Polishing (the assembly surface is more stable)
Polishing and transition processing of the positioning surface and contact surface will help the fit of the fixture and the stability of repeated assembly.

Key Material and Manufacturing Parameters
Engineering note: Values below are typical reference ranges. Final manufacturability, tolerances, material condition, surface finish, cost, and lead time depend on the drawing, geometry, quantity, and selected process.
Upload CAD files and mark critical features for an engineering review before production.
| Process | SLA light-curing 3D printing (high temperature photosensitive resin) |
|---|---|
| Color | Gray (more towards engineering verification vision; suitable for fixtures and functional samples) |
| Layer thickness | 0.05–0.10 mm (commonly used); higher precision modes need to be evaluated (increased lead time/cost) |
| Dimensional tolerance | ±0.20 mm or ±0.20% (whichever is greater); for thermal environment assembly, it is recommended to mark the critical tolerance or note "precision first" |
| Minimum wall thickness | Non-structural appearance ≥0.8–1.0 mm; general structure ≥1.2–1.5 mm; fixtures/stress areas are recommended to be thicker and reinforced |
| Minimum aperture | Directly formed holes ≥1.5–2.0 mm; it is recommended to reserve a margin for positioning holes/fitting holes and re-expand/ream holes |
| Text/texture | The height of embossed characters is ≥0.4 mm; the depth of concave characters is ≥0.3 mm; the line width is ≥0.25–0.30 mm (larger is recommended for spray paint/screen printing parts) |
| Hardness | Shore D 80–90 (varies with formulation/post-cure) |
| Tensile strength | 40–60 MPa (strength and heat resistance are more stable after post-curing) |
| Elongation at break | 6–15% (High-temperature systems are usually more rigid; for impact/fatigue requirements, it is recommended to choose the toughness/nylon solution) |
| Temperature resistance | Approximately 120–200°C (depending on formulation and post-cure; please evaluate and confirm based on your target working conditions) |
| Thermal Stability Recommendations | When used for heat resistance verification/fixtures, it is recommended to evaluate post-curing and thermal cycle conditions to reduce the risk of deformation and dimensional drift. |
| Surface roughness | Ra ~1–3 μm (related to layer thickness/direction); sanding + painting can further improve the look and feel and ease of cleaning |
| Density | About 1.10 g/cm³ |
| Recommended maximum unit size | Depends on equipment and placement; it is recommended to disassemble/reinforce large fixtures and assess the risk of thermal deformation |
| Accuracy level | Standard accuracy / high accuracy (remark "key hole/critical surface/tolerance requirements" required) |
| Optional colors | Mainly engineering gray; if a more consistent appearance is required, painting can be evaluated (it is recommended to provide color swatches or reference pictures) |
| Assembly enhancements | support Threaded inserts; Please indicate the thread specifications (such as M2/M3/M4), quantity and location; please note if tapping/expanding/reaming is required |
| Finishing | Polishing, painting, screen printing, threaded inserts |
| Post-cure instructions | It is recommended that high-temperature resin be fully post-cured to stabilize heat resistance and dimensional performance; the appearance or fixture parts can be selected according to the requirements for post-curing strength. |
| Typical lead time | Related to size, quantity, placement and finishing; clear delivery and expedited options will be given after uploading the file |
Finishing
Spray painting (appearance and easy cleaning)
It improves look and consistency and makes surfaces easier to clean. If the fixture involves mating surfaces, please indicate this in the remarks to avoid affecting critical dimensions.
Screen printing (logo and scale)
Suitable for fixture numbers, direction marks, scales and logos; it is recommended to provide vector files and position and size descriptions.
Threaded inserts (durable assembly)
Used for screw connection and repeated disassembly and assembly to improve the reliability and life of the fixture (please note the thread specifications, quantity and location).
Why Choose Photosensitive Resin High Temperature Resistant - Gray (SLA)
More heat-resistant and stable (more suitable for thermal environment verification)
For heat resistance requirements of 120–200°C, it is more suitable for functional samples and fixtures that are close to heat sources or for short-term thermal testing.
Dimensionally more stable in thermal environment
Compared with standard resin, it emphasizes thermal deformation resistance; it is more friendly to positioning, assembly, and clamping applications.
Precision and details are still online
Maintain the detail performance advantage of SLA for projects that require crisp corners, text textures, and assembly verification.
Finishing and assembly friendly
Supports polishing, painting, screen printing and Threaded inserts; It is easier to achieve "available + maintainable" when used for jigs and fixtures.
Recommended Applications
- Heat resistance test/thermal environment verification: Close to heat source, short-term heating, thermal assembly verification
- Jig fixture: Positioning fixtures, assembly tooling, inspection tools, protective covers, etc.
- Dimensional stability is preferred: Want to maintain a more stable fit and positioning under temperature changes
- Functional prototype + available look and feel: It is necessary to verify the function, but also hope that the surface and details are acceptable
It is not recommended to use it directly (it is recommended to change materials/processes)
- Strong impact/high toughness: Frequent buckling, drop impact, fatigue resistance requirements → Tough resin/nylon is more suitable
- Long-term outdoor weather resistance: Long-term sunlight/humid environment → Weather-resistant materials or stronger protection solutions need to be evaluated
- Ultra-high temperature persists for a long time: Exceeding material capabilities or sustaining high temperature for a long time → Evaluate high-temperature engineering plastics/metal solutions
- High load and long-term use: Load-bearing structural parts/end-use parts → CNC/injection molding/metal is more stable
Design and DFM Guidelines
- First define the "thermal working conditions" and then determine the structure: Please indicate the temperature range/duration/whether it is exposed to heat sources; different working conditions have a great impact on the risk of deformation.
- Recommended reinforcement and thickening of fixtures and fixtures: Avoid thin-walls at clamping points and stress points; try to make the wall thickness more uniform to reduce warpage caused by thermal stress.
- Hole location and positioning surface: It is recommended to leave a margin for the key hole/positioning surface and process it twice; if strict fit is required, please provide 2D markings and tolerances.
- Inserts are preferred for repeated disassembly and assembly: It is recommended to add screw connections Threaded inserts, significantly improving the reliability of repeated assembly.
- Effect of appearance/painting on size: Spray painting will increase the local thickness; for the mating surface, please mark "No spray coating/size priority" in the remarks.

| HP Nylon & Fiberglass - Black (MJF GF) | Stronger rigidity and dimensional stability, suitable for load-bearing structures and positioning parts, and good consistency in low- to medium-volume production | Delivery of load-bearing structural parts, assembly positioning parts, and repetitive parts | Fasteners that require a certain degree of elasticity/toughness (needs evaluation) |
