They are different categories of machine for different jobs. A galvo system uses two mirrors to scan the laser beam over a small fixed area at very high speed, which is why galvo machines mark a small image in seconds where a gantry takes minutes. The trade-off is field size: galvo is built for items that fit within roughly 110 to 300 mm. Gantry CO2 machines move the laser head physically over a much larger bed (400 mm and up) and can cut through thick acrylic and wood, which a galvo cannot.

If your work is small marking and shallow engraving on tumblers, leather, signs, and gifts, the HT-35W galvo is faster and produces tighter detail. If your work is cutting full sheets of acrylic or large wood signs, you want a CO2 gantry like our HT-460 instead.

Three reasons. First, lifespan. A glass CO2 tube typically lasts 6,000 to 10,000 operating hours before output power has dropped enough to need replacement, and a replacement tube is a significant cost. A DAVI metal RF tube is rated for 20,000 to 30,000 hours and can be re-gassed at end of life rather than thrown away.

Second, power stability. Glass tubes lose output gradually from day one, so the settings that worked last month produce shallower marks this month. Metal RF tubes hold rated power consistently across the lifetime, so your saved settings stay reliable.

Third, beam quality. The metal-body design with all-internal optical mounting produces a tighter beam mode (better M2) than a glass tube, which translates to crisper edges on small text and finer detail in shallow engraving.

The 10,600 nm CO2 wavelength is strongly absorbed by organic and coated materials. The HT-35W handles powder-coated tumblers and drinkware, vegetable-tanned and chrome-tanned leather, real wood (softwood and hardwood), bamboo, MDF, paper and cardstock, cast acrylic, glass surface frosting, anodized aluminum coating removal, painted metal, slate and stone, ceramic surfaces, fabric and felt, rubber, and most non-PVC plastics.

It cannot mark bare uncoated metals. For stainless, aluminum, brass, titanium, and other bare metals, you need a fiber laser instead.

For a starting or part-time tumbler business processing 10 to 30 tumblers a day, yes. The 35W removes powder coating cleanly on a single pass at sensible speeds (around 1,000 mm/s at 30 to 50% power, calibrated for your specific coating). A typical 12 oz tumbler design completes in 60 to 90 seconds.

If you are running a full-time production tumbler operation processing 50 or more cups a day, the 60W is the better economic choice because the cycle time on each cup is roughly half. But the 35W is fully capable for the volumes most buyers actually run when they are starting out.

Yes. LightBurn Galvo edition is fully compatible with the BJJCZ controller in the HT-35W. Many users prefer LightBurn because it has a friendlier interface for rotary calibration and runs natively on Mac as well as Windows. EZCad Original ships with the machine at no extra cost; LightBurn is a separate purchase from LightBurn Software.

One important note: the markcfg7 calibration file shipped with your machine works only with EZCad. When you switch to LightBurn, you do a one-time lens calibration in LightBurn itself (around 15 minutes following their guide). Always keep the original markcfg7 backed up before making any changes.

The standard 110 x 110 mm lens is the right choice for most buyers. It gives you enough field for tumblers (with rotary), small leather goods, dog tags, signs, jewelry, and most personalization work. Smaller lenses (70 x 70 mm) produce a tighter spot for very fine detail but limit what fits on the bed. Larger lenses (175, 210, 300 mm) handle bigger items but sacrifice spot tightness and effective power density.

If your primary work is full-wrap tumbler designs or larger leather panels, the 175 x 175 mm is a good upgrade. If you need flexibility, you can order an extra lens with the machine for around $200.

The HT-35W comes with an 18-month full warranty. If anything except the laser source fails during warranty (galvo head, controller, Z motor, lens, cables, power supply, foot pedal), we ship a free replacement part to your door. You do not need to send the failed part back to us. We cover all shipping costs.

The DAVI laser source itself is covered by DAVI's manufacturer warranty, which we administer for you. If the source fails, we coordinate the return to DAVI, cover both-way shipping, and ship you a working source as soon as DAVI processes the claim. After warranty expires, you have lifetime email support at info@haotianlasers.com for setup help, settings advice, and software questions.

Free DDP shipping to US, Canada, and EU buyers. DDP means Delivered Duty Paid: all customs duties, import taxes, and brokerage fees are included in the price you see on the product page. Your machine arrives at your door with no additional charges. Estimated delivery is approximately 30 days from order, including production lead time.

For all other countries, free CIF shipping worldwide takes approximately 12 to 14 days, but the buyer is responsible for any duties and import taxes in their country.
