Pictured above is a futuristic electric bass guitar made of acrylic PMMA (polymethyl methacrylate), also commonly known as acrylic glass or acrylic, is a clear thermoplastic commonly used as a replacement for glass. PMMA is also commonly referred to as 'Plexiglass'. Produced as far back as 1928, PMMA is considered one of the most transparent plastics available today and can be used in many industrial applications today. Acrylic vs Glass PMMA is a better transparent optical prototyping material than glass. The material tends to fail when subjected to tension and compression, and careful machining methods must be used to avoid failure or fracture. PMMA prototypes, obtainable through high-tech CNC machining. PMMA machining by CNC is superior to all other technologies because CNC machining is faster, more reliable, cheaper and customizable to user needs. Acrylic Prototyping: 3D Printing vs CNC Machining PMMA comes in both sheet and tube forms and is ideal for subtractive machining processes, although it can also be used in additive manufacturing techniques. Acrylic prototypes in many different colors can be easily manufactured by CNC as the PMMA in stock is available in a variety of colors and end users can dye it to any requested color. After machining the acrylic sheet and making it into complex shapes, after proper grinding and polishing of the machined parts, the machined PMMA transparent parts are obtained. Acrylic material properties Compared with glass, acrylic prototypes are light, strong, economical and strong. This makes it an excellent material choice for sharp and durable prototypes. The list of some PMMA properties is as follows: Property value name PMMA (PolyMethyl MethAcrylate) Chemical formula (C5H8O2) n Melting point temperature 130°C (266°F) Standard injection mold temperature 130°C (266°F) Heat distortion temperature (HDT) 95 °C (203°F) at 0.46 MPa (66 PSI) specific gravity 1.18 shrinkage rate 0.2– 1% (.002– .01 in/in) Tensile Strength 65 MPa (9400 PSI) Flexural Strength 90 MPa (13000 PSI) Coefficient of Thermal Expansion (5–10)×10−5 °C−1 Visible Light Transmission 92% Acrylic Prototype Applications Any Want Any industry that finds a stronger, cheaper alternative to expensive and brittle glass needs PMMA prototyping. Security fences, LCD screens, windows, water tanks, medical equipment and lenses – all use PMMA instead of glass. PMMA prototypes have seen significant growth in the last decade as many industries have chosen PMMA over other materials in their products. Going deep into the Monterey Bay Aquarium to a depth of 10 meters, use PMMA instead of glass Clear glass replacement PMMA clear parts are an excellent replacement for glass. They are commonly used in both commercial and residential scale aquariums. Strong and transparent, PMMA is also commonly used as viewing ports and as complete pressure hulls for bathyscaphes. The material and its products are also used in lenses for automotive headlights and backlights. Many security vehicles, such as those used for riot control, often use PMMA as the primary material for windows, as it provides better protection against thrown objects. Due to its high strength, PMMA is used instead of glass for windows in many buildings. PMMA Art by Manfred Kielnhofer Artistic and Aesthetic Uses Many different prototypes have been constructed using PMMA due to its physical appearance. Products/prototypes made with this material have excellent reflectivity and are visually appealing to the whole. In order to attract the attention of the media and shareholders at the exhibition, many companies have chosen this material. Because of its forward-looking appearance, many prototypes of furniture, musical instruments, jewelry and cars were made using PMMA. Exquisite looking Lexus Perspex car sculptures are only made of high-quality PMMA Medical industry PMMA prototypes and their products are also widely used in the medical industry. Contact and spectacle lenses are often made using PMMA because they are less brittle than glass. PMMA also has good compatibility with human tissue, allowing it to be used in the treatment of cataracts. Both tuberculosis treatment and cosmetic surgery utilize parts made from PMMA. Besides these, it is also the material of choice for dentures. The process of making acrylic prototypes Several techniques exist for the rapid production of PMMA transparent parts and their prototypes. At Woneng, we have adopted a variety of rapid prototyping techniques to ensure that you get your prototypes in the most cost-effective and time-saving way, while providing top-notch quality. If the geometry is complex and needs to be polished by hand, CNC machining is usually used. With CNC, the prototype can perfectly meet the requirements of the design specification, requiring few changes. Injection molding is another common method used for rapid prototyping. Low-volume injection molding is ideal for 100 to 10,000 parts. Vacuum casting can likewise be used. However, these two techniques are generally used for less complex geometries. Additive manufacturing can also be effectively used for PMMA fabrication. 3D printing is the method of choice for its fast production, no waste, ability to create complex parts and excellent product finish.
