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






Enhance the appearance of your 3D printed object with custom colors and finishes. Choose from a wide range of paints and coatings to achieve the desired look and feel.

Plastics, Metals 

Customization is Available

Gloss, semi-gloss, flat, metallic, textured



Achieve a smooth and glossy surface finish through mechanical polishing techniques. This process removes layer lines and imperfections, resulting in a refined appearance.

Plastics (PLA, ABS) and Resins


Smooth and Glossy


Powder Coating

Apply a durable and protective powder coating to your 3D-printed part. This process involves electrostatic-ally applying a fine powder, which is then cured to create a tough and resistant finish.

Metals (Aluminum, Stainless Steel, Steel)

Standard, Metallic, and Custom Options.

Gloss or Semi-gloss


Bead Blasting

Utilize bead blasting to achieve a uniform and textured surface finish. This process involves propelling small abrasive particles at the surface of the object.

Metals (aluminum, steel, titanium) and Certain Plastics


Matte or Satin-like

3D Printing General Tolerances

General Guidelines When designing for 3D Printing


Tolerance Notes

accommodate 3D printing up to 24″ x 36″ x 36″ without the need to split and bond parts.

Minimum Feature Size

0.030″ – 0.060″ is typical.

Minimum Wall Thickness

0.020″-0.060″ is typical

Clearance Between Features

At least 0.030″

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.

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.
