Sand blasting (more uniform surface)
Removes floating powder and slight roughness to make the matte finish more consistent; suitable for assembly parts, structural parts and batch appearance consistency requirements.
Nylon PA12-Solid White
Nylon PA12-Solid White belongs to the SLS nylon system, leaning more toward a "functional" choice: balanced strength and toughness, abrasion and fatigue resistance, and no support required, suitable for complex structures and batch typesetting production.
Quote checklist: Upload your 3D model and, when available, a 2D drawing. Identify the required process, material, quantity, critical dimensions, finish, appearance standard, and target delivery date.
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 | SLS selective laser sintering (PA12 nylon powder) |
|---|---|
| Color | White/natural color (typically fine matte texture; if you want a more uniform appearance, you can choose sandblasting/painting) |
| Layer thickness | 0.10–0.12 mm (common range, depending on equipment and layout strategy) |
| Dimensional tolerance | General reference ±0.20 mm or ±0.20% (whichever is greater); 2D tolerance or remark "Mate first" recommended for mounting holes/mating surfaces |
| Minimum wall thickness | ≥0.8 mm (recommended); ≥1.2–1.5 mm is recommended for slender/stressed areas; ≥2.0 mm is recommended near screws/buckles with fillets/reinforcements |
| Minimum aperture | Direct forming holes are recommended to be ≥1.5–2.0 mm; deep holes/long holes are recommended to be larger and powder discharge and secondary finishing are considered |
| Text/texture | The height of embossed characters is ≥0.5 mm; the depth of concave characters is ≥0.4 mm; the line width is ≥0.35–0.50 mm (painted parts are recommended to be larger) |
| Tensile strength | 45–55 MPa |
| Service temperature | About 120℃ (for short-term/working conditions, please evaluate based on actual usage requirements) |
| Density | About 1.02 g/cm³ |
| Surface texture | Fine matte, slightly grainy (powder sintering characteristics); sandblasting can be more uniform, and painting can achieve a more "finished" visual effect |
| Structural advantages | No support required, complex structure/inner buckle/porous array is more friendly; suitable for parallel typesetting of multiple pieces, conducive to low- to medium-volume production |
| Assembly enhancements | support Threaded inserts; Please indicate the thread specifications (such as M2/M3/M4), quantity and location; please note if enlarging/reaming is required |
| Finishing | Sandblasting, threaded inserts, and painting |
| Instructions for powder discharge | Closed cavities require design of powder vents/channels; complex inner cavities are recommended to undergo DFM in advance to avoid remaining powder affecting assembly and strength. |
| Typical lead time | Related to size, quantity, typesetting density and finishing; clear delivery and expedited options will be given after uploading the file |
Finishing
Threaded inserts (repeated assembly is more reliable)
Used for screw connection and multiple disassembly and assembly; please indicate the thread specification, location and quantity in the remarks (please also indicate if enlarging/tapping is required).
Spray painting (for a more “finished” look)
It can be matte/semi-matte/high-gloss and other textures to enhance the display effect; it is recommended to provide reference pictures or color/texture targets.
Why Choose Domestic Nylon-White (SLS)
Functional type is more stable: strength + toughness balance
It is suitable for structural validation, assembly parts and wear-resistant moving parts; it is more fatigue-resistant than resin and is more suitable for functional prototypes that can be installed and used.
No support required: complex structures are more friendly
It is easier to make inner buckles, grids, porous arrays, and complex shapes; it reduces support marks and finishing pressure, and is suitable for complex geometries.
Small and medium-sized batches are more cost-effective: parallel production can be typesetting
Producing multiple pieces in the same furnace achieves better batch consistency; suitable for trial production, small batch spare parts, and multiple version iterations.
Assembly enhancement selection clear
Supports sandblasting to improve consistency and painting to improve appearance. Threaded inserts Improve the reliability of screw assembly.
Recommended Applications
- Structural validation/functional validation: Strength and toughness are more balanced, closer to the experience of engineering plastics
- Assembly parts/clamping parts: Requires certain fatigue resistance and reliability (threaded inserts are recommended for screw connections)
- Complex structure: No support required, inner buckle/complex shape/porous structure is more friendly
- Small and medium batch: Can be typeset and produced in parallel, suitable for trial production and repeated delivery of multiple pieces
It is not recommended to use it directly (it is recommended to change materials/processes)
- Ultimate mirror appearance: It is recommended to evaluate SLA resin + fine appearance process, or switch to injection molding/machining
- High precision fit tolerances: It is recommended to reserve a margin and perform secondary machining, or directly CNC/injection molding
- Long-term high temperature/strong corrosion: Evaluate more temperature/chemical resistant material systems (e.g. PC, PEEK, etc.)
- Requires extremely high rigidity: Glass fiber reinforced nylon (MJF) or metal solutions can be evaluated
Design and DFM Guidelines
- Powder discharge design: For closed cavities/long channels, powder vents must be designed; it is recommended to have at least 2 powder vents and ensure they are accessible and cleanable.
- Wall thickness and uniformity: The minimum wall thickness is recommended to be ≥0.8mm; avoid large-area ultra-thin planes and sudden changes in thickness, and reinforce/round corners when necessary to reduce deformation.
- Hole location and fit: It is recommended to leave a margin for assembly holes/positioning holes and ream/ream them twice; for critical fits, please provide 2D tolerances or note "fit priority".
- Threads and repeated disassembly and assembly: Threaded inserts are recommended; direct tapping is possible but is not as durable as metal inserts (especially when disassembled and assembled repeatedly).
- Appearance and logo: The nylon surface is matte and grainy; sandblasting is optional if a cleaner look is required; painting is recommended for display parts and reference pictures are provided.
Comparison with common nylon/resin materials
| Material | Key Advantages | Mainly applicable | Not suitable |
|---|---|---|---|
| Nylon PA12-Solid White | The functional type is more stable, does not require support, and is suitable for complex structures and low- to medium-volume typesetting. | Structural validation, assembly parts, wear-resistant moving parts, small batch functional parts | Ultimate mirror appearance, ultra-high precision fit (requires secondary processing/process change) |
| Black Nylon (SLS) | Both are functional types; the black appearance is more resistant to dirt and is suitable for functional parts with color requirements; | Assembly parts, structural parts, wear-resistant parts, batch functional parts | The ultimate mirror appearance and high-precision combination |
| HP Nylon - Gray (MJF) | Better batch consistency and dimensional stability, suitable for repeated delivery | Small and medium batch functional parts, assembly positioning parts, repetitive parts | Ultimate mirror appearance (still needs spray coating/finishing) |
| HP Nylon & Fiberglass - Black (MJF GF) | Stronger rigidity and dimensional stability, suitable for load-bearing structural parts/positioning parts | Load-bearing structural parts, assembly positioning parts, functional parts with priority on dimensional stability | Fasteners that require a certain degree of elasticity/toughness (needs evaluation) |
| Tough SLA - Yellow-Green (SLA) | A more refined appearance with greater detail; and more impact resistant than standard resins | Appearance + prototype with certain toughness, buckle verification, light load function verification | Complex structure mass layout, wear-resistant for long-term use (better with nylon) |
