**Short answer:** A gun shop laser engraving station needs four things: a dedicated, sturdy bench away from customer traffic, a controlled work area for a Class 4 laser with 1064 nm-rated eye protection, a fume extractor that filters both particulate and gases, and a written workflow that ties every engraving job to your FFL records. Most shops fit a desktop fiber laser, a fume extractor, a parts cart, and a fixture shelf into a corner of the gunsmithing area. The workflow matters as much as the hardware: in our shop, an Edge 30W reaches ATF .003" depth on a 1/16"-tall serial number in steel in 20 passes, about 2 minutes, so the machine is rarely the bottleneck. Intake, logging, setup, and quality checks are.

## Pick the Right Spot in Your Shop

Put the laser where you already handle customer firearms: behind the counter in the gunsmithing or back-room area, not on the sales floor. That keeps guns that are checked in for work separated from inventory, limits who can walk into the laser's work area, and keeps fumes and noise away from customers.

Look for a spot with:

- **A solid, level bench.** Vibration and a wobbly table show up as soft or doubled edges. A heavy steel or thick wood bench that isn't shared with a bench grinder or vise is ideal.
- **Room on both sides.** You need space to load long parts like barrels, uppers, and suppressor tubes, plus room for a rotary attachment.
- **An outside wall if possible.** It makes ducting a fume extractor to the outdoors easier if you choose that route.
- **A dedicated outlet.** Follow the electrical requirements in your machine's and extractor's manuals, and don't share the circuit with compressors or other large motors.
- **A clean, dry environment.** Dust, grit from blasting cabinets, and overspray from Cerakote booths don't belong near the lens. If you coat in-house, keep the laser out of the spray area.

## Laser Safety for a Class 4 Fiber Laser

Edge Series fiber lasers are Class 4 lasers. The beam is invisible (fiber lasers operate in the near infrared, around 1064 nm), and direct or reflected exposure can injure eyes and skin. Shiny steel, stainless, and polished brass reflect, so treat reflections as seriously as the direct beam.

- **Eye protection rated for the wavelength.** Use laser safety glasses marked for 1064 nm with an optical density appropriate for your laser. Ordinary safety glasses and shaded welding lenses are not laser protection.
- **Control the area.** Mark the station with laser warning signage, keep customers and untrained staff out while it runs, and use enclosures or barriers to block stray reflections.
- **Follow the recognized standard.** ANSI Z136.1 is the standard U.S. employers use for laser safety programs. For a Class 4 laser, that typically means a designated person responsible for laser safety, written procedures, and training for anyone who runs the machine.
- **Fire readiness.** Keep a fire extinguisher at the station, never leave a running job unattended, and keep rags, cardboard, and solvents away from the work area.

## Ventilation and Fume Extraction

Engraving vaporizes material. On gun parts that means metal particulate from steel and aluminum, plus smoke and gases from anodizing, Cerakote, paint, and polymer frames and magazines. That's not something to breathe in a closed back room, and residue also builds up on the lens and inside the shop.

- **Capture at the source.** Place the extractor's intake nozzle close to the engraving spot so fumes are pulled away before they spread.
- **Filter both particulate and gases.** Most shop extractors use staged filtration: a pre-filter, a HEPA filter for fine particles, and activated carbon for odors and gases. Polymer and coating work is where the carbon stage earns its keep.
- **Replace filters on schedule.** A saturated filter quietly stops working. Track run hours and follow the manufacturer's replacement intervals.
- **Venting outdoors is an option** when the building allows it, but check local codes and your landlord's rules first.

If you engrave a lot of polymer, see our post on [engraving PMags, Glock frames, and grips](https://go.salasers.com/blog/can-a-fiber-laser-engrave-polymer-pmags-glock-frames-and-grips), and for coated parts our [Cerakote workflow guide](https://go.salasers.com/blog/engrave-before-or-after-cerakote-a-laser-workflow-guide-for-coating-shops).

## Fixtures, Tools, and Supplies to Keep at the Station

A tidy station is a fast station. Keep these within arm's reach:

- **Lenses.** Every Edge ships with multiple lenses (112mm, 220mm, and 300mm field profiles). Store the ones you aren't using in a closed case so they stay clean.
- **Fixtures and jigs.** A repeatable fixture for AR-15 lowers, slides, and common frames saves minutes on every job. Our [AR-15 lower setup guide](https://go.salasers.com/blog/how-to-laser-engrave-an-ar-15-lower-setup-fixtures-and-settings) covers fixturing in detail.
- **A rotary attachment** for barrels, suppressor tubes, and round parts.
- **Measuring tools.** A depth gauge or indicator to confirm ATF depth, and calipers to check letter height.
- **Cleaning supplies.** Degreaser and lint-free wipes for parts, and lens cleaning supplies.
- **Scrap test pieces** of steel, stainless, anodized aluminum, and polymer for test spots before you touch a customer's part.

Every Edge also ships with a full supply kit to get the station running.

## Build a Settings Library Before Your First Customer Job

Guessing at settings is a common source of rework. Every Edge ships with LightBurn and a LightBurn settings bundle of presets, so you start from tested numbers instead of guessing. Name your layers clearly, lock in the presets you use daily, and record any adjustments you make for specific parts. Here are a few presets that cover common gun-shop jobs:

| Job | Power | Speed | Frequency | Line interval |
| --- | --- | --- | --- | --- |
| Anodized aluminum mark (flat and rotary) | 60% | 3,048 mm/s (120 in/s) | 25 kHz | 0.051 mm |
| Deep engrave "Cut" layer on metal | 60% | 356 mm/s (14 in/s) | — | 0.051 mm |
| Metal "Clean Up" layer | 55% | 3,048 mm/s (120 in/s) | 45 kHz | 0.051 mm |
| NFA minimum letter height | 100% | 127 mm/s (5 in/s) | — | 0.051 mm |
| Black mark on stainless steel | 30% | 102 mm/s (4 in/s) | 60 kHz | 0.025 mm |

*Edge 50W, 220mm lens. Starting points; confirm on a test spot.*

Each preset is one pass. For depth work like serial numbers, you set the number of repeats per job, and the hatch angle rotates 23.7 degrees per pass on repeated passes to help even out the engraved surface. A different lens or part will need adjustment. For how depth and wattage relate, see [how deep a fiber laser can engrave](https://go.salasers.com/blog/how-deep-can-a-fiber-laser-engrave-atf-.003-depth-tested-on-30w-50w-100w) and [30W vs 50W vs 100W](https://go.salasers.com/blog/30w-vs-50w-vs-100w-fiber-laser-which-wattage-does-a-gun-shop-actually-need).

## Set Up a Workflow That Ties Into Your FFL Records

The laser part of the job is short. The steps around it are where shops lose time or create compliance gaps. A simple station workflow:

1. **Intake.** Write up the job with the customer: what's being engraved, where, font, and size. Get approval on a printed or on-screen proof.
2. **Log it if it stays.** Under ATF rulings, a customer's firearm left for gunsmithing work generally must be entered in your acquisition and disposition (A&D) records unless it is returned the same business day. Many shops log every gun that comes in for work, regardless.
3. **Secure storage.** Keep checked-in guns tagged and stored with your other firearms, not left on the laser bench overnight.
4. **Prep.** Clean and degrease the part, fixture it, and set focus.
5. **Test spot.** Run the preset on scrap of the same material, then on the part.
6. **Engrave and verify.** For required markings, confirm depth (minimum .003", measured from the flat surface of the metal) and serial number height (minimum 1/16") under 27 CFR 478.92.
7. **Clean, photograph, and return.** Photograph the finished marking for your job file, then complete the disposition entry when the gun goes back to the customer.

Our [ATF compliance guide](https://go.salasers.com/blog/fiber-laser-engraving-for-firearms-atf-compliance-guide) covers marking requirements in more depth.

*This is general information, not legal advice. Confirm your recordkeeping and marking obligations with ATF or a firearms compliance professional.*

## Train the People Who Run It

A well-built station only pays off if more than one person can run it safely and consistently. Write down your safety rules, your settings library, and your workflow, and make sure each operator has run test pieces on every material you engrave before handling customer parts. SA Laser's [Spark training](https://salasers.com/spark/) is a 5-day, in-person, hands-on training course for operators.

## Frequently Asked Questions

### How much space do I need for a laser engraving station?

Most gun shops fit a desktop fiber laser, a fume extractor, and a small parts cart onto one sturdy bench with clearance on both sides for long parts and a rotary. Plan the space around the longest part you'll engrave, like a barrel or suppressor tube.

### Do I need a fume extractor for a fiber laser?

Yes. Engraving steel, aluminum, coatings, and polymer produces fine particulate and gases. A multi-stage extractor with HEPA and activated carbon filtration, with the intake close to the work, is the common shop setup.

### What safety glasses do I need for a fiber laser?

Laser safety glasses rated for the 1064 nm wavelength with an appropriate optical density for your machine. Regular safety glasses and welding shades do not protect against a fiber laser beam.

### Do I have to log a customer's gun in my A&D book if I'm just engraving it?

Generally, yes, if the gun stays past the same business day. The same-business-day rule applies to firearms left for repair or gunsmithing work, which is how most shops treat engraving jobs. Confirm the details for your license type with ATF.

### How long does an ATF serial number engraving take?

In our shop, an Edge 30W reaches ATF .003" depth on a 1/16"-tall serial number in steel in 20 passes, about 2 minutes. Higher wattage is generally faster, but intake, fixturing, and verification usually take longer than the engraving itself.

### What settings should I start with?

Start from tested presets rather than guessing. Every Edge ships with a LightBurn settings bundle; for example, our Edge 50W anodized aluminum preset is 60% power at 3,048 mm/s (120 in/s), 25 kHz, on the 220mm lens. Always confirm on a test spot first.
