Boss Laser Applications

Only with the right configuration. A standard CO2 laser is built for non-metal materials — wood, acrylic, leather, paper, and fabric. To cut metal you generally want a fiber source. Two Boss platforms bridge CO2 and metal:

CO2 + thin metal

HP Series

Adds a 150-watt CO2 source plus the ability to cut thin sheet metal up to roughly 18 ga stainless with the right setup.

CO2 + fiber

FlexCut

Pairs a 1.5 kW fiber source with a CO2 tube in one machine, so you can cut metal and non-metal on the same bed.

It depends on the power level and the metal. Pierce thickness is not production thickness — a machine that can pierce a given plate will run faster and cleaner well below that limit. Match wattage to the thickest material you cut regularly, not the thickest you cut once.

Oxygen is fast and economical on mild steel but leaves an oxide edge. Nitrogen produces clean, oxide-free edges on stainless and aluminum at higher cost. Compressed air is a budget option for thin material. Match the gas to the metal and the edge you need.

Cut with nitrogen at sufficient pressure to blow molten metal clear before it oxidizes. Keep the nozzle, focus, and standoff dialed in, and step up gas pressure as thickness increases. Oxygen will cut stainless but discolors the edge.

No. More power raises top-end thickness and speed, but it also raises machine cost, gas use, and operating expense. The right machine matches your real material mix and volume — over-buying wattage you never use is a common mistake.

Marking changes the surface color or oxide without removing material (annealing). Etching melts a shallow, high-contrast layer. Engraving removes material for a mark you can feel. Choose by how much depth, contrast, and durability the part needs.

Yes — that’s annealing. The beam heats the surface to grow a controlled oxide layer, producing a black or colored mark flush with the surface. It’s the preferred method for medical, food, and corrosion-sensitive parts.

On anodized aluminum a fiber laser bleaches the dye layer to a bright white mark with very little power and high speed. It’s fast, high-contrast, and needs no consumables — one of the easiest marking jobs there is.

A smaller field lens concentrates the beam for the finest detail; a larger field lens covers bigger parts in one pass but with a larger spot. Match lens and field size to your part dimensions and the smallest feature you need to resolve.

An annealed or deep-engraved mark resists abrasion and corrosion far better than a surface etch. For parts exposed to wear, cleaning, or weather, choose annealing or engraving and validate the mark against your read and durability requirements.

Cut cast acrylic at a speed and power that melts the edge cleanly in a single pass, with minimal air disturbance at the cut line. Too much air or too many passes frosts the edge — the clearest results come from cast stock and a tuned single-pass cut.

Cast acrylic engraves with a bright frosted contrast and gives the clearest cut edges; extruded acrylic cuts with very clean edges and melts more uniformly but engraves with less contrast. Choose cast for engraving, either for cutting.

Cast acrylic frosts white when engraved — that’s the desired high-contrast look. Extruded acrylic engraves shallow and dull by comparison. If your engrave looks weak, confirm you’re running cast stock.

Leave masking on for engraving’s neighboring areas and remove or score it where you cut, depending on the job. Masking protects the surface from smoke residue; test whether your artwork reads better masked or unmasked before the full run.

Never cut PVC or vinyl — they release chlorine gas that’s hazardous to you and corrosive to the machine. Polycarbonate cuts poorly and discolors. Stick to acrylic, Delrin, and laser-rated engraving plastics, and verify any unknown material first.

Char comes from too much heat lingering on the cut line. Increase air assist, raise speed, lower power to the minimum that still cuts through, and mask the surface. Resinous woods and dense plywood char more — expect to tune per species.

Convert the image to greyscale, adjust contrast so detail survives the engrave, and apply a dithering pattern suited to wood. Test on scrap to set the depth and resolution before committing to the final piece.

Even-grained, low-resin woods and quality plywood cut cleanest. Knots, heavy grain, and glue-rich engineered boards burn unevenly. For consistent results pick laser-grade plywood and keep the bed level.

Depth is driven by power and the number of passes; contrast by speed and resolution. Slower passes burn darker and deeper. Build a small test grid of power-and-speed combinations for each wood you run regularly.

Yes, with a rotary attachment that turns the workpiece under the beam. Set the diameter correctly so the artwork wraps without distortion, and keep focus consistent across the curve.
