FAQ

  • Is SLS stronger than SLA?

    SLS is usually better for strong and durable nylon functional parts, while SLA is better for smooth, clear, high-detail resin prototypes and appearance models.
  • 2. What materials are commonly used for automotive components?

    We support a wide range of automotive-grade materials, including aluminum alloys (6061, 7075), stainless steel (303, 304, 316), alloy steels, brass, and engineering plastics such as PEEK and nylon. Material selection depends on strength, weight, corrosion resistance, and application requirements.


  • 7. Can you manufacture large or heavy-duty industrial components?

    Yes. We support manufacturing of large structural components, heavy-duty assemblies, and industrial equipment parts requiring high mechanical strength and dimensional stability.


  • 7. How do you ensure part cleanliness for medical applications?

    We apply controlled finishing processes and clean handling procedures to minimize contamination risks. Surface treatments such as electropolishing and passivation also help improve cleanliness and corrosion resistance.


  • How long does metal 3D printing take?

    Typical lead time is 5–12 days for many metal 3D printing projects. Lead time may vary depending on material, part size, geometry, quantity, heat treatment, CNC machining, surface finishing, inspection, and documentation requirements.

  • Can you achieve ±0.005 mm (±0.0002 in) tolerance?

    Yes, on suitable selected features subject to engineering review. This capability is generally applicable to rigid turned, Swiss, reamed or specially finished features and requires an appropriate process and inspection method. It is not a whole-part default tolerance.

  • What materials are available for SLS 3D printing?

    Common SLS materials include Nylon PA12, Nylon PA11, glass-filled nylon, flexible SLS materials, and special nylon options for specific performance requirements.
  • 1. What tolerance can you achieve for automotive parts?

    We typically achieve tolerances up to ±0.01 mm depending on part geometry, material, and manufacturing process. For critical components, tighter tolerances can be evaluated based on drawings and technical requirements.


  • 6. Do you provide welding and structural fabrication services?

    Yes. We support MIG and TIG welding, structural fabrication, frame assembly, and heavy-duty welded structures for industrial equipment applications.


  • 6. Do you provide inspection reports and quality documentation?

    Yes, we can provide full dimensional inspection reports, CMM measurement data, and material certificates upon request to support quality verification and compliance needs.


  • Is metal 3D printing suitable for low-volume production?

    Yes. Metal 3D printing is suitable for prototypes, custom components, replacement parts, pilot production, and low-volume metal production, especially when tooling cost is not justified or the design is difficult to machine or cast.

  • 9. Can you review my design before production?

    Yes. Our engineering team can provide DFM feedback to help optimize manufacturability, reduce production risks, and improve efficiency.


  • 7. Do you provide corrosion-resistant finishing options?

    Yes. Available finishing options include anodizing, powder coating, electroplating, passivation, and other surface treatments depending on material and application requirements.


  • 10. Can you help with process selection for my design?

    Yes. Our engineering team can review your drawings and recommend the most suitable manufacturing process based on performance, cost, and production efficiency.


  • What tolerances can you achieve on aluminum CNC parts?

    For general metal machined parts, unspecified dimensions follow ISO 2768-1 class m unless otherwise stated on the accepted drawing. Precision features can be held to ±0.025 mm (±0.001 in), with ±0.010 mm (±0.0004 in) available on selected measurable features.

  • What happens if my design changes after quotation?

    Send us the latest CAD file or drawing with the revision clearly identified. We will review the changes and confirm whether they affect manufacturability, material requirements, price, or lead time.

  • 12. How can I get a quotation?

    Simply upload your CAD files and project requirements. We will review your project and provide engineering feedback with a fast quotation.


  • What is SLS 3D printing best for?

    SLS 3D printing is best for strong nylon functional parts, snap-fit components, housings, brackets, jigs, fixtures, robotics parts, and low-volume production components that require durability and design freedom.
  • 5. What materials are commonly used for industrial equipment manufacturing?

    Common materials include aluminum, stainless steel, carbon steel, brass, copper, bronze, titanium, magnesium alloys, and engineering plastics.


  • 5. How fast can you deliver medical components?

    Lead time can be as fast as 3–7 days for prototyping, depending on part complexity and process requirements. We prioritize fast turnaround while maintaining high precision and quality.
