Fremstilling af akryl prototyper

Maskinbearbejdet, silikone vakuum overstøbt PMMA prototype
I prototypeindustrien, akryl, også kendt som PMMA, er et gennemsigtigt prototypemateriale. Akrylprototyper fremstilles hovedsageligt ved cnc-behandling. Akryl har en relativt god gennemsigtighedseffekt, som kan nå 95% af lystransmittansen.

Disadvantages of acrylic prototype:
Everyone knows that glass is very brittle, and acrylic is a kind of plexiglass. Derfor, 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.
