New SLA 750 from 3D Systems goes large for production

761 0

3D Systems has launched a new SLA 750 stereolithography 3D printer line-up, designed to address large format or high volume production applications, with a synchronous, dual-laser option for increased production.

3D Systems says that the solution has been optimised for cost-effective SLA batch part production at ‘up to twice the speed and triple the throughput’ of other available stereolithography solutions.

Additionally, the entire solution has been readied for factory floor integration with its Oqton Manufacturing software, resulting in a solution capable of delivering large, production resin parts and batch part production.

The SLA 750 is a single-laser configuration that delivers reportedly up to 30% faster print speeds and is field-upgradable to the SLA 750 Dual. Both printers feature a 15% larger build envelope and smaller hardware footprint than previous models, allowing manufacturers to optimise and scale production.

The system features a self-calibrating dual-rail recoater to improve print process reliability and final part mechanical properties.

Both laser options utilise 3D Systems Hyper-Scan vector technology – a proprietary scanning algorithm focussed on improving key speed and productivity elements such as laser focus and power, as well as vector motor kinematics to deliver significant printer speed and throughput benefits.

Automation readiness is something designed into the SLA 750 line-up, as both current models are robot compatible for 24/7 lights-out operation.


Both printers include 3D Sprint for build prep from 3D CAD data.

“I see the launch of this new platform – which includes a synchronous dual-laser option, Accura materials, and the specialized curing oven – as an example of how we are executing on a global AM strategy that focuses on our strengths,” said Dr. David Leigh, executive VP and CTO for additive manufacturing, 3D Systems.

“I believe we are entering an era where there will be a path of rapid evolution to our innovations. In this light, our multi-purpose SLA platform will become a system that can help scale production applications through built-in functional and throughput enhancements.”

The SLA 750 line-up are compatible with 3D Systems’ toughest production-grade SLA resin, Accura AMX Durable Natural, is formulated to withstand repeated flexing and bending, as in this mandrel tool which can be removed whole from convoluted carbon fibre tubing.

Additionally, 3D Systems’ PostCure 1050 post-processing system for high-volume, high-speed drying and curing for batch jobs and large parts up to 1050 x 750 x 600mm is also compatible.

General availability of the SLA 750 is planned for the second quarter of 2022, and the SLA 750 Dual is planned to be available in the fourth quarter of 2022.
