Molding is the process of manufacturing by shaping liquid or flexible raw material using a rigid frame called a mold. Plastic injection molding is one of the most commonly used manufacturing processes in the world today. However, traditional molding process requires high initial tooling cost, and engineers are often limited to many design restrictions.

Use 3D printing for mold making is a transformative technique that reduces the timeline from months and weeks to days and hours. In fact, replacing the machined pattern with 3D printed mold makes the mold-making process shrink by 40%.

Zortrax, a Polish manufacturer of 3D printers and filaments recently published a blog, in which shows you an overview and key benefits of using 3D printing in the process of industrial molding.

Key Benefits of 3D Printing in Modern Mold Making:
– Time & Cost Saving: Preparation of the master pattern is quicker and much cheaper compared to traditional methods – time is reduced from 50% up to 80% while costs are lowered by 40%-75%.

– Fast Design Iteration: With 3D printing, each variation can be created within hours and alterations can be made on the spot。

– Lower Capital Investment & Risks: Having a 3D printer makes the whole process less complicated as one does not have to delegate creating the mold to other companies.
