3D Printing Combined with High-gloss Baking Finish: Driving the Innovation of Humanoid Robot Manufacturing

Comparing with traditional material decreasing manufacturing, like CNC machining, 3D printing is well known as additive manufacturing. The liquid resin(SLA) is cured by ultraviolet light and becomes solid layer by layer to form a model；Nylon powder or metal powder materials are formed by high-temperature sintering (SLS&SLM). So it allows us to realize complex part geometries by 3D printing.

Material Selection Guide

Choosing the right material depends on several factors:

  • Functionality: Will the part need to bear weight or withstand stress?
  • Environment: Will it be exposed to heat, moisture, or chemicals?
  • Aesthetics: Is surface finish or transparency important?
  • Budget: Some engineering materials come at a premium cost

Not sure which material to choose? Our technical team can provide recommendations based on your specific application.

About 3D Printing

3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects from a digital file.

Unlike subtractive manufacturing, which removes material from a solid block, 3D printing builds objects layer by layer, adding material only where needed. This fundamental difference enables:

Complex Geometries

Production of shapes that would be impossible or extremely difficult with traditional manufacturing methods.

Material Efficiency

Significant reduction in material waste compared to subtractive manufacturing processes.

Design Freedom

Ability to create organic shapes, lattice structures, and complex internal features without additional cost.

How 3D Printing Works
  1. A 3D model is created using CAD (Computer-Aided Design) software
  2. The model is sliced into thin layers by slicing software
  3. The 3D printer reads the sliced file and deposits material layer by layer
  4. Each layer bonds to the previous one to create a solid object
  5. Post-processing may be required (removing supports, curing, finishing)

History & Evolution

The first 3D printing technology was developed in the 1980s, but it wasn't until the early 2000s that the technology became more accessible. Today, 3D printing continues to evolve with new materials, faster printers, and expanded applications across industries.

From rapid prototyping to full-scale production, 3D printing is transforming manufacturing by enabling more agile, customized, and efficient production processes.

3D Printing Guide

Follow this step-by-step guide to ensure successful 3D printing projects.

1. Design Your 3D Model

Create your 3D model using CAD software. Popular options include Fusion 360, SolidWorks, Tinkercad (for beginners), and Blender (for organic shapes). Ensure your design is manifold (watertight) with no holes or non-manifold edges.

Pro tip: Design with the specific 3D printing technology in mind, considering its limitations and capabilities.

2. Prepare Your File

Export your model in STL or OBJ format, which are the most common formats for 3D printing. Check for errors using mesh repair tools if needed. Popular repair tools include Netfabb, Meshmixer, and 3D Builder.

3. Choose Your Material & Technology

Select the appropriate material based on your part's intended use, mechanical requirements, and budget. Match the material with the right printing technology for optimal results.

4. Submit Your Order

Upload your 3D model to our platform, specify material, finish, and quantity. Our system will provide an instant quote and estimated delivery time. For complex parts, consider requesting a design review.

5. Production & Quality Control

Once your order is confirmed, we'll begin production. All parts undergo quality inspection to ensure they meet our standards before shipping.

6. Post-Processing (If Needed)

Depending on your requirements, parts may undergo post-processing such as support removal, sanding, painting, or assembly. This step ensures your part meets the desired finish and functionality.

Design Best Practices
  • Maintain appropriate wall thickness for your material
  • Add fillets to sharp corners for strength and printability
  • Design with orientation in mind to minimize supports
  • Avoid overhangs greater than 45° where possible
  • Use hollow structures for large parts to save material
  • Include drainage holes for hollow parts when using resin
