Why resin printing specifically suits jewellery and design work
Resin printing (MSLA — Masked Stereolithography) cures a liquid photopolymer resin layer by layer using a UV light source through a high-resolution LCD screen. The result is a surface quality and detail resolution that FDM printing physically cannot match at any price point.
The ELEGOO Saturn 4 Ultra 16K that we run at our Somerset West showroom has a 16K monochrome LCD. At this resolution, surface detail is measurable in microns — which means filigree patterns, facial features on figurines, fine text, and the tight tolerances required for jewellery casting models are all achievable in a single print without hand-finishing.
For jewellers and product designers specifically, this matters because the surface quality of the model directly affects the quality of the downstream result — whether that's a cast piece in metal, a moulded component in another material, or a presentation prototype shown to a client or investor.
What resin printing is used for in jewellery and design
Resin printing is widely used in jewellery design to produce highly accurate models for lost-wax casting. The resin model is used in place of a hand-carved wax, placed in an investment mould, and burned out during casting — leaving a cavity that is filled with metal. The surface finish and edge definition of a resin casting model eliminates much of the hand-finishing and polishing required before casting when using a hand-carved wax equivalent.
For intricate ring bands, pendant settings, earring components, and bracelet elements — particularly those with fine detail that is difficult to carve by hand — resin printing consistently produces better starting points than traditional wax carving at a fraction of the time.
Recommended resin: standard or castable resin depending on your casting process and metal
A resin prototype in a client's hands communicates surface quality, proportion, and fine detail in a way that a rendered image on a screen never does. For product designers working on small consumer goods, packaging components, or accessories, resin printing produces presentation-quality models that can be photographed, shown to investors, and used for client approval without the lead times and tooling costs of traditional prototyping.
The smooth surface of a resin print also means that painted or finished prototypes are achievable without the sanding and filling that FDM prints typically require before painting.
Recommended resin: ABS-like resin for durability, standard for visual prototypes requiring smooth surface only
Dental resin is biocompatible and dimensionally accurate — the two requirements that make it suitable for dental study models, orthodontic appliance bases, and diagnostic casts. For dental practices and prosthetists in the Western Cape exploring in-house resin printing, or requiring occasional models printed on demand, Toner and Ink stocks dental resin and can print from digital scan files or STL exports from dental software.
Recommended resin: dental resin — biocompatible, dimensionally stable
Architectural models requiring fine structural detail — columns, mouldings, decorative elements, facades at small scale — benefit from resin's ability to resolve features that FDM layer lines would obscure. For scale model makers, heritage documentation projects, and interior design presentations requiring physical models, resin delivers the detail level that makes the model credible at presentation scale.
Recommended resin: standard or ABS-like depending on whether the model will be handled or displayed only
Tabletop gaming miniatures, collectible figurines, and custom character models are one of the clearest demonstrations of what resin printing can do that FDM cannot. At miniature scale, FDM layer lines are visible to the naked eye and limit achievable detail on faces, weapons, and fine clothing. Resin at 16K resolution produces surface quality that approaches cast metal miniatures from traditional manufacturing — at a fraction of the cost and turnaround time.
Recommended resin: standard or ABS-like for standard miniatures; tough resin for gaming pieces that will be handled frequently
Which resin types do we stock and print in?
General-purpose resin suitable for most display, prototype, and casting model applications. Good surface finish, reliable dimensional accuracy. The most accessible and cost-effective option for jewellery models, presentation prototypes, and architectural components.
Tougher and more impact-resistant than standard resin. Suitable for prototypes that will be handled, tested, or used in a physical demonstration context. Less brittle than standard resin — the recommended choice when the printed part will be picked up, passed around, or used beyond static display.
Highest mechanical strength of the standard resin types. Suitable for functional resin components, prototypes that will undergo physical testing, and pieces requiring durability beyond what ABS-like delivers.
Cleaned with water rather than IPA solvent. Produces similar surface quality to standard resin with simpler post-processing. Suitable for most display and prototype applications where ease of cleanup is a consideration.
Biocompatible resin formulated for dental applications. Dimensionally stable and appropriate for dental study models, orthodontic appliance bases, and diagnostic casts. Requires biocompatibility certification — confirm your specific application requirements when enquiring.
Walk in before you commit. Our Somerset West showroom has the Saturn 4 Ultra 16K running with finished resin prints on display. Hold a resin jewellery model in your hand before deciding whether the technology suits your process — that 10-minute visit answers most questions more definitively than any specification document.
