Umprotech Enclosed Fiber Laser Cutter – 3 kW · 4×8 ft · FSCUT
A fully enclosed 3 kW fiber laser cutting system engineered for US job shops, OEMs, and fabrication cells that need more speed and thickness capacity than entry-level lasers, without moving up to a large-format or high-kW platform. The 3 kW source in a standard 4×8 ft (48×96") envelope delivers clean, repeatable cuts on steel, stainless, aluminum, and more—backed by industrial FSCUT control and CypCut CAM.
Laser power: 3 kW · Bed size: 4×8 ft (48×96") · Controller: FSCUT with CypCut · Enclosure: Full-cover, Class 1
Key advantages for US buyers
The 3 kW, 4×8 ft Umprotech enclosed fiber laser is designed as a production-ready cutting cell for shops that run thicker gauges, want faster cycle times, or are replacing plasma/shear work with laser precision. It combines standard North American sheet handling with the safety and cleanliness of a fully enclosed Class 1 system.
- 3 kW fiber laser power: adds cutting headroom versus 1–2 kW systems, supporting typical 3 kW ranges in mild steel, stainless, and aluminum for contract fabrication, OEM components, and general job shop work.
- Standard 4×8 ft (48×96") bed: accepts full-size North American sheets for efficient nesting, reduced trim waste, and straightforward material handling with common carts and racks.
- Full-cover, Class 1 enclosure: light-tight housing with safety interlocks and filtered windows, suitable for mixed-use production floors where laser safety and clean air are critical.
- Integrated fume extraction and industrial chiller: included as part of the package to maintain cut quality, protect optics, and support multi-shift operation when installed correctly.
- FSCUT controller with CypCut CAM: widely used industrial control stack with fast DXF import, intelligent nesting, micro-joints, corner smoothing, and simulation for reduced programming time and predictable cycle times.
- Auto-focus cutting head: motorized focus adjustment tracks thickness changes and sheet warp, keeping kerf width, pierce reliability, and edge quality consistent across the entire 4×8 bed.
- Raycus or IPG fiber source options: choose the powertrain that fits your internal standards, service model, and budget without changing the overall machine concept.
- Assist gas flexibility: supports N2, O2, and dry air, allowing you to balance edge quality, speed, and cost per part depending on material and job type.
Key technical specifications
This 3 kW enclosed fiber laser is delivered as a complete cutting system: fiber source, motion platform, controller, enclosure, chiller, and fume extraction are designed to work together as a production cell when installed and maintained according to specification.
Laser power: 3 kW fiber (Raycus or IPG)
Industrial-grade fiber source sized for higher cutting speeds and increased thickness envelope compared to 1–2 kW systems, while still keeping electrical and gas consumption manageable for mid-size shops.
Working area / bed size: 4×8 ft (48×96" / ~1219×2438 mm)
Designed around standard 4×8 sheet stock for structural parts, panels, and OEM flat patterns; supports efficient nesting strategies and straightforward integration with existing material storage.
Controller & CAM: FSCUT with CypCut
Includes DXF/DWG import, automatic and manual nesting, lead-in/lead-out control, micro-joints, common-edge cutting, corner smoothing, and graphical simulation, helping programmers verify toolpaths before cutting.
Cutting head: Auto-focus fiber cutting head
Motorized focus and capacitive height sensing handle varying plate flatness and thickness; focus presets and parameter libraries in CypCut simplify setup for different materials and gauges.
Enclosure: Full-cover, Class 1
Light-tight enclosure with interlocked doors and observation windows; designed to contain reflections, smoke, and noise, and to support safety compliance in general fabrication shops, schools, and OEM plants.
Fume extraction: Integrated extraction system
Pulls fumes at the cutting zone through ducted extraction; proper connection to your facility exhaust helps protect optics, maintain beam quality, and keep the shop environment cleaner and safer.
Cooling: Industrial chiller (included)
Dedicated chiller circuit for the laser source and optics, maintaining stable temperatures for consistent performance and extended component life under continuous or multi-shift production loads.
Assist gases: N2, O2, dry air
Configure nitrogen for oxide-free edges on stainless and aluminum, oxygen for fast production cutting of carbon steel, and shop air for cost-effective cutting on non-cosmetic parts where light oxidation is acceptable.
Motion system: Servo-driven gantry
Precision servo motors and a rigid gantry structure (with linear guides and appropriate drives) provide repeatable positioning, sharp internal corners, and smooth contouring over the entire 4×8 workspace.
Typical cutting range (reference only):
Representative ranges for 3 kW systems (exact capacity depends on material grade, gas, and quality
requirements):
· Carbon steel – thin sheet through mid-gauge plate in O2 or N2
· Stainless steel – enclosure and bracket gauges in N2 with bright edges
· Aluminum – common cover and panel thicknesses using N2 or air
· Non-ferrous (e.g., brass) – signage and hardware thicknesses within rated charts
Note: final cutting capacity and speed are influenced by material grade and surface, gas quality/pressure, nozzle selection, and cut parameters. Always validate critical thicknesses and edge requirements with test cuts and approved part samples.
Capabilities & typical applications
The 3 kW enclosed 4×8 system is often chosen as a primary cutting cell for shops that need to handle both thin sheet and moderate plate thicknesses, with a mix of prototypes, repeat orders, and production contracts. It integrates naturally with press brakes, hardware insertion, welding, and assembly lines.
- Panels & enclosures: flat patterns for electrical cabinets, industrial controls, machine panels, and access doors in steel, stainless, and aluminum.
- Brackets & mounting hardware: gussets, mounting plates, support brackets, and small structural details prepared for bending and welding.
- HVAC & ducting: flat patterns for duct sections, flanges, hanger brackets, plenums, and housings with clean edges and accurate hole patterns.
- Machine guards & safety components: perforated guards, covers, and shields with consistent hole patterns and perimeter accuracy.
- OEM and contract manufacturing: repeated part families with stored programs and parameter sets, simplifying scheduling and cross-shift operation.
- General job-shop work: one-off and prototype parts alongside small production runs, where quick DXF import and nesting are critical to profitability.
- Integration into fab cells: upstream cutting for press brakes, robotic welding cells, and final assembly, with tooling and bend lines placed in CAD/CAM for smooth handoff.
Process notes & best practices for 3 kW cutting
Getting full value from a 3 kW fiber laser means standardizing a few internal cutting rules and parameter sets tailored to your material mix:
- Align gas choice with edge requirements: use nitrogen for bright edges on stainless and aluminum, oxygen for high-speed carbon steel cutting where oxide is acceptable, and dry air for non-cosmetic production parts where cost per part is critical.
- Build parameter libraries by material & thickness: create named sets (e.g. “A36-10ga-O2”, “304-14ga-N2-finish”, “5052-0.125-air”) and lock them into CypCut so operators select recipes rather than guessing at speed and power.
- Optimize pierce routines for thicker gauges: use dedicated pierce settings (time, power, height) to minimize spatter, improve reliability, and protect the nozzle/protective window on heavy cuts.
- Use micro-joints where needed: apply micro-tabs on small parts or internal scrap to prevent tip-up and collisions, then tune tab size and location for easy removal and clean cosmetic edges.
- Maintain optics and table regularly: establish daily checks for nozzle alignment and protective windows, plus weekly/monthly routines for lens inspection, fume extraction filters, and slat condition on the cutting bed.
- Validate new materials with trial cuts: for any new supplier or grade, run short test nests to confirm edge quality and adjust cut speed, power, and gas pressure before committing to full production.
Capacity and quality always depend on the combination of material, tooling, gas, and parameter setup. We recommend keeping “golden sample” parts and approved parameter sets to benchmark performance over time.
