How to choose 3D printer filament

Choosing filament comes down to two questions. What does the part need to do: look good on a shelf, bend, survive a hot car, carry a load or resist wear? And what can your printer handle: its maximum nozzle and bed temperatures, whether it has an enclosure, and whether it has a hardened nozzle for abrasive fibre-filled materials? Match the answers and the shortlist gets short quickly.

Use the table below to find your material family, then open that collection for individual grades, print settings and troubleshooting. If you would rather be guided, our Filament Finder tool can help narrow it down.

Nozzle ranges come from our product data and vary by grade within each family, so always check the product page. ABS, ASA, polycarbonate and nylon give off more fumes than PLA and dislike draughts, so print them in an enclosure in a well-ventilated room. For demanding heat, load or chemical requirements, our engineering filament range brings nylon, polycarbonate, PET-CF, PPA-CF and PPS-CF together.

Speciality finishes and colour effects

Most decorative filaments are built on PLA, so they print nearly as easily as a standard roll. In the PLA range you will find Silk PLA for a high shine, Matte PLA for a soft finish that hides layer lines, glow in the dark options, and Wood, Marble, Metal and Glitter blends for texture. For several colours from one spool, including gradient rainbow, dual and tri-colour silk, chameleon and heat reactive colour change, browse multi-colour and rainbow PLA. If a decorative part also needs to be tough, look at Sparkling and Chameleon ASA, ABS+ Sparkling or Metallic PETG-HS.

Why 1.75mm, and what tolerance means

Every filament in this collection is 1.75mm, the diameter used by most current desktop printers. Check your printer's specifications before ordering, because a machine designed for 2.85mm filament cannot feed 1.75mm. Tolerance describes how far the diameter may vary along the roll. Your slicer assumes a constant diameter, so thicker or thinner sections change how much plastic is pushed out, which shows up as blobs, gaps or weak spots.

We list tolerance per product rather than across the range. Silk PLA and PETG+ Transparent list ±0.03mm, for example, while PLA-CF, PETG-CF, HIPS and PVA list ±0.05mm. Check the product page or data sheet for the figure on any roll you are considering.

Filament in Australian heat and humidity

Heat is the problem after printing. PLA+ lists a heat deflection temperature of 53°C, so a part left on a dashboard or in a tin shed over summer can soften and warp. PETG+ lists 68°C, ABS+ 85°C, ASA 88°C and polycarbonate 123°C, which is why the table steers hot and outdoor parts away from PLA. Our heat deflection temperature chart compares the wider range.

Moisture is the problem before printing. Filament absorbs water from humid air, and damp filament strings, pops at the nozzle and prints weaker layers. Nylon, PVA, TPU and PETG are the most sensitive, and humid coastal summers make things worse.

Most of our spools arrive vacuum sealed with desiccant. Once a roll is open, keep it in a vacuum bag with desiccant and dry it before printing if it has been left out. Drying needs vary widely, from 40-45°C for 4-6 hours for PLA+ to at least 5 hours at 80°C for ABS and ASA, and at least 12 hours at 80°C for PA6 and PA12 nylon grades.

Buying 3D printer filament from OzFDM

Volume pricing applies in your cart on 1kg rolls, and any colours and materials count toward each tier: 3 or more rolls save 5%, 6 or more save 10%, 12 or more save 15%, and a full carton of 12 rolls in the same colour and material saves 20%. Once your order tops $299 after discounts, delivery is free Australia-wide (PO Boxes excluded), with dispatch from our Perth and Melbourne warehouses. Schools, businesses and print farms can apply for a trade account, and our value packs bundle colour sets and storage refills.

3D printer filament FAQs

Which filament should a beginner start with?

Start with PLA+. It prints at 190-220°C on a 25-60°C bed, needs no enclosure and is forgiving while you learn bed levelling and slicer settings. Once your prints are reliable, PETG is the natural next step for tougher functional parts. Leave nylon, polycarbonate and fibre-filled materials until your printer and experience are ready. Our guide to choosing a filament type for your project can also help.

Will your filament work in my printer?

If your printer takes 1.75mm filament and reaches the nozzle and bed temperatures listed on the product page, it can print that material. Abrasive carbon and glass fibre grades also need a hardened nozzle, and ABS, ASA, PC and nylon print best in an enclosure. If you run an automatic material system, check the product page first, as compatibility notes vary by product and spool size.

What is the best filament for outdoor parts in the Australian sun?

ASA. Its product data highlights UV and weather resistance and lists an 88°C heat deflection temperature, which makes it our first choice for car accessories, garden fittings and outdoor mounts. PETG handles more heat than PLA and suits shaded outdoor jobs. PLA should stay indoors, because it can soften at around 53°C.

Can I mix colours and materials to get volume pricing?

Yes. Every 1kg roll in your order counts toward the tiers, whatever its colour or material. Two rolls each of PLA+, PETG+ and ASA make six rolls, which reaches the 10% tier. The 20% tier is the one exception, because it needs a full carton of 12 rolls in the same colour and material.

How should I store filament in a humid climate?

Keep new spools sealed until you need them. After each session, return open rolls to a vacuum bag with fresh desiccant, or print from a dry box. A small hygrometer inside the bag or box shows when the desiccant needs replacing. If a roll starts stringing or popping, dry it at the temperature on its product page before printing again.

Do I need a hardened nozzle?

Only for abrasive filaments. Carbon and glass fibre are abrasive and wear standard brass nozzles, so use a hardened nozzle for fibre-filled grades, and the PETG-ESD listing recommends one too. Unfilled PLA, PETG, ABS, ASA and TPU print happily through brass. Check your printer's maximum nozzle temperature as well, because some engineering grades such as PPS-CF run above 300°C.
