Are you new to 3D printing and have no idea what 3D printing material to use? With the popularity of 3D printing in Singapore these days, many new materials are surfacing and it may get all too complicated for a beginner. With this guide, discover commonly used 3D printing materials and carefully select the perfect one for your application!
ABS is one of the most commonly used FDM 3D printing plastics. Short for Acrylonitrile Butadiene Styrene, the material is a popular 3D printing material due to its low cost and good mechanical properties. These properties include commendable impact and wear resistance. It is the same plastic used in legos!
However, one print issue you are likely to encounter with ABS is that the material is susceptible to warping. Warping happens when the plastic cools from its extrusion temperature to room temperature, causing the plastic to shrink and contract. This can be particularly troublesome for the first layer, as this change in size can frequently cause the part to separate from the bed, thus ruining the print.
ABS A-100 is a subcategory of the usual ABS 3D printing material. Its properties are largely similar to the latter. However, warping rate and printing temperature for ABS A-100 is significantly reduced. Although ABS plastic is one of the most popular choices for 3D printing, it shrinks when it cools. This is especially so without a heated bed. The bottom of your print will cool at a different rate than the rest of your ABS print. This warping thus results in an undesirable print. With this enhanced ABS-A100 filament, you can bid goodbye to warping and expect a more accurate and precise print.
PLA is another popular FDM 3D printing material alongside ABS. Short for Polylactic Acid, it is a biodegradable vegetable based thermoplastic which commonly uses cornstarch as a raw material. In contrast to ABS, PLA tends to be less durable, more fragile, and more sensitive to heat. Its melting point is also relatively low at 150ºC. However, when cooling, this material contracts less than ABS. This makes it more resistant to warping and gives it good geometric stability during manufacturing. Hence, PLA is generally preferred for rapid prototyping where form is more critical than function.
ABS-ESD7 is a material that is able to prevent a buildup of static electricity. It can be used to produce end-use components, electronic products, industrial equipment and jigs and fixtures for assembly of electronic components. Due to its excellent static-dissipative properties, it is suitable for use in areas such as the semiconductor and electronics industry. Electronics manufacturers can expand the use of 3D printing onto the assembly line with this durable material that works with soluble support removal. This allows for the creation of complex parts with no extra effort.
Another variation of ABS, the ABS-M30 is up to 25% to 70% stronger than usual ABS. It is an ideal material for concept modeling, functional prototyping, manufacturing tools and production parts. The material has greater tensile, impact and flexural strength than standard ABS. Layer bonding is also stronger to produce a more durable part. ABS-M30 is able to produce higher quality end-use parts that are stronger, smoother, and have more feature detail.
