Poly(methyl methacrylate) (PMMA), also commonly known as acrylic or acrylic glass is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass. The Idea Shop stocks acrylic in following thickness and respective colors:
- 0.625" (1.6mm) Acrylic
- 0.125" (3mm) Acrylic:
- opaque red
- transparent red
- 0.25" (6mm) Acrylic
- glass texture
Working with Acrylic
Acrylic can be used in many different ways and also can be formed into different shapes and sizes. Depending on the scope of the project you either need to just use a laser cutter to cut your geometry or use a combination of methods listed below to fabricate your design.
Engraving is the process of incising small groves of patterns or shapes onto a hard surface. This process can be used to easily personalize items and imprint a specific drawing or sketch on a acrylic item. The easiest way of engraving is using the laser cutter since it is also designed for engraving besides cutting material. In order to engrave your parts, open your geometry in AUTOCAD and select the areas that need to be rastered and then in the layer selection menu select raster (represented by red color), after that follow the rest of laser cutting process explained here
There are may ways of cutting acrylic, depending on the geometry being cut and the size of the cut some tools give better results than other tools.
- For a cut length that fits inside a 24" by 18" box
- The the "'laser cutter"' is the ideal tool to use.
- The "'band saw"' is also a good alternative where the laser is cant be used but you need cut geometry that has curves and the material is too thick for the laser i.e 0.5". The band saw can follow almost any cut geometry, ideal for small parts. But note that the band saws cut quality and accuracy depends on the user and more than likely not be a match for the quality and accuracy the laser cutter will produce.
- If the cut length is bigger than 24" by 18" then there are a couple of options listed below
- The "'Pannel Saw"' is only ideal to make straight cut lines.
- The band saw is good to follow almost any cut geometry, ideally small parts that
