SLS powder sintered 3D printed parts, suitable for functional testing and complex structural parts

SLS

Best for durable nylon parts with complex geometry, snap fits and low-volume functional production. No support structures are required.

  • Applicable materials: nylon, PA12.
  • Typical maximum size: 400×400×400 mm.
  • Typical accuracy/tolerance: ±0.1 mm.
  • Considerations: Parts have a naturally textured surface and may need finishing for cosmetic applications.
SLA high-precision light-curing 3D printed parts, suitable for appearance prototypes and fine structural parts

SLA

Best for high-detail appearance models, clear parts and smooth surfaces that need painting, polishing or assembly review.

  • Applicable materials: photosensitive resin.
  • Typical maximum size: 300×300×300 mm.
  • Typical accuracy/tolerance: ±0.05 mm.
  • Considerations: Standard resins may not suit impact-loaded end-use parts.
Multi Jet Fusion 3D printed parts for low-volume functional production

MJF

Best for repeatable nylon functional parts and small-to-medium batches that need consistent dimensions and efficient production.

  • Applicable materials: nylon, composite materials.
  • Typical maximum size: 380×380×380 mm.
  • Typical accuracy/tolerance: ±0.1 mm.
  • Considerations: Parts have a naturally textured surface; color and finish options may require secondary processing.
Fused deposition modeling parts for structural checks and fixtures

FDM

Best for cost-effective concept models, larger parts, fixtures and early structural checks.

  • Applicable materials: ABS, PLA, PC.
  • Typical maximum size: 500×500×500 mm.
  • Typical accuracy/tolerance: ±0.2 mm.
  • Considerations: Layer lines are visible, and cosmetic surfaces or tight tolerances may need another process.
Metal 3D printed parts for functional and low-volume production

SLM

Best for complex, lightweight or high-strength metal parts that are difficult to machine conventionally. Heat treatment and machining are available.

  • Applicable materials: stainless steel, aluminum alloy, titanium alloy, mold steel, etc.
  • Typical maximum size: 300×300×300 mm.
  • Typical accuracy/tolerance: ±0.1 mm.
  • Considerations: Supports, heat treatment and finish machining can add cost and lead time.
High-precision light-curing 3D printed parts, suitable for appearance prototypes and fine structural parts

DLP

Best for small resin parts that need sharp details, smooth surfaces and fast production.

  • Applicable materials: photosensitive resin.
  • Typical maximum size: 300×300×300 mm.
  • Typical accuracy/tolerance: ±0.05 mm.
  • Considerations: Best suited to smaller parts; resin selection determines heat and impact resistance.

Engineering-Grade 3D Printing Capabilities

Get file analysis, manufacturability feedback, process comparison and production review before your order moves forward.

  1. CAD File Analysis

    Upload STEP, IGES, STL or OBJ files to identify key geometry and prepare process, material and quotation options.

  2. Manufacturability Review

    Review wall thickness, supports, orientation, deformation risk, assembly clearance and finishing needs before production.

  3. Process and Quote Comparison

    Compare suitable processes by material, quantity, tolerance, finish, lead time and cost.

  4. Engineering and Quality Review

    Confirm critical dimensions, tolerances, finish and inspection requirements before production begins.

  5. Materials and Tolerance Guidance

    Choose materials and practical tolerances based on the use environment, assembly needs and post-processing plan.

How Our 3D Printing Service Works

Upload drawings, review the recommended process and quote, confirm engineering feedback, then track production and delivery.

  1. Upload Drawings

    • Upload STEP, IGES, STL, OBJ, DWG or DXF files with your material, quantity and finish requirements.
    • Key geometry is analyzed to prepare process and quotation options.
    • Timing: File analysis begins after a valid upload; processing time varies with file size and complexity.
  2. Project Quote

    • Review manufacturability, material, quantity, tolerance, finish and lead time.
    • Compare suitable 3D printing options and their cost and delivery tradeoffs.
    • Timing: Eligible standard parts may receive an automated quote; complex parts require engineering review.
  3. Engineering Review

    • An engineer reviews critical dimensions, assembly, strength and post-processing requirements.
    • Confirm any recommended changes before production.
    • Timing: Engineering review timing is confirmed after the files and requirements have been checked.
  4. Production

    • Schedule the confirmed process for prototypes, functional parts or low-volume production.
    • Inspect critical dimensions, appearance, assembly and finishing requirements.
    • Typical production estimate: SLA/FDM 1–3, SLS/MJF 2–5, and metal 3D printing 3–7 business days. Final timing is confirmed in the quote.
  5. Delivery

    • Parts are packed for their material and finish, with delivery tracking provided.
    • Project-specific inspection or material documents are available when agreed.
    • Shipping: Transit time depends on the destination and selected carrier and is confirmed with the order.
