When it comes to 3D printing with Fused Deposition Modeling (FDM) technology, choosing the right filament is crucial for achieving the best results. At The Goods Store, we specialize in a variety of FDM filaments, each with its own set of advantages and ideal applications. Whether you're a seasoned maker or just starting your 3D printing journey in New Zealand, understanding the pros and cons of each filament type will help you make informed decisions for your projects.
PLA (Polylactic Acid)
PLA is the go-to filament for many 3D printing enthusiasts due to its ease of use and eco-friendly properties. Made from renewable resources such as cornstarch and sugarcane, PLA is biodegradable and has a minimal environmental impact compared to petroleum-based plastics. This makes it a popular choice for those who prioritize sustainability.
Environmental Impact: Low. PLA is made from renewable resources and is biodegradable under industrial composting conditions.
Printing Difficulty: 1/5. PLA is very forgiving and easy to print, making it ideal for beginners. It has low warping and requires no heated bed.
Cost of Material: 1/5. PLA is one of the most affordable 3D printing filaments available.
Printing Service Cost: 1/5.
Print Quality: PLA prints typically have a smooth surface finish with good dimensional accuracy. However, it is less suited for high-strength applications due to its brittleness.
Ideal Uses: Home decor items, prototypes, educational projects, and toys.
Real-World Common Occurrences:
- LEGO Bricks: The material of choice for LEGO bricks due to its strength and durability.
- Automotive Parts: Used in various automotive parts like dashboards, wheel covers, and other interior components.
- Household Appliances: Found in the casing of household appliances such as vacuum cleaners, kitchen appliances, and electronic housings.
- Musical Instruments: Utilized in the manufacturing of certain musical instruments, like recorder flutes.
- Sports Equipment: Common in protective sports gear, helmets, and other durable sports equipment.
PETG (Polyethylene Terephthalate Glycol)
PETG is a versatile filament that combines the strength of ABS with the ease of printing of PLA. It is known for its durability, chemical resistance, and flexibility, making it suitable for a wide range of applications. 3D printing giant Prusa uses PETG to 3D print parts for their own printers due to these reasons, as well as for its excellent layer adhesion and minimal warping, ensuring their printers are both reliable and high-performing.
Environmental Impact: Moderate. PETG is not biodegradable but is recyclable, making it a better option than ABS from an environmental perspective.
Printing Difficulty: 3/5. PETG requires careful calibration to avoid stringing and ensure good adhesion. It benefits from a heated bed.
Cost of Material: 2/5. PETG is slightly more expensive than PLA but still affordable.
Printing Service Cost: 3/5.
Print Quality: PETG offers a good balance between flexibility and rigidity, with excellent layer adhesion and resistance to warping. However, it can sometimes have issues with stringing, leading to a slightly inconsistent surface finish.
Ideal Uses: Functional parts, outdoor items, and food containers (when printed properly).
Real-World Common Occurrences:
- Water Bottles: Used in the production of reusable water bottles due to its durability and chemical resistance.
- Food Containers: Common in food storage containers that require a balance of flexibility and strength.
- Medical Devices: Utilized in some medical devices and packaging due to its chemical resistance and clarity.
- Protective Cases: Found in phone cases, laptop covers, and other protective gear for electronics.
- Signage: Often used in signage and displays that need to withstand outdoor conditions.
ABS (Acrylonitrile Butadiene Styrene)
ABS is a durable and heat-resistant filament commonly used in industrial applications. It is known for its strength and impact resistance, making it suitable for functional prototypes and end-use parts.
Environmental Impact: High. ABS is petroleum-based and not biodegradable, contributing to plastic pollution.
Printing Difficulty: 4/5. ABS requires a heated bed and controlled environment to prevent warping and maintain dimensional accuracy.
Cost of Material: 2/5. ABS is relatively inexpensive but slightly more costly than PLA.
Printing Service Cost: 4/5.
Print Quality: ABS provides strong, durable prints but is prone to warping and shrinkage. Proper ventilation is necessary due to the strong fumes emitted during printing.
Ideal Uses: Functional prototypes, enclosures, and durable toys.
Real-World Common Occurrences:
- LEGO Bricks: The material of choice for LEGO bricks due to its strength and durability.
- Automotive Parts: Used in various automotive parts like dashboards, wheel covers, and other interior components.
- Household Appliances: Found in the casing of household appliances such as vacuum cleaners, kitchen appliances, and electronic housings.
- Musical Instruments: Utilized in the manufacturing of certain musical instruments, like recorder flutes.
- Sports Equipment: Common in protective sports gear, helmets, and other durable sports equipment.
TPU (Thermoplastic Polyurethane)
TPU is a flexible filament known for its elasticity and abrasion resistance. It is ideal for applications that require parts to bend or stretch without breaking.
Environmental Impact: Moderate. TPU is not biodegradable but is more durable and long-lasting, potentially reducing the need for frequent replacements.
Printing Difficulty: 5/5. TPU requires precise tuning and slower print speeds to achieve good results. It can be challenging to print due to its flexibility.
Cost of Material: 3/5. TPU is more expensive than PLA and PETG.
Printing Service Cost: 4/5.
Print Quality: TPU prints can have an inconsistent surface finish due to its rubbery nature. It offers excellent flexibility and abrasion resistance, but achieving precise dimensional accuracy can be difficult.
Ideal Uses: Wearables, flexible automotive parts, and sports equipment.
Real-World Common Occurrences:
- Shoe Soles: Used extensively in the manufacturing of flexible and durable shoe soles, especially for athletic footwear.
- Phone Cases: Popular in flexible and shock-absorbing phone cases and tablet covers.
- Wearable Devices: Found in the bands of smartwatches and fitness trackers due to its flexibility and comfort.
- Medical Devices: Used in some flexible medical tubing and devices.
- Automotive Parts: Utilized in automotive seals, gaskets, and other components that require flexibility and durability.
