What is PLA Filament? Understanding the Basics
PLA filament is derived from renewable plant starches like corn starch or sugarcane, making it one of the most accessible materials in 3D printing. It is renowned for its straightforward handling, making it the reliable choice for newcomers and a daily staple for makers.
Here is why PLA remains so popular on Australian workbenches:
- Ease of printing: With our recommended print settings running at a nozzle temperature of 190–220°C and a heated bed between 40–60°C, PLA minimises warping and bed adhesion headaches. That means less time troubleshooting and more successful prints straight off the build plate.
- Low odour: Unlike traditional materials such as ABS filament, PLA produces very little odour during extrusion, making it much more pleasant for home workshops and shared family areas.
- Crisp detail and finish: A standard spool yields clean layer lines, smooth surfaces, and sharp definition, which suits display models, rapid prototypes, and decorative parts.
- Versatile application: From tabletop terrain and desk organisers to dimensionally accurate test fits, standard 1.75 mm PLA handles a broad spectrum of hobby projects.
When searching for the best PLA filament for beginners, starting with a consistent, standard formulation is the most reliable way to get comfortable with your printer setup.
Deciphering PLA Filament Types: Standard, Enhanced & Specialised Filaments
When searching for filament, you will encounter various terms and designations. Understanding these different PLA filament types is crucial to making an informed decision for your upcoming print projects.
Standard PLA
This is your everyday PLA—reliable, easy to print, and available in a vast spectrum of colours. It is perfect for general prototyping, display models, and any project where extreme mechanical strength is not strictly required.
Enhanced PLAs (Addressing PLA+, PLA 2.0, PLA Pro, etc.)
You have likely seen labels like PLA+, PLA 2.0, or PLA Pro. These names often imply improved impact resistance, smoother flow, or higher durability. While some manufacturers tweak formulas with modifiers, other brands use these labels purely as marketing tags. The actual performance differences vary widely across suppliers.
When running a formulation like PLA 2.0, standard printing parameters generally call for a nozzle temperature between 190–220°C and a heated bed between 40–60°C, using reliable 1.75 mm spools with tight ±0.02 mm tolerances.
We focus on tight dimensional accuracy, smooth extrusion, and rich colours. When you choose PLA filament, picking consistent raw material matters far more than a fancy suffix on the spool label.
Aesthetic PLA Filaments
Beyond flat colours, a range of visually striking options allows you to enhance your print finishes without post-processing:
- Silk PLA: Delivers a glossy, pearlescent finish that catches the light cleanly. It works brilliantly on display pieces, decorative vases, and figurines. A clean spool of PLA Silk White is a great example of this smooth sheen.
- Matte PLA: Offers a non-reflective, low-sheen finish that helps mask visible layer lines for a clean, professional look.
- Glitter or Sparkle PLA: Infused with fine reflective flecks to disperse light across the surface of the print.
- Translucent PLA: Lets light pass through perimeter walls, making it ideal for lithophanes, lampshades, and light diffusers.
- Glow-in-the-Dark PLA: Charges under ambient light or UV and glows in darkness, creating eye-catching novelty prints.
Composite PLA Filaments
Composite materials blend a standard base polymer with fine particles to give finished prints unique mechanical properties or distinct textures:
- Wood PLA: Formulated with organic wood particles, giving models an earthy appearance and tactile feel that can be lightly sanded.
- Metal-filled PLA: Loaded with fine metal powder to add physical weight, allowing parts to be buffed for a metallic look.
- Carbon Fibre PLA: Blended with chopped carbon strands to boost structural rigidity and minimise flex. Note that abrasive additives cause rapid wear on standard brass nozzles, so a hardened steel nozzle is recommended.
- Marble-look PLA: Uses contrasting specks suspended in a neutral base to create the visual texture of cut stone.
How to Choose the Best PLA Filament for Your Printer and Projects
Choosing the right spool isn't just about picking a shade; it is about matching the material to your setup and print goals. Here are the key factors to consider:
1. Filament Diameter and Tolerance
Most desktop 3D printers use 1.75 mm filament, though some older machines take 2.85 mm. Check your printer's specifications before ordering so you do not end up with the wrong size.
Tight dimensional accuracy is vital for smooth feeding. Aim for a tolerance of ±0.02 mm to avoid issues like under-extrusion, over-extrusion, or sudden nozzle clogs during long print jobs.
2. Spool Size and Storage
Standard spools generally come in 1 kg weights, but you can also find smaller test rolls or bulk options. Larger spools keep you running through big builds, while smaller rolls let you sample distinct finishes without leftover stock sitting around.
PLA absorbs moisture from ambient air over time. Proper filament storage using a sealed container or vacuum bag with desiccant helps prevent stringing, brittle strands, and rough layer lines.
3. Project Requirements
- Strength and durability: For everyday mechanical parts, quality standard PLA filament performs well. However, if your print needs higher impact strength or temperature resistance, consider switching to PETG or robust ASA.
- Aesthetic finish: For display models and decorative pieces, try specialised surface textures like silk PLA for a high-shine sheen, or matte PLA to help hide visible layer lines.
- Flexibility: PLA remains a rigid thermoplastic. If your model needs to bend, compress, or absorb vibration, opt for flexible TPU instead.
- Outdoor durability: Standard PLA can warp under the Australian summer sun. For outdoor UV resistance and weather exposure, materials like ASA are far better suited.
Essential 3D Printer Filament Buying Tips for Quality Prints
Beyond the type of PLA, there are general filament buying tips that apply across the board to ensure you get reliable results and a smooth printing experience:
- Brand reputation and reviews: A reputable brand invests in quality control, consistent manufacturing, and reliable support. Look for brands with positive reviews regarding filament consistency, colour accuracy, and customer service.
- Packaging: Ensure the spool arrives sealed in a vacuum-packed bag with a desiccant packet. This helps protect the material from ambient moisture before it reaches your printer.
- Price versus quality: While budget options are tempting, extremely low-cost rolls often cut corners on manufacturing tolerances. Inconsistent diameters and poor winding lead to clogs and failed prints. Investing in consistent quality control saves headaches, time, and wasted material over time.
- Spool winding: Poorly wound spools can cause snags and tangles mid-print, stopping extrusion entirely. Look for cleanly wound spools to ensure seamless unspooling during long print jobs.
- Sample packs: If available, testing small sample coils is a practical way to check print behaviour and colour finish before committing to a full 1 kg spool.
Optimising Your Prints: Getting the Best Out of Your PLA Filament
Even quality material needs dialled-in print settings to shine. Here are some practical tips to optimise your PLA prints:
- Nozzle temperature: We recommend running between 190°C and 220°C for our PLA filament range. If you run into stringing, drop the temperature slightly. If layer adhesion looks weak, bump it up a few degrees.
- Bed temperature: A heated bed helps keep your base flat and prevents warping. Aim for 40°C to 60°C. Surfaces like smooth PEI sheets, textured plates, or a light coat of glue stick will help lock your parts down.
- Print speed: Start at a moderate pace to check flow before speeding things up. Push the speed gradually once you know your hotend can keep up without under-extruding.
- Part cooling: PLA loves strong airflow. Running your cooling fan after the initial layers helps set fine details, bridge gaps cleanly, and maintain sharp overhangs.
- Retraction settings: Setting your retraction distance and speed correctly stops stray oozing as the nozzle travels across open gaps.
- First layer calibration: Level your build plate and set a proper Z-offset so the first layer lays down flat with a consistent bead.
Frequently Asked Questions
Is PLA environmentally friendly?
PLA is derived from renewable resources like corn starch or sugarcane, giving it a lower carbon footprint during production compared to petroleum-based plastics. While it breaks down in dedicated industrial composting setups, it does not degrade quickly in a standard home compost bin.
What's the difference between PLA and PETG?
PLA is easier to print, delivers sharp aesthetic detail, and works reliably with minimal warping. PETG offers greater impact resistance and withstands higher operating temperatures, making it a solid upgrade for functional outdoor or mechanical parts, though it can require higher hotend temperatures and careful tuning to avoid stringing.
Can I paint PLA prints?
Yes, PLA accepts paints very well, including standard hobby acrylics and plastic-compatible spray paints. For a durable, smooth finish, lightly sand the surfaces, apply a plastic primer, and finish with your chosen paint and a protective clear coat.
How long does PLA filament last on the shelf?
When stored properly, PLA filament easily lasts for twelve months or longer. Keep your rolls in sealed, airtight containers or vacuum bags with desiccant packets to prevent ambient moisture from causing brittle filament, bubbling, and poor layer bonding.
