Over 30 key terms from the world of jewelry, 3D printing, laser engraving, and resin casting, explained simply and concisely, with links to related tools.
Creating precise 3D models in Rhino and Fusion 360 - both organic jewelry forms and functional technical parts (parametric design, mechanical tolerances, reverse engineering). AEJaCA models from a sketch, photo, or idea, preparing files ready for 3D printing or casting.
An alloy of 92.5% pure silver and 7.5% copper. The standard for AEJaCA jewelry - durable, hypoallergenic, and easy to polish.
Using artificial intelligence to generate concepts, textures, and patterns - accelerating the AEJaCA design process.
Read the article βSoftware for creating precise 2D/3D models (Fusion 360, Blender, Rhino). A CAD file is the starting point for 3D printing or CNC.
Read the article βA resin for MSLA printing designed to burn out cleanly in a casting kiln. AEJaCA uses BlueCast X-One V2 (zero shrinkage, for shanks and bulky elements) and BlueCast X-Wax Filigree (over 80% wax content, for filigree and details down to 0.2 mm). High wax content ensures complete combustion with no ash residue, protecting the casting mold.
The casting comes out smaller than the pattern, because an alloy takes up less room solid than liquid. How much depends on the alloy: silver 925 shrinks about 1.6 percent, 9K gold about 2.1. That is why the model is enlarged before printing, not corrected after casting.
Scaling up a CAD model before printing by a factor matching the alloy's shrinkage during solidification, so the finished casting reaches its target size. AEJaCA applies: Au 585 x1.0196, Ag 925 x1.016, Au 9K x1.021, Au 18K x1.018. Without this correction, the casting comes out smaller than the designed model.
The way links are joined, which decides how a chain looks, how it lasts and what it costs. It is described by the weave factor: how much wire goes into one centimetre of finished chain. A classic weave is x1.0, a Byzantine x3.2, so the same length costs three times more.
A gas laser (10.6 ΞΌm) for cutting and engraving wood, leather, acrylic, glass. Available at AEJaCA sTuDiO with instant online pricing.
A ring given at a proposal - typically set with a diamond, moissanite, or gemstone. AEJaCA designs them to order.
Layer-by-layer printing from melted filament (PLA, PETG, ABS). An economical option for prototypes and functional parts at AEJaCA sTuDiO.
A fiber laser (1064 nm) for precision metal marking - steel, aluminum, silver, gold. Permanent markings and jewelry engraving.
A natural mineral valued for hardness, clarity, and color (diamond, ruby, sapphire, emerald). Used in AEJaCA rings and pendants.
14k (585) contains 58.5% gold - durable for everyday wear. 18k (750) is 75% gold - richer color, ideal for engagement rings.
Gold or platinum jewelry with gemstones that retains or appreciates in value over time. What drives that value is the metal, the quality of the stone and the workmanship.
Pure gold and silver are too soft for jewelry, so they are alloyed with copper, zinc, silver or palladium. The additions set hardness, colour and melting point: copper pulls the tone red, palladium white, zinc improves how the metal fills a mould when cast.
A casting method where a pattern printed in castable resin is invested in casting plaster, then burned out in a kiln at around 600Β°C so the resin combusts cleanly, leaving an empty cavity ready for metal. AEJaCA uses this pattern to cast rings and figurines in 925 silver or 585 gold.
A synthetic mineral (SiC) with diamond-like brilliance at a fraction of the cost. Mohs hardness 9.25.
A resin printing technology where an entire layer is cured at once by UV light projected through a mono LCD screen, rather than point-by-point as in classic laser SLA. Resolution depends on the screen's pixel size (14x19 Β΅m on the Elegoo Saturn 4 Ultra 16K), not on nozzle diameter as with FDM. It produces a smooth surface and detail from about 0.2 mm, far finer than FDM's 0.4-0.8 mm.

Tailoring a product to individual needs - engraving, color, size, material. A key AEJaCA service across jewelry and studio.
Read the article βText, date, or symbol engraved inside a band or on a pendant. AEJaCA offers both fiber laser and hand engraving.
A tough filament resistant to impact and chemicals, less brittle than PLA and easier to print than ABS. For mechanical parts and components that work outdoors.
Biodegradable corn-based filament - the most popular 3D printing material. Easy to print, available in many colors.
Rapidly creating a physical model before serial production. 3D printing at AEJaCA sTuDiO lets you validate a design in hours.
Casting parts from epoxy or polyurethane resin in silicone molds. AEJaCA offers transparent and tinted castings.
Electroplating silver or white gold with a thin layer of rhodium. It increases shine and tarnish resistance, wears off in time and then has to be redone.
The inner diameter of a ring in mm. AEJaCA helps you measure your size remotely - just ask via the contact form.
Standard 3D format (triangle mesh) used in 3D printing. The AEJaCA calculator accepts STL files and quotes instantly.
A vector graphics format used for laser cutting and engraving. The AEJaCA calculator reads SVG dimensions and quotes instantly.
Liquid resin cured by UV light - produces very smooth, high-resolution prints. Used for jewelry models and fine details.
A pair of rings exchanged during the wedding ceremony. At AEJaCA you can personalize them with engraving, texture, and profile.
