Plastic is utilized worldwide for daily necessities for prototype manufacturing and products. The medical industry and many other sectors use plastic prototype fabrication using state-of-the-art machines and techniques.

The plastic components produced in precision injection molding require a tight tolerance. That means that the requirements for the product have precise and accurate procedures. When not followed, it can break inside the mold.

Because the requirements will differ for functional and non-functional prototypes, creating a prototype for functional testing must show your consumers whether or not it shows the intended performance.

Some other factors as more precise and complex designing and prototypes, require more time, machines, and cycle time, so cost increases when you need more precise, intricate parts.

The resulting prototypes look like the mock-up of the end product with similar features. This process is also an inexpensive method for the creation of precise prototypes.

When materials have a high shrinkage capacity, they melt as they undergo the precise injection molding process. It ruins the product in the end.

3D FDM printers read the instructions of the CAD file and deposit the filamentous plastic layer by layer. After deposition, it undergoes a cooling and solidification process. After solidification, the desired surface finishing treatments are done to form high-quality 3-dimensional prototypes.

An example of this would be ABS, a thermoplastic polymer. This kind of plastic can retain its elasticity while going through high temperatures. However, its shrinkage of +/-0.06 is still not appropriate for precision molding. Glass and other resin can be added to reach the desired shrinkage. These help the material absorb the excess heat while keeping the plastic stable.

Material is the base of any part, so it is the key factor affecting all other matters, such as cost, manufacturing time, the accuracy of parts, and their demand in the market. You must select the material with characteristics that relate to your desired prototype.
