotation confirms the specific grade, availability, finish and inspection scope for the file.
| Process / material selection | Applications to discuss | Limitations to resolve | Finish and example | Availability |
|---|---|---|---|---|
| FDM / selected filament grade | Appearance parts, assembly prototypes and model components | Orientation, layer surfaces, supports, mating features and use conditions | Define as-printed or separately agreed finish; see geometry examples | Specific grade, colour and quantity stated in the quote |
| Resin / selected photopolymer grade | Detailed presentation parts and prototypes with identified requirements | Support contacts, handling, post-processing and grade-specific properties | Define cleaning, curing and agreed surface work; see detail-planning example | Specific grade, process and finish stated in the quote |
The linked photographs show visible geometry; they do not verify the material or process used. Compare FDM and resin decisions, or use the filament selection and sourcing guide for general education.
