Everything you need
to print in resin

Resin 3D printing is an additive manufacturing process that uses a UV light source to cure liquid photopolymer resin into solid parts, one layer at a time. The most common desktop format is MSLA (Masked Stereolithography), which uses a monochrome LCD panel to define each layer. MSLA resin printing produces parts with smooth surfaces, fine detail, and dimensional accuracy that FDM filament printing cannot replicate.

FDM printers extrude melted filament to build parts layer by layer, producing visible layer lines and a rougher surface finish. Resin MSLA printers cure liquid resin using UV light, producing much smoother surfaces and finer detail at the cost of requiring post-processing. Resin printing is suited to applications where surface accuracy and detail are the priority. FDM is better suited to larger structural parts where surface finish is less critical.

MSLA stands for Masked Stereolithography Apparatus. It is the most common resin 3D printing format for desktop printers. MSLA printers use a monochrome LCD panel as a mask between a UV light source and the resin vat. The LCD exposes only the areas of each layer that should cure, building the part from the bottom up one layer at a time.

XY resolution refers to the pixel size of the LCD panel, measured in microns. It determines how fine the horizontal detail in a print can be. A smaller pixel size means finer detail. For example, the Phrozen Sonic Mighty 12K has an XY resolution of 19 × 24 µm and the Phrozen Revo 16K has an XY resolution of 14 × 19 µm. Z resolution, which determines layer thickness, is set in the slicing software and is typically between 25 and 100 µm.

Resin prints require two post-processing steps after leaving the printer. First, washing removes uncured liquid resin from the surface using isopropyl alcohol or a dedicated wash solution such as Monocure3D Resinaway. Second, curing exposes the washed print to UV light to fully harden the photopolymer. A dedicated wash and cure station automates both steps and produces more consistent results than manual processing.

Liquid photopolymer resin is a chemical irritant and should be handled with appropriate safety precautions. Nitrile gloves, eye protection, and ventilation are recommended when operating a resin printer, handling the vat, or performing post-processing. Cured resin is generally considered inert and safe to handle without gloves. Safety data sheets for all resins stocked by 3D Cast are available on request.

Phrozen MSLA printers are compatible with Phrozen's full resin range and any third-party 405 nm photopolymer resin. 3D Cast stocks standard, high-resolution, engineering, and castable resin formulations from Phrozen, Monocure3D, and Resione, all available from Australian stock.

3D Cast is the official Australian distributor for Phrozen Technology and stocks MSLA resin printers from Australian stock, shipping from Bairnsdale, Victoria. The Phrozen Sonic Mini 8KS, Sonic Mega 8K S, Sonic Mighty 12K, and Revo 16K are all available with full manufacturer warranty and local distributor support.

Phrozen offers five MSLA resin printers stocked in Australia through 3D Cast, covering compact desktop to large-format production printing. The Phrozen Sonic Mini 8KS is a compact 7.1 inch desktop printer at 8K resolution, suited to miniature painters and hobbyists who prioritise a small footprint. The Phrozen Sonic Mega 8K S is a large-format 11.5 inch printer at 8K resolution suited to studios and batch production runs. The Phrozen Sonic Mighty 12K is a mid-sized 10 inch printer at 12K resolution and 19 × 24 µm XY resolution with a 218 × 123 × 235 mm build volume and built-in camera for remote monitoring. The Phrozen Revo 16K steps up to 16K resolution at 14 × 19 µm with auto bed levelling and auto plate calibration, suited to applications requiring finer resolution and automated calibration. The Phrozen Sonic Mighty Revo 16K MAX is the flagship large-format 16K printer suited to studios running large-format high-resolution work, currently available via waitlist.

3D Cast provides pre-sale advice, setup guidance, and ongoing support for all Phrozen printers sold through the store. As the official Australian distributor, 3D Cast can assist with warranty queries and stocks genuine Phrozen spare parts from Australian stock. Some replacement parts are sourced from the Phrozen factory and shipped from overseas.
