In the field of mass production, the comparison between 3D printers and traditional molds:
- Mold durability: In production applications, the mold must be resistant to wear and tear, and it must be economical and affordable. Therefore, most molds are made of steel, and some are even made of cemented carbide.
- Mold manufacturing: Use 3D modeling software such as PRO-E to draw the mold diagram, and continuously adjust to achieve the final molding effect.
- Mould use: Mainly used in traditional injection molding, die casting, rubber and stamping products.
- Mould strength accuracy: The strength is confirmed according to the actual needs of users, and the accuracy is high.
- mold production time: relatively fast.
- mold economy: large-scale production economy is good, single piece and small batch economy.
3D printing technology
- Materials required for 3D printing: Consider the most suitable printing materials according to the actual needs of users.
- 3D printing molding method: Cumulative type, which is added up little by little, and the final print is completed.
- 3D printing uses: 3D printing of small and complex parts can be easily achieved, large parts, the overall printing patchwork.
- 3D printing strength accuracy: There are many comprehensive factors about the strength and accuracy of 3D printing. The accuracy of the 3D printer, the quality of the selected materials, and the accuracy of the 3D model map all determine the accuracy of the final product. The strength is acceptable.
- 3D printing production time: molding time is longer.
- 3D printing economics: large-scale production of poor economics, single pieces and small batches of good economics.
