Is the OMTech Pro 3655 Hybrid Worth It? The CO2 Laser That Also Cuts Sheet Metal
Quick answer: The Pro 3655 Hybrid costs $11,999.99 — about $3,800 more than the standard Pro 3655 150W ($8,199.99) — and that premium buys a second, oxygen-assisted laser head that cuts thin stainless, carbon, and galvanized steel up to 1.5mm. It's not a fiber laser bolted onto a CO2 machine; it's the same 150W CO2 source doing the cutting, using oxygen instead of air as the assist gas to trigger a thermal oxidation reaction in the metal. If sheet metal cutting is a real, recurring part of your work, the Hybrid consolidates two machines into one footprint. If it isn't, the standard Pro 3655 does everything else identically for less money.

How the Hybrid Actually Cuts Metal
The Hybrid isn't a more powerful version of the standard Pro 3655 — both run 150W CO2, and neither has a separate fiber laser source. Instead, the Hybrid adds a second laser head configured with oxygen as the assist gas instead of air. According to OMTech's own product documentation, that oxygen feeds a thermal oxidation reaction that lets the CO2 beam cut through thin steel — a completely different mechanism from how a true fiber laser cuts metal, and the reason the Hybrid's metal-cutting depth (1.5mm) is much shallower than a dedicated fiber cutter like the FC-22 (up to 10mm on carbon steel).
On non-metal work — wood, acrylic, leather — the Hybrid performs identically to the standard Pro 3655, so you're not paying for improved CO2 performance, only for the added metal-cutting capability and the oxygen assist infrastructure (tubes included) that makes it work.
Who the Hybrid Is Actually For
"The right customer for the Hybrid, instead of the standard Pro 3655, is a shop that isn't just cutting wood regularly as part of daily production," says Shishir Nigam, Founder of The Maker's Chest. "They also need to cut thin metal sheets as part of their production cycles. Those are the customers who really benefit from the Hybrid's capabilities — it saves a lot of space when a separate metal-cutting CNC router or fiber laser isn't required just for cutting through thin sheets up to 1 or 1.5mm thick."
What It Can't Do
"I'd specifically caution customers who think the Hybrid will replace a true fiber laser metal-cutting machine — that's certainly not the case," Nigam says. "You cannot cut metal thicker than 1.5mm with the Hybrid model. You need a true fiber laser, running 1,000 to 2,000W of fiber power, to cut metal thicker than that."
This is the single most important thing to understand before buying the Hybrid — it solves the occasional thin-stainless problem for a CO2 shop, it doesn't replace dedicated metal-cutting equipment for a business built around fabrication.
When the Premium Pays Off
"The additional premium usually pays off when, for example, a sign-making shop isn't just cutting simple acrylic signs but also overlaying those signs with thin sheets of metal," Nigam says. "The Hybrid capability lets the same machine complete a much more complex job than just cutting pure acrylic."
That's a concrete, specific version of the general case: any shop where metal shows up as an occasional add-on to an otherwise CO2-material workflow — not a standalone metal fabrication business — is the sweet spot for this machine.
Choose Hybrid If / Choose Standard Pro 3655 If
Choose the Pro 3655 Hybrid if:
- You occasionally need to cut thin stainless, carbon, or galvanized steel (up to 1.5mm) alongside standard CO2 work
- Your work is closer to sign-making with occasional metal overlays than daily heavy fabrication
- You want to avoid turning away or outsourcing occasional metal jobs
Choose the standard Pro 3655 if:
- Your work is entirely wood, acrylic, leather, and other CO2 materials
- Metal cutting isn't part of your business, even occasionally
- You'd rather save the $3,800 premium for other equipment
Frequently Asked Questions
Does the Pro 3655 Hybrid have a fiber laser in it?
No — this is a common misconception. Both laser heads run off the same 150W CO2 source. The "metal-processing" head cuts thin steel by using oxygen as the assist gas to trigger a thermal oxidation reaction, not by using fiber laser technology.
How thick a stainless steel part can it cut?
Up to 1.5mm in a single pass when connected to an oxygen supply and using the metal-processing laser head.
Is the Hybrid a replacement for a dedicated fiber laser cutter?
No — per The Maker's Chest's own explicit guidance to customers, it does not replace a true fiber metal-cutting machine and cannot cut beyond 1.5mm. A dedicated fiber cutter like the FC-22 (1,000-2,000W fiber power) is required for thicker material.
Who benefits most from the extra $3,800?
Shops where metal shows up as an occasional, secondary part of the work — like a sign-making business overlaying acrylic signs with thin metal accents — rather than businesses built primarily around metal fabrication.
