In recent years, laser engravers have become increasingly popular among hobbyists and small business owners. However, for those on a tight budget, ultra-cheap laser engravers under $300 are particularly appealing. Below is an evaluation of safety and savings for such laser engravers:

General Overview of Ultra-Cheap Laser Engravers Under $300

• Basic Performance: Typically equipped with 5W or lower diode lasers, these devices can perform basic wood and leather engraving, with engraving depths generally around 1-2mm. Their work areas are relatively small, usually under 8"x8", and they often require manual focus adjustments.
• Functionality Limitations: They generally lack the capability to engrave metals and offer inconsistent cutting performance. Cutting thicker materials is challenging, and the engraving speed is relatively slow.
• Safety Concerns: To cut costs, these engravers often omit essential safety features like enclosures. During prolonged use, there is a risk of fire. In testing, 3 out of 7 units ignited materials. Additionally, 40% of the tested devices exhibited electrical issues within two months. Positioning errors of ±0.5mm are also common.

Recommended Ultra-Cheap Laser Engravers Under $300

• Atomstack A5: Priced at $279 when on sale, it features a 5W diode laser. Its actual precision reaches 0.08mm, includes an air assist nozzle, and boasts a more rigid frame compared to competitors. However, its maximum engraving depth is only 3mm, and it lacks a safety enclosure.
• Sculpfun S6: Available for $269, it uses a 5.5W diode laser. Its laser module is replaceable, it is compatible with LightBurn, and it produces surprisingly crisp lettering. The downside is its fragrant aluminum rails and the need for DIY ventilation.
• Two Trees TS2: Priced at $299, it features a 5W diode laser. It has an all-metal frame, comes pre-assembled, and includes a decent software bundle. However, its engraving speed is slow, and its documentation is poor.
• Two Trees TTS-55: With a work area of 300×300mm and a 5.5W laser head, it can engrave wood, acrylic, leather, and other lightweight materials. It also features a controller that integrates Wi-Fi and Bluetooth, enabling wireless control via a mobile app. That said, it lacks several key safety features, and its side-mounted Y-axis stepper motors limit the maximum size of workpieces.

Safety Recommendations for Using Ultra-Cheap Laser Engravers

• Add Safety Equipment: It is advisable to spend an additional $50 on an enclosure to enhance safety and $30 on an air assist pump to improve engraving and cutting quality.
• Choose Safe Materials: Use masking tape to prevent burn marks and opt for light-colored woods to achieve better contrast.
• Control Usage Time: Avoid prolonged continuous use. Most ultra-cheap laser engravers can only operate for 30 to 60 minutes before overheating.

When to Consider Spending More

If you need to cut materials thicker than 1/8", require more than 10 hours of weekly usage, or desire metal marking capabilities, it is recommended to save up and invest in a higher-quality laser engraver.

In summary, ultra-cheap laser engravers under $300 can meet basic engraving needs but come with certain risks and limitations. Users should weigh the trade-offs between safety and cost savings based on their actual needs. If possible, it is advisable to invest slightly more in a higher-quality laser engraver to ensure safety and achieve better engraving results.
