Overview

Midas is SprintRay’s chairside 3D printing system designed to fabricate high-quality dental restorations using single-use resin capsules. This article introduces the Midas printer, the included components, and foundational concepts for new users. Detailed setup, printing, and maintenance instructions are provided in the following articles.

Key Components

Print Arm

The print arm is the only moving mechanism within Midas. It lowers during printing and raises upon completion. The arm should not be touched while the printer is operating.

Cartridge Template

• The cartridge template ensures accurate placement of resin capsules.
• Position the template on the print glass following the alignment indicators
• Confirm that it sits level and does not shift
• Remove the template when cleaning the print glass
• Do not begin a print without the template installed

Barcode Scanner

The barcode scanner verifies capsule type, shade, expiration date, and other critical information. Each capsule must be scanned prior to placement.

Midas Capsules

Midas uses a single-use resin capsule system instead of traditional resin tanks, bottles, or reusable build platforms. Each capsule contains the material needed for a single restoration, packaged in a sealed and controlled format.

This design eliminates resin handling, reduces maintenance, and simplifies restorative 3D printing. Capsules remain sealed until use, minimizing exposure to resin and reducing the chance of contamination or variability.

Capsules are available in multiple materials and shades to support a range of chairside applications, including crowns, inlays, onlays, veneers, and other definitive restorations

How Midas Prints

Midas utilizes SprintRay's Digital Press Stereolithography (DPS), a method that enables the printing of highly filled restorative materials with consistent accuracy. The printing sequence includes the following steps:

1. Scan — Capsule material and shade information are verified
2. Place — The printer guides correct slot placement on the heated print glass
3. Press — Midas performs the automated press-and-cure cycle
4. Remove — The capsule is removed, and the restoration is transferred to post-processing

This controlled process minimizes variability and provides rapid chairside production.
