Work Area Size

The xTool D1 Pro 40W laser engraver has a work area of 430 x 348mm (16.9 x 13.7 inches). This can be expanded up to 909 x 430mm (35.8 x 16.9 inches) by adding xTool’s optional extension kit accessory.

The generous work space suits most personal laser cutting and engraving projects. However, users needing to work with very large materials may want to consider an industrial model instead.


Thanks to closed synchronous belts and all-steel wheels, the xTool D1 Pro 40W laser can operate at rapid speeds up to 400mm/s. This yields higher productivity than comparable machines.

For example, xTool found that their D1 Pro 40W could engrave a 100mm slate tile in just 5 minutes 47 seconds. Other 20W laser engravers took over 13 minutes to complete the same task.


In addition to speed, the D1 Pro 40W also excels in accuracy and precision. Engraving/cutting accuracy reaches 0.0004 inches while repeatable positioning accuracy goes down to less than 0.0007 inches.

This Incredible precision stems from multiple factors:

  • All-steel wheels & shaft (3X longer lifetime, 100,000x sliding capacity)
  • Closed synchronous belt (minimizes sliding deviation)
  • High-performance stepper motors and drivers

As a result, users can have complete confidence when working on intricate designs or projects requiring many repeated laser passes. This Engravers Accuracy really makes it remarkable.
