Buying & Comparison FAQs --- ## 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 --- ## Business & Money Making FAQs ### Q: How much money can you make with a laser engraver? **A:** - Hobby / side income: $200-$500/week - Serious part time: $500-$1,500/week - Full time: $3,000-$8,000/week These are real numbers from actual business owners, not theory. ### Q: What is the most profitable thing to laser engrave? **A:** By a wide margin: **custom tumblers**. 80% margin, $25 profit each, 2 minutes work each. Almost every successful laser business starts with tumblers. ### Q: How much does it cost to start a laser engraving business? **A:** You can start for **under $300 total**: - Tyvok P2: $149 - Rotary: $49 - LightBurn: $60 - 10 blank tumblers: $30 - **Total: $288** ### Q: Do I need a business license? **A:** It depends on your location, but in most places yes. It's usually $50-$100 and takes 30 minutes online. Well worth it to be legitimate. ### Q: Where do I get blank products to engrave? **A:** The most popular suppliers: - Amazon (fast shipping, good for testing) - Alibaba (cheapest for bulk) - Wholesale blanks suppliers ### Q: How do I get customers? **A:** The most effective methods (in order): 1. Word of mouth / referrals (#1 by far) 2. Local Facebook groups 3. Etsy 4. Google Business Profile 5. Cold outreach to local businesses ### Q: How much should I charge for custom tumblers? **A:** **$30 each** is the standard price. Discount for bulk: 10+ for $25 each, 50+ for $20 each. Don't go cheaper than $20 even for large orders. ### Q: How many tumblers can you do in an hour? **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 --- ## Final Note If you have a question that's not answered here, email us and we'll add it.
