Materials for Rapid Prototyping

Longsheng can source any other material on request for prototyping and production runs of custom parts. If you have special material needs, please contact us to provide you with a reliable solution.

Aluminum CNC parts


Offers excellent machinability, high strength-to-weight ratio, and superior corrosion resistance, making it perfect for lightweight, durable machined parts.


Copper displays excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and can be easily welded.

Brass CNC parts


Brass has desirable properties for a number of applications. It is low friction, has excellent electrical conductivity and has a golden (brass) appearance.

Stainless steel CNC parts

Stainless Steel

Stainless steel offers superior corrosion resistance, high strength, excellent toughness and ease of fabrication, ideal for demanding machining operations.

Titanium CNC parts


Titanium It’s a metal with excellent strength-to-weight ratio, low thermal expansion, high corrosion resistance; sterilizable and biocompatible for machining.

Plastic CNC parts


Plastics are also very popular option for CNC machining because of its wide choices, relatively lower price, and significantly faster machining time needed.

Types of rapid prototype

Rapid prototyping is a tool widely used in various industries, providing a variety of technology and material choices to meet different needs. This process also includes various types of prototypes.

This prototype is used to validate the feasibility and feasibility of product concepts. They are usually not the final product version, but can be used to test basic concepts and technologies.

Functional prototypes are used to test the performance, working principle, and operability of a product. They can simulate the basic functions of a product, helping development teams identify potential problems and improve design.

A display prototype is a type of prototype that focuses on appearance and appearance, usually produced by engineers or designers to make it as close to the appearance of the final product as possible.

Pre production prototypes are usually the final prototypes made before the product is put into actual production. These prototypes are used to validate batch manufacturing processes and ensure that the manufacturing of the final product can proceed as planned.
