Welcome to our Material Guide, where we help make sense of the myriad materials available in 3D printing! The material you choose determines the physical properties of your final product, and understanding each material's capabilities can elevate your designs from good to outstanding.
PLA (Polylactic Acid)
One of the most commonly used materials in 3D printing, PLA, is a biodegradable plastic derived from renewable resources like corn starch or sugar cane. Known for its easy-to-use nature, PLA offers an excellent print quality, making it a popular choice for beginners and hobbyists. However, keep in mind that PLA isn't very heat-resistant or strong, which makes it less suitable for mechanical parts or products exposed to the sun or high temperatures.
ABS (Acrylonitrile Butadiene Styrene) ABS is a strong, flexible plastic widely used in 3D printing. Known for its high durability and heat resistance, ABS is a favorite for creating parts that require toughness and resilience, such as protective components, tools, and toys. However, it can produce fumes during printing, so a well-ventilated space is necessary. ABS also requires a heated bed for optimal printing conditions.
PETG (Polyethylene Terephthalate Glycol-modified) PETG combines the ease of use of PLA with the strength and durability of ABS. It's known for its robustness, flexibility, and temperature resistance. In addition, PETG is highly resistant to water and many chemicals, which makes it a preferred choice for outdoor and mechanical parts. It's also food-safe, so it's often used in the production of containers for food and beverage storage.
TPU (Thermoplastic Polyurethane) If you're looking to print flexible parts, TPU is the go-to material. It's highly flexible and extremely tough, often used in products that require bendability and resilience, like phone cases, shoes, and medical devices. It's not only my favorite filament, my puppies love it! Because TPU it is food safe, we make some pretty cool chew toys! However, TPU can be challenging to print due to its flexibility, and it's hydrophilic properties, so it requires a more experienced hand and Controlled settings.
Nylon (Polyamide) Nylon is a strong, lightweight material with excellent wear resistance, making it perfect for functional parts like gears and bearings. It's also semi-flexible, so it's ideal for parts that need to have some give. One important thing to note is that Nylon absorbs moisture, which means it's hydrophilic and needs to be stored correctly. Also, the printing environment must be temperature and humidity controlled.
Resins Used in Stereolithography (SLA) and Digital Light Processing (DLP) 3D printing technologies, resins allow for extremely high-detail prints. They're ideal for miniatures, jewelry, and dental and medical models. Resins come in various types, including standard, tough, flexible, and castable, each with different properties.
In conclusion, the selection of your 3D printing material depends on the specific requirements of your project. Whether you're printing a decorative piece or a functional part, understanding the strengths and weaknesses of each material can help you achieve the best result.
