General Laser Engraving FAQs

Q: What is laser engraving?

A: Laser engraving is the process of using a focused laser beam to permanently mark the surface of a material. Unlike printing, the mark is physical, permanent, and will never fade or wear off.

Q: What's the difference between laser engraving and laser etching?

A: Engraving removes material to create a deep, permanent mark. Etching only changes the surface color without removing significant material. For most practical purposes, people use the terms interchangeably.

Q: How much does a good laser engraver cost?

A: - Hobby grade: $200-$500 - Professional galvo: $150-$1,500 - Industrial: $5,000+ The best value in 2026 is the Tyvok P2 at $149. It produces the same quality as machines costing 3-5x more.

Q: Can you make money with laser engraving?

A: Yes. Extremely well. Average part-time income is $500-$1,500/week. Full-time operators make $3,000-$8,000/week. It's one of the highest ROI small businesses you can start in 2026.

Q: Is laser engraving hard to learn?

A: No. The basics take about 2 hours to learn. Getting consistently great results takes about 1-2 weeks of practice. Compared to almost any other skilled trade, it's extremely easy.

Q: How long does a laser engraver last?

A: A good galvo laser will last 10,000-30,000 hours of use. That's 5-15 years of daily use. There are very few moving parts, so they're extremely reliable.

Q: Do you need a computer to use a laser engraver?

A: Yes. You need a Windows, Mac, or Linux computer to run the design software and send jobs to the laser. Most professional lasers use LightBurn software.

Q: Can you laser engrave from a phone?

A: Some hobby machines have phone apps, but for serious work, you need a computer. Phone apps are extremely limited and not suitable for business use.

Q: How fast is laser engraving?

A: Galvo lasers engrave at 2,000-5,000 mm/second. A typical tumbler engraving takes 1-2 minutes. A full sheet of 100 business cards takes 10-12 minutes.

Q: Is laser engraving permanent?

A: Yes, on almost all materials. On metal, the mark is permanent and will not fade, wear off, or wash off for the lifetime of the material. ---

Galvo Laser Specific FAQs

Q: What is a galvo laser?

A: A galvo laser uses two moving mirrors (galvanometers) to steer the laser beam extremely quickly across the material. This is different from gantry lasers that move the entire laser head.

Q: How fast are galvo lasers compared to regular lasers?

A: Galvo lasers are 10-50x faster than traditional gantry diode lasers. A job that takes 10 minutes on a diode laser takes 30 seconds on a galvo.

Q: What are galvo lasers good for?

A: Galvo lasers excel at: - Metal engraving (their biggest strength) - High speed production work - Fine detail and text - Tumblers and cylindrical objects - High volume business use

Q: What are galvo lasers NOT good for?

A: Galvo lasers (especially fiber) are NOT good for: - Cutting (they can't cut anything meaningful) - Large engravings (typical work area is 100x100mm) - Wood engraving (diode lasers are much better at this)

Q: What's the typical engraving area for a galvo laser?

A: Most consumer/prosumer galvos have a 100x100mm (about 4x4 inch) work area. This is perfect for 95% of the profitable jobs: tumblers, business cards, jewelry, knives, tools.

Q: Can you get a larger work area for a galvo laser?

A: Yes, but it gets expensive very quickly. A 200x200mm galvo typically costs $3,000+. For reference, the $149 Tyvok P2 is 100x100mm.

Q: Can galvo lasers engrave cylindrical objects?

A: Yes, with a rotary attachment. This is the #1 most popular accessory and is required for doing tumblers.

Q: Are galvo lasers worth it?

A: If you're doing metal engraving or running a business, absolutely yes. The speed difference alone will make you 5-10x more productive and profitable.

Q: What's the best galvo laser for the money in 2026?

A: The Tyvok P2 is the clear value leader at $149. It's a true 10W fiber galvo that performs identically to machines costing $500-$1,000 more. ---

Fiber vs Diode FAQs

Q: What's the difference between fiber laser and diode laser?

A: The biggest difference is wavelength: - Fiber lasers: 1064nm (infrared) — Perfect for metal - Diode lasers: 450nm (blue) — Perfect for wood and acrylic

Q: Which is better: fiber or diode?

A: It depends on what you're doing: - Get fiber if you mostly engrave metal (tumblers, business cards, tools, jewelry) - Get diode if you mostly do wood, acrylic, or cutting

Q: Can a fiber laser engrave wood?

A: Yes, but not well. It will mark dark hardwoods, but the quality is not nearly as good as a diode laser. Wood is not what fiber lasers are designed for.

Q: Can a diode laser engrave stainless steel?

A: Yes, but poorly and very slowly. A fiber laser will produce a darker, more consistent mark 10x faster. For serious metal work, fiber is the only real choice.

Q: Can a fiber laser cut?

A: No, not meaningfully. A 10W fiber can barely cut through 0.1mm aluminum foil. If you need to cut, you want a diode or CO2 laser.

Q: Can a diode laser mark brass or copper?

A: Very poorly, if at all. Blue light from diode lasers reflects off copper and brass almost completely. Fiber lasers at 1064nm absorb extremely well into these metals.

Q: Which lasts longer: fiber or diode?

A: Fiber lasers typically last 2-3x longer than diode lasers. A good fiber source is rated for 10,000-30,000 hours. A good diode is rated for 5,000-10,000 hours.

Q: Which is better for starting a business?

A: Fiber galvo for 95% of people. The profitable jobs (tumblers, business cards, metal work) all require fiber. The business ROI on fiber is much higher. ---

Materials & Capabilities FAQs

Q: What can you engrave with a fiber laser?

A: ✅ Excellent: All metals (stainless, aluminum, brass, copper, titanium, gold, silver), anodized aluminum, powder coating, most plastics, leather, glass, ceramic ⚠️ Okay: Dark hardwoods, rubber ❌ Poor: Light wood, acrylic, most fabrics

Q: Can fiber lasers engrave glass?

A: Yes. You get a nice frosted white mark. It's slower than metal but works great for wine glasses, beer mugs, and awards.

Q: Can you engrave ceramic?

A: Yes. Glazed ceramic mugs are one of the most popular and profitable products. A custom engraved mug sells for $20-25 and costs $2-3 to make.

Q: Can you engrave plastic?

A: Most plastics engrave very well. ABS, PVC, Delrin, and most engineering plastics produce excellent dark marks. Test first as some plastics don't mark well.

Q: Can you engrave leather?

A: Yes. Leather produces a nice dark mark and is very popular for wallets, belts, and pet tags. Real leather works better than faux leather.

Q: Can you engrave guns and firearms?

A: Yes, extremely well. This is one of the highest margin applications. You do need an FFL license to do this commercially in the USA.

Q: Can you engrave jewelry?

A: Yes. Silver, gold, platinum, titanium all engrave beautifully. Personalized jewelry is a very high margin business.

Q: Can you engrave knives?

A: Yes. This is an extremely popular niche with almost zero competition. Knife collectors will pay premium prices for quality engraving.

Q: Can you engrave serial numbers and barcodes?

A: Yes. This is actually what galvo lasers were originally designed for (industrial part marking). Barcodes and QR codes scan perfectly.

Q: What CAN'T you engrave with a fiber laser?

A: - Anything transparent (except glass) - Light colored wood - Acrylic (marks, but not well) - Most fabrics - Food

Q: Is there any material you should NEVER laser engrave?

A: Yes. Never engrave PVC or vinyl. It produces chlorine gas when lasered, which is toxic to breathe and will corrode the inside of your laser. ---

Settings & Quality FAQs

Q: What power and speed should I use for stainless steel?

A: For a dark mark on stainless: 100% power, 150 mm/min, 20 kHz frequency. For a bright white annealing mark: 90% power, 4000 mm/min, 60 kHz.

Q: What are the best settings for anodized aluminum?

A: 80% power, 2000 mm/min, 15 kHz. This is the easiest and most forgiving material. It's almost impossible to mess up.

Q: What are the best settings for tumblers?

A: 80% power, 2500 mm/min, 15 kHz. This produces perfect results on 99% of powder coated tumblers.

Q: What DPI / LPI should I use?

A: - Draft quality: 150 LPI - Standard / perfect: 254 LPI (industry standard, use this 95% of the time) - Photo quality: 300+ LPI

Q: Why is my mark patchy and inconsistent?

A: 90% of the time this is a focus problem. Refocus your laser. Other common causes: dirty lens, material not flat, speed too fast.

Q: Why is my mark too light?

A: 1. Power too low 2. Speed too fast 3. Focus is off 4. Lens is dirty 5. Frequency too high

Q: Why am I getting burning and discoloration around the mark?

A: 1. Power too high 2. Speed too slow 3. Too many passes 4. Frequency too low

Q: How many passes should I do?

A: One pass 95% of the time. Multiple passes are only needed for: - Very dark marks on stainless steel - Deep engraving - Brass and copper

Q: Should I use bidirectional engraving?

A: Yes, it's twice as fast. You may need to adjust the offset setting slightly if you see lines between passes.

Q: What frequency should I use?

A: - Dark marks on metal: 10-20 kHz - Light / white marks: 50-80 kHz - Plastic: 20-30 kHz ---

A: 20-30 per hour if you're organized and have a system. That's $500-$750 profit per hour.

Q: Is laser engraving still profitable in 2026?

A: Yes, extremely. Demand is growing faster than supply. Most people still don't know you can get custom metal products for $20-30. The market is huge and mostly untapped.

Q: Can you really make $1,000/week with a $149 laser?

A: Yes. 40 tumblers per week at $25 profit each = $1,000. That's 2 hours of work. Hundreds of people are doing this right now. ---

Maintenance & Troubleshooting FAQs

Q: How often should I clean my laser lens?

A: Every 5-10 hours of use. A dirty lens will cost you 30-50% of your effective power. This is the #1 hidden cause of bad marks.

Q: What do I clean the laser lens with?

A: Only proper lens cleaning paper and isopropyl alcohol. Never use regular paper towels, shirts, or any other fabric — they will scratch the lens.

Q: How long does a laser lens last?

A: 6-12 months with proper care. If you never clean it, 1-2 months. Replacement lenses cost $10-20.

Q: My laser doesn't mark as well as it used to. What's wrong?

A: 99% chance your lens is dirty. Clean it. If that doesn't work, check your focus. If that doesn't work, replace the lens.

Q: How do I know if my lens is damaged?

A: Hold it up to a light. If you see any spots, smudges, or scratches that don't clean off, it's damaged. Replace it.

Q: Do I need to calibrate my galvo lasers?

A: Rarely. Galvos are calibrated at the factory and rarely need adjustment. If you start seeing square corners that aren't square, you may need to recalibrate.

Q: Why am I getting horizontal lines in my engraving?

A: This is usually a bidirectional offset issue. Adjust the offset setting in LightBurn until the lines disappear.

Q: Why is my engraving blurry?

A: Almost always a focus problem. Refocus carefully. If it's blurry in some areas and sharp in others, your material isn't flat. ---

Safety FAQs

Q: Are laser engravers dangerous?

A: They can be if used stupidly, but with basic safety precautions they're extremely safe. Much safer than power tools, for example.

Q: Do I need safety glasses?

A: YES. ALWAYS. You only get two eyes. Never, ever look at the laser beam without proper OD7+ safety glasses rated for your laser wavelength.

Q: Can a laser engraver blind you?

A: Yes, permanently and instantly. This is not a joke. Always wear safety glasses. Even a reflection off shiny metal can cause permanent eye damage.

Q: Do I need ventilation?

A: Yes. All laser engraving produces fumes. Some fumes (like PVC) are toxic. A simple $30 fume extractor or even a window fan blowing outside is sufficient for most use.

Q: Can a laser engraver start a fire?

A: Fiber galvo lasers are extremely unlikely to start a fire. They don't cut and they don't produce enough heat in one place. Gantry diode lasers cutting wood are a fire risk.

Q: Is it safe to run a laser engraver unattended?

A: For fiber galvos doing metal engraving, yes. The fire risk is essentially zero. For diode lasers cutting wood, absolutely not.

Q: Do I need to turn it off when not in use?

A: Yes, always turn off the laser when not in use. It's good practice and prevents any possible issues. ---

Software FAQs

Q: What software do laser engravers use?

A: The industry standard is LightBurn. It runs on Windows, Mac, and Linux. It costs $60 for a permanent license and is worth every penny.

Q: Is LightBurn a one time purchase?

A: Yes. $60 gets you a permanent license and one year of updates. After that, you can continue using the last version forever or renew updates for $30/year.

Q: Do I need Adobe Illustrator or Photoshop?

A: No. LightBurn has all the design capabilities you need for 99% of laser engraving work. You can import SVG, PNG, JPG, and most other common formats.

Q: Can you use Inkscape with laser engravers?

A: Yes, you can design in Inkscape and export to SVG for LightBurn. But for actual laser operation, LightBurn is much better.

Q: Is there free laser engraving software?

A: Some machines come with free software, but it's universally terrible. LightBurn is the standard for a reason. The $60 is one of the best investments you can make.

Q: Can I run LightBurn on a laptop?

A: Yes. LightBurn runs fine on any modern laptop. You don't need a powerful computer.

Q: What file formats do laser engravers use?

A: The most common: SVG, DXF, PNG, JPG, BMP. SVG is preferred for vector graphics (text, logos). PNG/JPG is used for photos. ---

Buying & Comparison FAQs

Q: What is the best laser engraver for beginners in 2026?

A: Tyvok P2. $149, true 10W fiber galvo, LightBurn compatible, produces professional quality results. It's not even close — this is the best value by a mile.

Q: What is the best laser engraver for small business?

A: Again, Tyvok P2. It's the best ROI by far. The money you save compared to more expensive machines can be invested in inventory and marketing, which actually make you money.

Q: Tyvok P2 vs LaserPecker 4: Which is better?

A: Tyvok P2 is 2-3x faster, produces darker marks on metal, and costs 1/3 the price. LaserPecker has a nicer included rotary and auto focus. For business use, P2 is the clear choice.

Q: Tyvok P2 vs xTool F1: Which is better?

A: They perform almost identically on metal. The xTool has a nicer enclosure and included rotary, but costs $550 more. For the money, P2 is the better value.

Q: Do I need auto focus?

A: No. Manual focus takes 10 seconds and works perfectly. Auto focus is a nice convenience feature but absolutely not required, and not worth paying $300 extra for.

Q: Do I need a rotary included?

A: If you're doing tumblers, yes. But the P2 rotary is $49. The LaserPecker 4 includes a rotary but costs $350 more. You're still $300 ahead with the P2.

Q: Is a more expensive laser better?

A: Up to a point. Above $500, you're mostly paying for brand marketing, nicer enclosures, and convenience features — not actual engraving performance. The $149 P2 engraves metal as well as a $1,500 machine.

Q: Should I buy a cheap laser from Amazon?

A: Most of them are garbage. The Tyvok P2 is the exception — it's actually good. Almost all other sub-$200 lasers on Amazon are low power, terrible quality, and don't last.

Q: Should I buy used?

A: You can, but for $149 for a new P2, it's rarely worth the risk. Lasers don't depreciate that much anyway.

Q: What accessories do I actually need?

A: - Must have: Safety glasses, rotary attachment, LightBurn - Nice to have: Fume extractor, extra lenses, jig set - Waste of money: All the other random accessories they try to sell you ---
