FDM 3D Printing
in Australia

FDM stands for Fused Deposition Modelling. It is a 3D printing process that builds parts by melting plastic filament through a heated nozzle and depositing it layer by layer onto a build plate. Each layer bonds to the one below as it cools, forming the complete part from the bottom up. FDM is the most widely used 3D printing technology globally and in Australia, suited to functional parts, prototypes, educational models, jigs, fixtures, and batch component production.

FDM printers work with a wide range of plastic filaments. Common materials include PLA (easy to print, good surface finish), PETG (tough, moisture resistant), ABS (heat resistant, durable), ASA (UV stable, outdoor use), polycarbonate (high impact resistance, very high temperature tolerance), TPU (flexible), and carbon-fibre composites (stiff, lightweight). The materials an FDM printer can handle depend on its hotend temperature range and whether it has an enclosure. The Phrozen Arco has an all-metal hotend reaching 300 degrees C, which covers the full range of common FDM filaments.

FDM builds parts from plastic filament melted through a nozzle. Resin printing uses UV light to cure a liquid photopolymer resin. FDM excels at large-format parts, structural components, engineering-grade materials, and applications where material properties like toughness or heat resistance matter. Resin excels at fine surface detail, high XY resolution, and applications like dental models, jewellery casting masters, and miniature figures. FDM parts have visible layer lines. Resin parts have a smooth surface finish. 3D Cast stocks both FDM and resin 3D printing hardware and materials.

CoreXY is a motion system used in FDM printers where the print head moves in both X and Y while the build plate moves only in Z. On a standard bed-slinger printer, the build plate moves back and forth along the Y axis throughout the print, which adds mass and limits speed. CoreXY removes the build plate from the horizontal motion equation, allowing higher print speeds and better dimensional accuracy on large parts. The Phrozen Arco uses CoreXY and reaches a top speed of 600 mm/s across a 300 x 300 x 300 mm build volume.

Yes. FDM 3D printing is widely used in Australian secondary schools, TAFE colleges, and universities for design and technology, engineering, STEM, and manufacturing programs. FDM printers produce physical models, prototypes, and project components that students design in CAD software. The Phrozen Arco's automated calibration, Klipper firmware, and filament runout detection reduce the technical overhead in classroom and lab environments. 3D Cast supplies FDM hardware and filament to educational institutions across Australia.

Klipper is an open-source 3D printer firmware that runs on a separate computer rather than the printer's control board, giving it more processing power for real-time calculations. The key practical features are input shaping, which reduces vibration ringing artefacts at high speeds, and pressure advance, which improves corner sharpness. Both can be tuned to the specific material and speed being used. Klipper is used in the Phrozen Arco and gives users direct control over print parameters rather than fixed factory settings.

3D Cast stocks two Phrozen filaments designed for the Arco. Phrozen High Speed PLA is formulated for throughput at speeds up to 600 mm/s and is suited to general-purpose printing, batch production, and fast iteration prototypes. Phrozen Tough PLA is formulated for functional parts that need enhanced toughness and reduced breakage risk on fine features and load-bearing sections, printing at up to 200 mm/s. Both are 1.75 mm, 1 kg spools available in 8 colours. The Arco also prints PETG, ABS, ASA, polycarbonate, TPU, and carbon-fibre composites from third-party suppliers.

Most common FDM materials including PLA, PETG, and TPU do not require an enclosure. Engineering-grade materials including ABS, ASA, and polycarbonate benefit from an enclosed print environment because they are sensitive to ambient temperature variation and air currents, which cause warping and layer separation. The Phrozen Arco is an open-frame printer. For users printing ABS, ASA, or polycarbonate regularly, the Phrozen Penta Shield five-panel tempered glass enclosure is available from 3D Cast and fits directly to the Arco frame.

3D Cast is the official Australian distributor for Phrozen Technology and stocks the Phrozen Arco FDM printer along with High Speed PLA and Tough PLA filament. All hardware and filament ship from the 3D Cast warehouse in Bairnsdale, Victoria. Orders reach customers across every Australian state and territory without international shipping delays or customs complications. 3D Cast provides local technical support backed by people who run Phrozen hardware in-house.

The main ongoing cost in FDM 3D printing is filament. Phrozen High Speed PLA and Tough PLA are both $35 AUD per 1 kg spool from 3D Cast. A 1 kg spool produces approximately 300 to 500 average-sized parts depending on infill, size, and geometry. Other occasional costs include nozzle replacement, build plate replacement, and consumable items like PEI surface sheets. The Phrozen Arco's automated bed levelling and vibration calibration reduce the frequency of manual maintenance interventions.
