What's the difference between 3D printing technology and traditional molds?

3D stereoscopic printing, also called rapid prototyping;

1, basic material: resin. Now all products are laboratory products. The availability of other materials is still under development.

2, molding method: the material is added bit by bit.

3. Direction of use:

At present, there are two main applications of this thing: large parts and some small and complex parts formed by molds.

4. Because the materials used have not been confirmed, it is judged that the strength accuracy of 3D printed products is not enough.

5. Long molding time

6, other unconfirmed

Mould:

1, it must stand wear and tear, and it is relatively cheap economically.

Therefore, most molds are made of steel, and some cutting edges of mass-produced molds will use cemented carbide.

2. Three-dimensional modeling of mold manufacturing is the foundation, and most of them draw pictures with composition software such as PRO-E first.

Then automatically generate the tool feed stiffness required by CNC machine tools, and then manually adjust some unreasonable parts.

Final processing and molding (injection molding or stamping)

3. Direction of use: traditional injection molding or stamping products.

4. The strength and precision can be determined according to the purpose of the product, and the precision is high.

5. Rapid prototyping
