Aluminum Alloy (AlSi10Mg) suitable for projects that combine "lightweight + heat dissipation/conduction + integrated complex structures," such as radiators, lightweight brackets, and complex runner components.
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.
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.

| Finishing | Sand blasting and tapping |
| Typical lead time | Related to structural complexity, quantity, support and finishing; clear delivery and expedited options will be given after uploading the file |
Used to improve the surface uniformity and look and feel of metal 3D printing, making the appearance more "industrially consistent". If there are requirements for the appearance surface, it is recommended to note the appearance surface and roughness preferences.
Used to obtain more stable thread assembly quality. Please indicate the thread specification (M value), quantity, location and assembly method (screws/bolts/connectors) in the remarks.
Suitable for structural weight reduction and integrated design; reducing overall weight while meeting strength requirements (common in brackets, shells, and structural parts).
It is more suitable for radiators, thermal conductive bases, parts with cooling fins and complex heat exchange structures, and can create more complex internal and external heat exchange forms.
Multiple pieces can be combined into one, reducing welding/assembly points and improving structural integration; it has obvious advantages for complex internal structures.
A more reliable thread assembly is achieved through tapping; for key hole locations and mating surfaces, more appropriate manufacturing and subsequent processing strategies can be planned during the planning stage.
| Material | Key Advantages | Mainly applicable | Not suitable |
|---|---|---|---|
| Stainless steel 316L (SLM) | Stronger corrosion resistance, suitable for moisture/salt spray and general metal terminal pieces | Corrosion-resistant functional parts, end-use parts, complex structural parts | Projects with the first goal of lightweight/thermal conductivity (AlSi10Mg is more suitable) |
| TC4 Titanium (SLM) | High strength-to-weight ratio, performance priority | High-end structural parts, lightweight end-use parts, and reliability-first parts | Budget-sensitive general purpose lightweight/cooling parts (AlSi10Mg is more economical) |
| Die steel 1.2709 (SLM) | High strength and good heat treatment performance, suitable for jigs/molds | Jigs and fixtures, mold inserts, high-strength structural parts | Parts focusing on heat dissipation/heat conduction and lightweight |
| White Nylon (SLS) | Wear-resistant and fatigue-resistant, suitable for batch typesetting of complex structures, high cost performance | Structural validation parts, assembly parts, wear-resistant moving parts | Terminal pieces that require metal strength/temperature resistance and heat dissipation capabilities |
| Black SLA Resin (SLA) | The appearance details are stronger and suitable for display and review | Appearance prototypes, review samples, photographic samples | Metal strength/temperature resistance/thermal conductivity requirements (AlSi10Mg is more suitable) |
AlSi10Mg is suitable for projects with "lightweight + heat dissipation/thermal conductivity + complex structure integrated molding", such as radiators, lightweight brackets, and complex flow channel components.
If the structure is not complex and cost-sensitive, it is usually more recommended to evaluate CNC machining; when assembly accuracy and appearance requirements are high, a combined solution of "printing + key surface finishing" can also be used.
We support mainstream 3D/2D project files:
Metal 3D printing suggestions are given priority STEP + 2D annotation, to facilitate quick confirmation of assembly and accuracy requirements.
The finishing is: Sand blasting and tapping.
Yes, but it must be "powder dischargeable and cleanable". Suggestions:
For assembly consistency and strength stability, it is usually recommended to reserve apertures Tapping(more reliable).
It is recommended that you write clearly when uploading the file:
You only need three steps: Upload drawings → Confirm project evaluation and quote → Production and delivery after confirmation.
