Types of 3D Printing

Generally speaking, FDM uses high temperature to melt the material into a liquid state, extrude it through the print head and solidify it, and finally arrange it in three-dimensional space to form a three-dimensional object. 

Selective Laser Sintering (SLS) is an industrial 3D printing process ideal for manufacturing end-use parts. In SLS, a laser selectively sinters polymer powder particles, fusing them together and building a part layer by layer.

Surface Finishing Options for 3D Printing

If you need to improve the strength, durability, looks, and even functionality of your 3D-printed prototypes or production parts, surface finishing is necessary. Explore these custom finishing options and there must be one suits your project.



Material Compatibility






Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.

Aluminum, Stainless Steel, Steel

Black, any RAL code or Pantone number

Gloss, semi-gloss, flat, metallic, textured



Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.

Aluminum, Brass, Stainless Steel, Steel




Powder Coating

Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.

Aluminum, Stainless Steel, Steel

Black, any RAL code or Pantone number

Gloss or semi-gloss


Bead Blasting

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.

ABS, Aluminum, Brass, Stainless Steel, Steel

What is 3D Printing?

3D printing (3DP) is a kind of rapid prototyping technology. It is advanced prototype engineering that uses powdered metal or plastic and other bondable materials to construct objects based on digital model files by printing layer by layer.


Zhongde offers 3d printing rapid prototyping services and solutions to meet your special needs, such as 3d printed molds for injection molding. Instead of being replaced by 3d printing, our injection mold tooling is from 3d printed molds, with low prototype cost.


Advantages of 3D Printing

FAQs for 3D Printing

What colors are available for 3D printing?

We have filament available in black, grey and green. Each object can only be printed in one color.

Can I submit more than one file at the same time?

Yes, you can.

How will I know when the print is done?

You will be notified via email once your print is completed. If any problems occurred during the printing process, we will get in touch with you timely.
