Furthermore, Glowforge provides specially designed materials known as Proofgrade materials for its laser cutters.

These are high-quality materials with uniform density, making them ideal for laser cutting and engraving projects.

Proofgrade materials are sized to fit your Glowforge laser cutter, and they also work well with other CO2 laser cutters and engravers. 

These materials have a protective film that prevents them from unwanted smoke and burn marks during the cutting or engraving process.

You can remove the protective layer from your finished product, after completing the process.

Furthermore, Proofgrade material comes with a QR code sticker, which enables Glowforge Pro to scan the code and set the optimal parameters automatically.

5. Software

Glowforge Pro comes with a dedicated browser-based app that you can use to import design files from any CAD software that exports JPG, PDF, PNG, and SVG files.

Although you cannot create design files in the Glowforge app, it provides some basic editing features to optimize the design for your workpiece.

After optimizing the design for your workpiece, you can use the app to set the laser parameters (power, speed, lines per inch, number of passes, etc.) for the cutting/engraving process.

Furthermore, Glowforge provides a dedicated smartphone app that allows you to control the laser cutter from your smartphone.

You can select an image from your smartphone’s gallery and add it to the design for engraving process.

This app is loaded with free graphics and templates that can be readily used for cutting and engraving projects.

You can also subscribe to Glowforge Premium via the app, which will provide access to unlimited design templates and advanced tools to optimize your designs.

It also provides unlimited storage for all your designs and supports DXF files.

6. Additional Features

Glowforge Pro is a feature-packed laser cutter that offers various advanced features to enhance its safety, efficiency, and productivity.

Air Assist

Air assist is used to blow the molten material out of the kerf thereby increasing the cutting speed.

It also blows the smoke and debris away from the focusing lens, thereby preventing it from damage and improving the quality of the cut.

Furthermore, it reduces the risk of fire by minimizing the heat-affected zone (HAZ) and keeping the temperature under control.

Glowforge Pro has an in-built air assist which eliminates the need for an external compressor.

This improves the cutting speed and enables you to produce clean cuts with a good surface finish.


The Glowforge Pro comes with two in-built cameras.

A wide-angle camera mounted on the lid, allows you to view the entire printable area to monitor the process.

This camera provides a live feed of the work area, thereby facilitating optimization of the design by placing it accurately on the workpiece.

The second camera, mounted on the laser head, is a macro camera. It provides close-up information for autofocus within 0.004” (0.1 mm).


Laser focus is an important parameter that ensures clean cuts with minimum heat-affected zone and narrow kerf widths.

However, setting the optimal laser focus can be difficult to achieve manually.

The macro camera of Glowforge Pro, scans the workpiece and helps in setting the optimal focal length automatically.

A de-focused laser is generally used for performing sub-surface laser engravings in acrylics.

Therefore, Glowforge Pro also provides the ability to adjust the laser focus manually and get the desired cut/engraving results on the workpiece.

LED Lights

The Glowforge Pro provides an excellent lighting system.

There are two internal LEDs that provide broad illumination for the cutting area.

It also features lights under the lid, which provide illumination not only to monitor the cutting/engraving process but also to facilitate the autofocus feature in dark environments.


The Glowforge Pro is certified to Underwriters Laboratories (UL) standards.

It consists of various safety sensors that detect and inform about irregularities such as unwanted movement of the laser cutter, overheating, and abrupt changes in the speed of the fan. 

In addition to the above, Glowforge Pro comes with Pro shields, that cover the passthrough slots to ensure that nothing comes in or out through them, when not in use.

Gowforge Pro comes with a detachable metal crumb tray that collects the dust and debris produced during the cutting and engraving process.

However, it reduces the maximum workable thickness of material from 2″ to 0.5″.

This means that, when using the metal crumb tray, Glowforge Pro can handle workpieces with a maximum thickness of 0.5″.

Cooling and Ventilation

The Glowforge Pro has an enhanced solid-state thermoelectric cooling system that allows to operate it for long runs without overheating.

It comes with an inbuilt exhaust fan and an 8-foot long exhaust hose that can be used to dispose of the fumes away from the work area.

The exhaust duct is 4″ in diameter and can easily connect with any standard inline exhaust fan to enhance its performance.

Proofgrade Materials
