If you own an xTool D1 Pro,  you might be wondering which laser module is the best fit for your needs. The decision between the xTool D1 Pro 10W, 20W, and 40W depends on your intended use, desired laser spot size, workspace, etc.

In this blog series, we'll break down the differences between the 10W, 20W, and 40W options and discuss their performance on various materials and how they fit various use cases, helping you make an informed decision.

In our last article, we compared the performance between 10W and 20W laser modules. And today, we are going to dive into the cutting ability of 40W laser module.

40W Laser Module Cutting Performance

The xTool D1 Pro 40W laser module is the world's first true 40W output octa-diode laser module for their xTool D1 Pro laser engraving machine. It combines light output from eight separate 5.5W laser diodes into one powerful laser beam, which has an optical output power of 40W. With the kit, you also get two spare lenses to keep the machine operating for a long time.

In addition, the xTool D1 Pro 40W laser module is much better at engraving at low power levels compared to the xTool D1 Pro 20W. A 40W laser machine is powerful enough to cut through soft materials like wood, leather, foam, acrylic, etc. The type of laser you use will significantly influence the materials you can cut. For example, you can cut glass with a 40W CO2 laser, but a diode or fiber laser of similar power can't do the same job.

In a nutshell, it is able to cut through:

• 18mm hardwood cutting in one-pass
• 15mm black acrylic cutting in one-pass
• 0.1mm stainless metal cutting in one-pass
• 3mm acrylic in approximately 1.5 passes at 600mm/min
• 10mm acrylic in only 6 passes;  For comparison, the xTool D1 Pro 20W module needed 14 passes.
• 10 mm (0.40") pine wood in 4 passes at 700 mm/min
• 10mm Poplar plywood board at 600mm/min clean without significant charring.
• 18mm Poplar plywood in 6 passes at 300mm/min. xTool D1 20W module wasn’t able to cut when we were testing it with an air assist.
• 36mm spruce plank in 7 passes at 300mm/min
• 17mm thick pine board in 4.5 passes at 600mm/min, and 2.5 passes at 300mm/min.
• maximum 40 mm (1.5") pine wood
• 0.15mm thick steel which is more than what the 20W modules were capable of.

 FAQ： How long does a diode laser last?

A typical diode laser used on laser engraving machines lasts for about 10,000 hours. This varies for different manufacturers, so for accurate information, read the product manual or contact the manufacturer.

So, which xTool D1 Pro laser module should you go for? Whichever option you choose, happy engraving, and have fun creating! 🌟
