What is the alternative to 3D printing?

3. Thermoforming

Thermoforming is a technique that shapes thermoplastic sheets into desired forms through heating, followed by applying pressure and vacuum to mold the material to a specific pattern. The plastic sheet is heated until it becomes malleable and then molded to create various objects ranging from packaging and trays to automotive and medical components.

This method stands apart from 3D printing, functioning more like a casting process, yet still provides a quick and cost-effective way to produce accurately shaped components suitable for mass production, all while using an extensive range of durable thermoplastic materials.

4. CNC Machining

Computer Numerical Control (CNC) machining is a subtractive manufacturing process that creates high-precision parts with complex shapes. It uses a variety of materials, including metal and plastic, to construct parts with exact specifications. With the aid of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) software, CNC machines convert models into detailed cutting paths for achieving the desired shapes.

CNC machining is suitable for making everything from simple to intricate components, proving to be a highly adaptable method for prototyping, low-volume, and mass-production processes. Compared to 3D printing, which may be slower for more complex designs, CNC machining can often produce parts at a faster rate with greater precision.
