  • 【High Energy Cutting & Ultra-Fine Laser Beam】S9 Laser module uses the latest 5.5W laser beam shaping technology diode laser, it has an ultra-fine 0.06mm sharp compressed laser focus spot and 0.01mm engraving accuracy. With super cutting penetration and precision, he can cut up to 15mm thick wood, 10mm acrylic, 10mm plywood, easily carve ceramics and stainless steel, which is almost beyond the effect of 90W CO2 laser.

Convenience

Co2 laser machines are all very big and bulky as the Co2 tube requires much space. Installing a CO2 laser tube on your own CNC machine is also inconvenient as a result of its high size and the requirement of a sophisticated cooling system. Once we are talking about a garage, a workshop, or a small store – size certainly matters. Most small entrepreneurs or hobbyists simply do not have enough space. PLH3D-15W can be installed on virtually any CNC machine or even integrated into larger systems. With its lightweight, Aluminum body, the palm-sized PLH3D-15W weighs less than 800g, any CNC machine can operate it effortlessly.

A major advantage of Opt Lasers’ 30 W and 15 W laser systems lies in their small power consumption and the lack of requirement of a high voltage power supply. PLH3D-15W and PLH3D-30W achieve a power consumption of 52.1 W and 104 W respectively and can be powered with desktop power supply units. Their maximum power consumption is <85 W and <180 W correspondingly. In contrast, the electrical-to-optical power conversion ratio for CO2 tube lasers stands at approximately 7.5%. As such, a 30 W optical power CO2 tube consumes approximately 400 Watts of electrical power.

Durability

The lifetime of a laser diode stands for a period that extends until the output power of the laser diode is reduced by a factor of 2. Without the issues like random failures and aging faster at higher temperatures, the typical lifetime of the laser’s blue laser diodes is up to 20,000 hours while an average glass CO2 tube laser only has 3,000 hours.

445nm lasers absorb (read does its job on) well into Organics (wood, paper, leather) but not in any kind of plastic/resin/etc - CO2 lasers with the smaller 10600um wavelength absorbs better into all kinds of materials.
With plywood the problem is the PLY part of the word... its layers of organics (wood) glued together with Inorganic resins - so running a diode laser to cut plywood (even 3mm thick plywood consisting of three layers) fails because you "cut" (more like slowly scorch through though as the diode lasers are weak anyway) the first layer of wood, but then when it gets to the resin glue between the two layers, you get stuck and spend pass after pass trying to get through the glue line. But the time you did burn away the glue layer, all that heat has scorched the edge of the layer of wood above it beyond what it should look like.

I cut 1/4" birch plywood with my diode (15w) and have no issue. I run it at 500 mm/m at 10% with 10 passes. I am using an old 3D printer converted to a laser engraver/cutter. The laser module is from Amazon. It's an Annoy Tools 15w laser module.


Efficient】:Ultra-fine compression laser technology, spot area as small as 0.02mm², optical power 5.5W, faster engraving speed, higher engraving accuracy. Can engrave stainless steel, ceramics, seals, and can easily cut 3mm thick wood board, 2mm Acrylic.

ATOMSTACK 50W module laser head adopt the aviation aluminum TTL driver board with cooling fan can ensure continuous long time work. What's more, it has technology combines two 5W lasers into one beam, making the laser power larger and more stable. 0.08*0.15mm double compression spot light coupling technology makes engraving more powerful.

Can cut 10mm thick boards, only one time. Based on these perfect features, we believe that this module will be your first choice
