Overview
The Concept Laser M1 Cusing is a mid-range laser powder bed fusion (LPBF) system that bridges the gap between the compact Mlab Cusing research platform and the full industrial-scale M2 Cusing production machine. With a build envelope of 250 x 250 x 250 mm and a 200W fiber laser, the M1 Cusing targets job shops, contract manufacturers, and mid-size industrial users who need genuine production capability without the capital expenditure of a large-format dual-laser system. It was one of Concept Laser's most commercially successful machines during the 2010s and helped establish the company's presence in aerospace and medical device manufacturing.
The M1 Cusing features Concept Laser's proprietary 'island scanning' strategy, which divides each layer into small 5 x 5 mm exposure fields ('islands') that are processed in randomized order. This technique reduces residual stress accumulation during the build, improving dimensional accuracy and mechanical property consistency — particularly important for large, flat cross-sections in aluminum and titanium alloys. The approach has been widely recognized in the AM industry as a meaningful contribution to part quality in LPBF.
Material versatility is a key strength of the M1 Cusing. The system supports stainless steels (316L, 17-4PH), tool steels (1.2709 maraging steel), aluminum alloys (AlSi10Mg), titanium (Ti-6Al-4V), cobalt-chrome alloys, and nickel superalloys (Inconel 625). An inert atmosphere option is available for reactive material processing, expanding the machine's capability to medical-grade titanium implants and aerospace-grade nickel components. The powder management system is designed for efficient material change and recovery, reducing waste on expensive specialty powders.
As part of the GE Additive portfolio, the M1 Cusing continues to be supported with materials qualification data and process parameter sets developed by Concept Laser and GE's application engineering teams. It remains a practical choice for organizations that have validated LPBF for their application and are ready to move from prototyping to low-to-medium volume production of near-net-shape metal components, particularly in tooling, implants, and aerospace brackets.

Strengths & Limitations
Strengths
- Proven island scanning strategy reduces residual stress and improves dimensional accuracy for large cross-section parts
- 250 x 250 x 250 mm build volume accommodates a broad range of industrial components across aerospace, medical, and tooling
- Wide material compatibility including reactive alloys (Ti, Al) with inert atmosphere option
- Well-established platform with extensive published materials data and process parameters from Concept Laser and GE Additive
- Mid-range capital cost provides production-grade LPBF capability without the premium of large-format dual-laser systems
Limitations
- Single 200W laser limits throughput compared to higher-power (400W+) or multi-laser competitors in the same build volume class
- Older platform design means some automation and software features lag behind newer-generation LPBF systems from EOS, SLM Solutions, and Trumpf
- Build height of 250 mm restricts options for tall components like turbine blades or long-bone orthopedic implants

Frequently Asked Questions
01
Island scanning is Concept Laser's patented strategy that divides each build layer into small 5 x 5 mm 'islands' processed in a randomized sequence. This distributes heat more evenly across the layer, reducing thermal gradients and residual stress — leading to better dimensional accuracy and more consistent mechanical properties.
02
The M1 Cusing uses a single 200W laser and has the same 250 x 250 mm footprint but a taller 250 mm build height. The M2 Cusing offers higher laser power (up to 400W dual-laser) and a taller 280 mm build height, along with enhanced automation and throughput for higher-volume production.
03
Yes. With the inert atmosphere option maintaining oxygen below 100 ppm, the M1 Cusing can process Ti-6Al-4V ELI (extra-low interstitial) powder to medical device standards, and the platform has been used for FDA-cleared implant production.
04
The M1 Cusing uses Concept Laser's Magics-based build preparation software with proprietary process parameter sets. GE Additive has integrated this into their broader digital workflow tools for fleet management and quality documentation.
05
GE Additive has transitioned its LPBF product line toward newer platforms (Concept Laser M Line and X LINE families). The M1 Cusing is primarily available on the used equipment market, where it remains a cost-effective entry into mid-range industrial LPBF.
