Sanding (surface refinement)
Removes support marks and reduces layer visibility—recommended for cosmetic faces and presentation parts.
Standard SLA Resin (White)
Standard SLA Resin (White) is one of the most widely used general-purpose, high-detail materials for SLA 3D printing. When you need clean surfaces, crisp features, and an easy-to-finish white base for appearance review, presentation, or light-duty fit checks, it’s often the most cost-effective choice.
Ordering tips: For cosmetic faces, please define the “show surface” in notes. If you have critical dimensions / assembly tolerances, attach a PDF/DWG. We can review DFM and orientation before production to minimize support marks on key surfaces.
Key Specs & Ordering Notes
Before ordering, please confirm: (1) whether you need sanding / painting / silk screening / vacuum metallizing (affects appearance & lead time); (2) whether you need threaded inserts or tight hole tolerances (may require secondary machining); (3) whether you have show surfaces (orientation & support strategy matter); (4) whether your model contains thin walls / tiny holes / snaps (DFM review is recommended).
Values below are typical ranges and can vary with resin formulation, machine type, orientation, and post-curing. If you require a specific brand, certified data, or matched properties, please contact an engineer. For repetitive assembly, impact loads, or functional durability, consider tough resin, nylon (SLS/MJF), or CNC options.
| Process | SLA 3D Printing (Standard Photopolymer Resin) |
|---|---|
| Color | White (ideal base for painting; highlights surface defects—define cosmetic faces if needed) |
| Layer Height | 0.05–0.10 mm (common); 0.025 mm high-detail mode (higher cost / longer lead time) |
| Dimensional Tolerance | ±0.20 mm or ±0.20% (whichever is greater); for critical fits, add GD&T/notes like “accuracy priority” |
| Minimum Wall Thickness | Cosmetic non-structural ≥0.8–1.0 mm; general structural ≥1.2–1.5 mm; load / screws area ≥2.0 mm |
| Minimum Hole Diameter | As-printed holes ≥1.5–2.0 mm; for fit holes, allow stock and drill/ream after printing |
| Text / Texture | Raised text ≥0.4 mm; engraved depth ≥0.3 mm; line width ≥0.25–0.30 mm (larger recommended if painting/metallizing) |
| Hardness | Shore D 80–88 (varies by formulation & post-cure) |
| Tensile Strength | 35–60 MPa (post-curing often increases strength but can reduce toughness) |
| Elongation at Break | 6–20% (standard resin is typically more rigid; choose tough resin for higher impact/fatigue resistance) |
| Heat Deflection Temp (HDT) | ~45–70°C @ 0.45 MPa; for higher-temperature needs, choose high-temp resin |
| Surface Roughness | Ra ~1–3 μm (depends on layer height & orientation); sanding + coating can further improve finish |
| Density | ~1.10–1.20 g/cm³ |
| Recommended Max Part Size | Depends on machine envelope & orientation; large parts can be split and bonded or use alternate processes |
| Accuracy Options | Standard / High-accuracy (add notes for critical holes/surfaces/tolerances) |
| Color Options | White base; can be painted to matte / satin / gloss (provide reference photo if possible) |
| Assembly Reinforcement | Supports threaded inserts (heat-set inserts); specify thread (e.g., M2/M3/M4), quantity, and locations. If you need tapping / drilling / reaming, add notes. |
| Post-processing | Sanding, Painting, Silk Screening, Vacuum Metallizing, Threaded Inserts |
| Post-curing Notes | Post-curing improves strength/thermal stability and dimensional stability, but may increase brittleness; recommended for appearance parts |
| Typical Lead Time | Depends on size, quantity, orientation, and post-processing; upload files to get confirmed lead time & expedite options |
Post-processing
Painting (final look)
Matte / satin / gloss finishes available. Provide a reference photo or target finish for the most consistent results.
Silk Screening (graphics)
Good for logos, icons, and scale marks. Vector files and placement dimensions help ensure accuracy.
Vacuum Metallizing (premium appearance)
Metal-like visual effects and stronger presentation impact—best for demo parts (surface prep requirements apply).
Threaded Inserts (reliable assembly)
Improves screw joints and repeat assembly. Specify thread size, quantity, and locations in your notes.
Why Choose Standard SLA Resin (White)
Clean, neutral base for “finished look”
White is ideal for visual review and paint-ready finishing, making it easy to match product colors and branding.
Crisp details (text & textures)
Excellent for small lettering, sharp edges, and fine textures—great for design validation and presentation.
Stable dimensional performance
Well-suited for fit checks and interference verification. Mark critical holes/surfaces for accuracy-priority evaluation.
Finish & assembly friendly
Supports sanding, painting, silk screening, vacuum metallizing, and threaded inserts for higher assembly reliability.
Best For (Recommended)
- Appearance-first prototypes: design review, presentation, customer demos
- High-detail features: fine text, textures, crisp edges
- Paint & graphics: painting, silk screening, metallizing for product-like finish
- Light-duty fit checks: alignment tests, clearance checks (repeat assembly → add inserts or consider tough resin)
Not Recommended (Consider Alternatives)
- High impact / high toughness: choose tough resin or engineering plastics
- Long-term outdoor exposure: evaluate weather-resistant materials and protective coatings
- Continuous high temperature: choose high-temp resin or more heat-resistant materials
- High load long-term use: consider CNC, injection molding, or stronger engineering materials
Design & DFM Tips
- Define cosmetic faces: White can reveal support marks and sanding lines—mark show surfaces so supports can avoid key areas.
- Thin walls & long cantilevers: Orientation and supports matter; add ribs/fillets and avoid extreme thinness to reduce warp/break risk.
- Holes & assembly fits: For tight fits, allow stock for drilling/reaming; provide 2D tolerances or notes for critical features.
- Snap-fits: Standard resin is relatively rigid; repeated flexing may crack—use tough resin or redesign with larger radii and lower strain.
- Paint/metallizing and micro-details: Coatings can soften tiny features—use deeper engravings and thicker line widths if final finishing is required.
Quick Comparison with Common SLA Resins

|---|---|---|---|
| Standard SLA Resin (White) | Neutral white base, smooth surface, crisp details, paint-ready finishing | Appearance prototypes, review parts, display models, light-duty fit checks | High impact, long-term load, continuous high temperature |
| Tough SLA Resin | Higher impact resistance and fatigue performance | Snaps, clips, functional checks, repeated assembly | Ultra-cosmetic finish at the lowest cost |
| Clear SLA Resin | Translucency/clarity (polishable) | Lenses, light covers, transparent housings, visual flow parts | High-impact functional parts |
| High-Temp SLA Resin | Higher heat resistance and better thermal stability | Heat-adjacent components, thermal validation | Low-cost appearance-only projects |
