The Difference You Can See.
From intricate lines to subtle grayscale transitions, experience the difference that finer engraving precision can make.
What to look for: depth in the shadows, clean highlights and smooth tonal transitions through the fur.
What to look for: whether thin lines stay separate and edges stay complete in dense, complex areas.
What to look for: legible edges on tiny lettering and clean corners in small logo details.

Smaller Laser Spot
Smaller Spot. Finer Details.
A smaller laser spot helps reproduce finer details and sharper engraving features, making intricate designs easier to bring to life.

Laser Spot Size · for the smallest design elements
A finer focused spot helps capture smaller design elements, delicate lines, and intricate patterns with greater detail.
The 38.1 mm focusing lens is optional. Spot size is not the same as final line width or resolution — actual engraving results vary depending on material, lens, focus, speed, power, DPI and processing settings.
Upgraded Optical System
Better Beam Quality. Better Engraving Results.
The integrated beam expander works with the upgraded optical system to help deliver refined engraving results, bringing out more visible details in bitmap images and intricate designs.

Powerful Cutting Performance
More Power. Cleaner Cuts.
Combine 70W CO₂ laser performance with stronger external air assist to tackle demanding cutting projects and achieve cleaner processing edges.
-
70W CO₂ Power
Built for versatile engraving and cutting across compatible materials, from detailed designs to thicker wood and acrylic projects.
-
Expandable Air Assist
The open M10 air connection lets you connect an external air pump for increased airflow, helping remove smoke and debris from the processing area and improve cutting results.
-
Up to 300 kPa External Air Assist
With a compatible external air pump, the air assist pressure can reach up to 300 kPa, depending on the selected setup.
Cutting thickness and edge quality depend on material type, thickness, power, speed, focus, lens and air assist setup. Maximum cutting results are measured on specific materials under specific settings and are not guaranteed for all materials.
Flexible Machine Design
More Room for Bigger Projects.
The removable base design gives you more flexibility when working with taller and thicker objects. Raise the machine as needed and explore more possibilities beyond standard desktop engraving.
-
Step 01Standard Setup
Fully enclosed desktop operation with the base installed for everyday engraving and cutting.
-
Step 02Remove the Base
Detach the base to open the bottom of the machine and raise it to the height your project needs.
-
Step 03Engrave Taller Objects
Work directly on thick wood, tall acrylic blocks, boxes and other oversized items.
Laser safety in open-bottom mode
The Class 1 enclosed rating applies only to the standard setup. Operating with the base removed changes the laser classification to Class 4: always wear certified CO₂ laser safety glasses (10,600 nm), keep others out of the work area, use appropriate shielding, and never leave the machine unattended.

FAQ
Precision Questions, Answered.
Everything you need to know about MEGAS optics, air assist and open-bottom engraving.
View Full DetailsWhat laser spot size does MEGAS 70W support?
With the standard 50.8 mm focusing lens, MEGAS produces a 0.05–0.07 mm laser spot. With the optional 38.1 mm lens, the spot can reach 0.03–0.05 mm. Final line width and detail also depend on material, focus, speed, power and DPI.
What is the difference between the 50.8 mm and 38.1 mm focusing lenses?
The 50.8 mm lens is the all-rounder: a longer focal depth that suits both engraving and cutting thicker materials. The optional 38.1 mm lens focuses to a smaller spot for ultra-fine detail — small text, intricate line art and photo engraving — with a shorter focal depth, so it works best on flat surfaces.
Does MEGAS support higher DPI engraving in LightBurn?
Yes. MEGAS works with LightBurn as well as Monport's M-Design Hub, where you can set the engraving DPI / line interval for image and fill modes. Higher DPI can capture more detail but increases job time — the best setting depends on your material and lens.
Can I connect an external air pump?
Yes. MEGAS has an open M10 air connection for a compatible external air pump. With the right pump, air assist pressure can reach up to 300 kPa depending on the setup, helping clear smoke and debris for cleaner cuts.
Can I remove the base to engrave taller objects?
Yes. The removable base lets you raise the machine and work on taller, thicker objects. Note that operating with the base removed changes the laser classification to Class 4 — wear certified CO₂ laser safety glasses and use a controlled, shielded work area.
What materials can MEGAS engrave and cut?
MEGAS engraves and cuts wood, plywood, MDF, bamboo, acrylic, leather, paper, cardboard, fabric and cork, and engraves stone, slate, glass and ceramics. Coated or sprayed metals can be marked with laser marking spray. Never process PVC or other chlorine-containing materials.
