Product Overview
GPT Precision provides SLS 3D printing for suitable custom polymer prototypes and parts.
Selective Laser Sintering uses a laser to fuse regions of polymer powder according to the digital model.
Confirm the polymer powder grade, availability and required properties during project review.
The final performance depends on material grade, processing conditions, orientation and post-processing.
Key Features
- SLS can be considered for complex polymer housings, brackets, covers, mechanical prototypes and components with integrated features.
- Because surrounding powder supports the part during building, the process generally does not require separate support structures of the kind commonly used in SLA.
- Однако, design accessibility and removal of unfused powder remain important.
Manufacturing Considerations
- Consider a component containing a main passage and several internal branches.
- Air may pass through the main channel while loose powder remains trapped inside a blind pocket.
- A successful flow check does not automatically demonstrate that every internal region is free from residual powder.
- During design review, identify internal passages, blind features and available removal openings.
- Where necessary, additional access may be considered for powder removal.
- The geometry must allow the proposed cleaning method to reach the relevant regions.
- If an opening will be closed after cleaning, the closure method and final inspection requirements should be agreed.
Quality Control & Inspection
- SLS components are evaluated according to the specified dimensions, состояние материала, surface requirements and intended use.
- Flow performance and residual-powder acceptance, where required, should be defined as separate criteria.
- The available inspection methods depend on feature access and project requirements.
Specifications to Confirm
| Polymer powder grade | Confirm grade, availability and required properties during project review. |
|---|---|
| Cleanout access | Identify access openings and any planned closure. |
| Flow criterion | Agree on the test conditions for the passages that must carry flow. |
| Residual-powder criterion | Define where residue is checked and what is acceptable. |
Assembly Considerations
Passage layout
Mark the main passage, blind branches and cleanout openings on a section view.
Inspection before closure
Identify which areas must remain accessible until cleaning and inspection are complete.
Acceptance checks
Use separate criteria for flow and residual powder where both matter.
