SLA 750

High-Speed Stereolithography Solution for Production Manufacturing

Production-Grade SLA Workflow Solution

The SLA 750 solution delivers a breakthrough in additive manufacturing productivity, speed, reliability, and automation from the leading innovator in stereolithography (SLA) 3D printing. A full solution is comprised of the SLA 750 family of large-format 3D printing systems, advanced production-grade photopolymer materials, the PostCure 1050 post-processing system, and the Oqton cloud-based, end-to-end manufacturing operation system.

Large Production Parts at High Speeds

From the original inventor of SLA and the innovation leader in production-grade photopolymer technology, 3D Systems introduces the industry’s fastest SLA 3D printers: The SLA 750 and the SLA 750 Dual.

The SLA 750 Dual is the world’s first synchronous dual-laser SLA printer delivering up to twice the speed and triple the throughput of current SLA printers, using dual imaging systems together with a proprietary scan algorithm, Hyper-Scan™ vector technology, developed especially for efficient, high-quality production manufacturing.

The single-laser SLA 750 is field upgradeable to the dual-laser SLA 750 Dual, allowing you to rapidly scale productivity with increased demand.

Optimized Laser Scanning Technology

Unlike conventional SLA 3D printers that use off-the-shelf scanning technology, the SLA 750 and SLA 750 Dual use a proprietary scanning algorithm developed for the unique needs of production additive manufacturing. Hyper-Scan™ vector technology optimizes key speed and productivity elements to answer the needs of high demand applications and manufacturing environments.

Fleet Automation Readiness with 24/7 Lights-Out Operation

The SLA 750 and SLA 750 Dual come with downstream automation readiness and robot-compatibility for 24/7 lights-out operation including fully automatic printer turnover with job off-loading, washing, and on-boarding. Both 3D printers come with a robot accessible chamber handle, fixed START and STOP buttons​, robot cycle start controls similar to existing CNC machines, automatic bottle or bulk material feed and connectivity ports​.

Industrial-Scale Post-Processing with PostCure™ 1050

PostCure 1050 is an industrial-scale post-processing system with up to 10 times higher throughput compared to current similar systems, including high volume, high-speed drying and curing for batch jobs and large parts up to 1050 x 750 x 600mm. Featuring optimized light wavelengths, a separately configurable UV intensity, and actively cooled LEDs with separately adjustable heating, you can now ensure optimal part curing without incurring unwanted thermally induced warp in your printed parts.

Factory Floor Integration, Management, and Control

The SLA 750 uses Oqton’s best-in-class, cloud-based, AI-powered Manufacturing OS that unifies engineering and production through IoT and machine learning to solve manufacturing challenges across industries. Oqton’s Manufacturing OS seamlessly integrates additive manufacturing with your factory floor equipment and allows you to schedule your production and post-production processes for efficient machine utilization, as well as connect machines to enable full traceability and valuable data insights.

End-to-End File to Print Software

The SLA 750 uses 3D Sprint, an advanced, single-interface software for file preparation, editing, printing, and management. Quickly and efficiently go from design to high quality, true-to-CAD parts without needing additional third-party software. 3D Sprint is optimized for production environments with the latest time-saving workflows, UI, and UX to maximize printer capacity and build volume utilization for batch run jobs.

A New Standard for SLA Production Throughput, Quality, and Capability

The SLA 750 delivers superior surface quality and accuracy at every point across large builds, with superior detail resolution, wall smoothness, and incremental fidelity.

Production-grade photopolymer materials, advanced software workflow, and optimized laser scanning technology combine to deliver a high throughput, automation-capable solution for production SLA.
