How do Protospeed 3D printers guarantee successful jewelry casting?

Protospeed castable resins are formulated with low ash content for a complete, clean burnout. This eliminates common casting defects like porosity and surface roughness. Every resin comes with proven burnout cycles tested across gold, silver, and platinum casting workflows so you get consistent results from day one.

Does printing at 65mm/hr reduce the quality or resolution of jewelry models?

No. Protospeed printers use an advanced DLP light engine with optimized print algorithms that maintain 50µm resolution even at maximum speed. You get production-scale throughput and the fine detail required for filigree, micro-prongs, and stone settings — without any compromise between speed and quality.

How long do the vats and projectors last on Protospeed jewelry 3D printers?

Protospeed Long Life Vats are rated for over 800 print jobs, eliminating the need for frequent replacements and platform recalibrations. The DLP projector is rated for 20,000 hours of continuous operation. Both components are engineered for professional production-floor use with minimal downtime and lower maintenance costs over the life of the machine.

3D Printers for Jewelry Casting

Q: Which Protospeed printer is best for a small jewelry workshop?

Magnus is the ideal entry-level DLP 3D printer for small jewelry workshops. It offers high resolution at 41–52 microns, a compact footprint, and class-leading speeds — making it an affordable and reliable starting point for direct casting production without a large upfront investment.

Q: What is the difference between Magnus, Rapid, and ProtoX?

Magnus is built for small-scale production and entry-level jewelry manufacturing. Rapid offers a larger build platform of 190 x 107 x 200mm and higher speeds for mid to high-production factories. ProtoX is the industrial workhorse with the largest platform in the lineup at 230 x 129 x 200mm, designed for maximum throughput and non-stop operation. All three use DLP technology and are fully compatible with Protospeed castable resins.

Protospeed makes three DLP 3D printers for jewelry casting: Magnus, Rapid and ProtoX. All three print up to 65 mm per hour at a 50 µm layer. They differ in platform size, from the compact Magnus for workshops starting out to ProtoX, the largest, for high-volume production.

The technology

Why DLP for Jewelry Casting?

A DLP printer cures each layer at once, so print time depends on job height—not the number of pieces. A full platform of rings takes about as long as one ring of the same height, delivering fast, consistent weight and gauge.

Whole layers: Full platforms, same time
50-30-20-10 µm layers: Filigree and stone settings
405 nm projector: Rated for 20,000 hours
Castable resins: Zero-ash burnout

All questions

Which Protospeed printer is best for a small jewelry workshop?

Magnus. It is the compact, entry-level printer in the range, with the same speed of up to 65 mm per hour at a 40 & 20 µm layer as the larger printers, so a workshop can start direct casting without a large machine.

What is the difference between Magnus, Rapid and ProtoX?

Platform size and output. Magnus is compact for small-scale work; Rapid adds a 190 × 107 × 200 mm platform (V1) for daily production; ProtoX has the largest, 230 × 129 × 200 mm, for maximum throughput. All three are DLP printers and use ProtoResins castable resins.

Which printer can print full casting trees and 200 mm bangles?

Rapid and ProtoX. Both have the 200 mm build height that full casting trees and 200 mm bangles need. Magnus, with a 112 mm build height, suits rings, pendants and shorter trees.

Does printing at 65 mm per hour reduce detail?

No as long as designs are properly supported. The figure is measured at a 50 µm layer, the layer used for fine detail such as filigree and prongs, so the speed and the detail come from the same setting. To give customers more freedom to choose speeds, Protospeed has provided multiple speed modes to choose from based on the type of jewelry and supporting styles.

What technology do Protospeed printers use?

DLP (digital light processing) with a 405 nm light source. The projector cures a whole layer at once, which is how all three printers reach up to 65 mm per hour at a 50 µm layer thickness.

How long do the vats and the projector last?

The aluminum long-life vat prints about 800 to 1,000 jobs and is refurbished by your authorized reseller to reduce cost to the customer. The refurbished tray functions as good as new. The DLP projector is rated for 20,000 hours of printing.

How much does a jewelry 3D printer cost?

It depends on the printer and the country, because duties and taxes vary. An authorised reseller, or Protospeed on WhatsApp, can quote you, and our 2026 cost guide breaks down printer, resin and running costs.
