The CO2 Laser That Also Cuts Sheet Metal — One Machine for Two Workflows.
The OMTech Pro 3655 Hybrid is a 150W CO2 laser cutting and engraving machine with a 2-in-1 dual-head system that supports everyday CO2 material cutting and engraving on wood, acrylic, and leather and sheet metal cutting on stainless steel up to 1.5mm.
In a single machine with a 54" × 34" working area, built-in TEYU water chiller, X/Y servo motors, and four-way pass-through. For fabrication shops, sign shops, and production businesses that currently require two separate machines to cover both material categories, the Pro 3655 Hybrid consolidates that into one production-capable platform.

The Problem This Machine Solves
Most CO2 laser shops run into the same wall eventually: a client wants a stainless steel product — a nameplate, a bracket, a small part — and the shop either has to turn the job away, outsource to a metal shop, or invest in a separate fiber or plasma cutting system.
The Pro 3655 Hybrid was built specifically for this situation. It combines CO2 material cutting, sheet metal cutting, and precision engraving in one production-ready machine, helping users move between everyday CO2 materials and sheet metal projects with less equipment switching.
The hybrid dual-head system includes one nozzle configured for non-metal workflows (wood, acrylic, leather, engraving) and one nozzle configured for metal-cutting workflows (stainless steel, carbon steel, galvanized steel with oxygen). Switching workflows is a nozzle change and a gas change — not a machine change.
For sign shops adding metal fabrication services, custom product businesses expanding into metal goods, and makerspaces equipping a facility for both material categories — the Hybrid eliminates the either/or decision that characterizes every other CO2 laser on the market.
What It Cuts — The Full Dual-Material Scope
Non-metal cutting (standard CO2 head): Acrylic, wood, MDF, plywood, fabric, leather, rubber, cardboard, paper, foam, and plastics — the full range of CO2-compatible cutting and engraving materials at the 150W power level. For the non-metal workflow, the Pro 3655 Hybrid performs identically to the standard Pro 3655 150W CO2 machine.
Sheet metal cutting (metal-processing head + oxygen): Stainless steel, carbon steel, and galvanized steel — up to 1.5mm stainless steel in a single pass when connected to oxygen and using the metal-processing laser head. This capability is the defining differentiator of the Hybrid from every other OMTech CO2 machine.
Important material note: Highly reflective aluminum is not recommended for cutting on this machine — the FAQ specifically notes this. For shops that need to cut bare aluminum, a fiber laser is the appropriate technology.
Engraving (non-metal head): Acrylic, fabric, wood, MDF, leather, cardboard, rubber, Corian, paper, foam, plastics, glass, stone, and anodized aluminum — the full CO2 engraving material range.
The Dual-Head System — How It Actually Works
The 2-in-1 dual-head system is the technical architecture that makes the hybrid capability practical:
Non-metal laser head: Configured for CO2 material cutting and engraving — standard air assist for smoke clearance and lens protection. This is the head used for wood, acrylic, leather, and all everyday non-metal work.
Metal-processing laser head: Configured for sheet metal cutting — requires connection to an oxygen supply (oxygen tubes are included). The oxygen acts as the assist gas that enables the thermal oxidation reaction required for cutting steel at CO2 wavelengths. This is the head used for stainless steel, carbon steel, and galvanized steel work.
Switching between workflows means physically swapping the laser head, changing the assist gas from air to oxygen (or vice versa), and selecting the correct material settings. The machine accommodates both workflows on the same optical path and motion system — no separate machine, no separate workbed, no separate operating software.
Both laser heads include air assist. The ZnSe 63.5mm focus lens and three US-made silicone mirrors are shared across both workflows — high-transmittance, high-reflectivity optics designed for consistent beam delivery across the machine's power range.
54" × 34" Bed + Four-Way Pass-Through — Large-Format Capacity for Both Material Types
The 54" × 34" (1380 × 850mm) working area is one of the largest beds in the OMTech professional lineup — and the four-way pass-through extends that capacity in all four directions:
Front and back pass-throughs (54.3" × 1.6"): Full bed-width openings for material longer than 54" — continuous strip work, long lumber, and extended panels process sequentially without removing the material.
Left and right pass-throughs (37.4" × 1.6"): Lateral pass-throughs for material wider than 34" — the four-way configuration accommodates virtually any flat sheet dimension.
For a fabrication shop processing full-size stainless steel sheets, a sign business cutting oversized acrylic displays, or any production operation where material size regularly exceeds standard bed dimensions — four-way pass-through capability in all directions means no flat material has a hard size limit on this machine.
At 150W on a 54" × 34" field, the quality of the motion system is what determines whether the machine's power translates into consistent, accurate production output or high-spec paperwork.
X/Y-axis servo motors provide closed-loop position feedback — continuously correcting position deviation during high-speed operation. On a bed this large at 1200 mm/s, servo feedback is what maintains mark quality consistency from edge to edge across the full working area.
HIWIN guide rails — a premium linear motion guide brand widely used in precision manufacturing — provide stable, accurate movement and even load distribution at high speed. The combination of servo motors and HIWIN rails is a production-grade motion specification rather than a hobby-grade alternative.
Autofocus adjusts for different material thicknesses automatically — important when switching between thin sheet metal (under 1.5mm) and thick non-metal materials (up to full 150W non-metal cutting depths) in the same production day.
Red dot guidance provides visible origin positioning before the job fires — confirming placement on large panels and metal sheets without test burns.
Built-In TEYU Chiller + Production Safety — Ready to Run
Built-in TEYU RMCW-5200 water chiller: Factory-integrated — no separate chiller purchase, no external unit footprint, no independent maintenance schedule. Total installation cost is known upfront, and the machine occupies a single footprint.

Frequently Asked Questions About OMTech Pro 3655 Hybrid 150W CO2 Laser Cutter and Engraver
Q: How does the hybrid dual-head system actually work? A: The machine ships with two laser heads — one configured for non-metal CO2 cutting and engraving (with air assist), and one configured for sheet metal cutting (with oxygen assist). Both heads mount on the same optical path and use the same motion system. Switching workflows means physically swapping the laser head and changing the assist gas from compressed air to oxygen. The oxygen is connected via the included oxygen tubes — you supply the oxygen source. Both heads include air assist nozzles.
Q: What sheet metal can it cut, and what are the limits? A: Stainless steel, carbon steel, and galvanized steel — up to 1.5mm stainless steel in a single pass when connected to oxygen and using the metal-processing laser head. Highly reflective aluminum is not recommended — the FAQ specifically notes this. This machine does not replace a fiber laser for aluminum cutting or for metals thicker than 1.5mm stainless. For shops whose metal cutting needs are primarily stainless steel parts under 1.5mm, the Hybrid covers that scope directly.
Q: Is oxygen included, or do I need to source it separately? A: Oxygen tubes are included in the package. You supply the oxygen source — a standard industrial oxygen cylinder from a welding supply vendor is appropriate. Contact our team for guidance on oxygen supply requirements before ordering.
Q: Is it compatible with LightBurn? A: Yes — LightBurn is compatible (confirmed in the FAQ). A separate license is required from Lightburn. LaserCAD is included on USB drive. LightBurn runs on Windows, macOS, and Linux.
Q: What is the water chiller situation? A: The TEYU RMCW-5200 is factory-integrated — no separate chiller purchase, no external unit, no additional installation. One machine footprint, one startup sequence.
Q: What are the shipping and installation requirements? A: The Pro 3655 Hybrid ships via freight. Machine dimensions are 82.5" × 64.7" × 42.3". Confirm floor load capacity, installation space, pass-through clearance, oxygen supply access, and exhaust ducting before delivery. Contact our team for pre-delivery planning guidance.
Q: How is this different from the standard Pro 3655 150W CO2? A: The standard Pro 3655 150W is optimized for CO2 material cutting and engraving — wood, acrylic, leather, and similar materials. It cannot cut sheet metal. The Pro 3655 Hybrid adds the dual-head system with a metal-processing laser head and oxygen assist gas compatibility — enabling stainless steel, carbon steel, and galvanized steel cutting up to 1.5mm alongside full CO2 non-metal capability. If sheet metal cutting is any part of your required workflow, the Hybrid is the appropriate machine.
Q: Why buy from The Maker's Chest instead of directly from OMTech? A: Our 75-day return window gives you real dual-workflow evaluation time — enough to run both the metal cutting and CO2 material cutting workflows through your actual production requirements, confirm the Hybrid performs for both use cases, and make an informed decision before you're locked in. Our USA-based expert support team is reachable by phone and email for LightBurn and LaserCAD setup, dual-head workflow configuration, oxygen supply guidance, and production troubleshooting throughout your ownership.
