Manufacturing of acrylic prototypes

Machined, silicone vacuum overmolded PMMA prototype
In the prototype industry, acrylic, also known as PMMA, is a transparent prototype material. Acrylic prototypes are mainly made by cnc processing. Acrylic has a relatively good transparency effect, which can reach 95% of the light transmittance.

Disadvantages of acrylic prototype:
Everyone knows that glass is very brittle, and acrylic is a kind of plexiglass. Therefore, its physical properties are also very brittle, and the shortcoming of poor toughness causes the acrylic to break accidentally. In the process of prototyping, this is the focus of attention. If the machining process cannot be completed, it can only be replaced with other materials, such as PC.

Advantages of acrylic prototype:
The important thing is high transparency. After polishing, the transparency can achieve the effect of full transparency. This effect is called plexiglass in the industry, which is unmatched by PC materials. Although PC is also transparent, the effect is not as good as that of acrylic.
