Laser Upgrade Kit PLH3D-2W for Prusa i3 MK3S printers

A set enabling the connection of a2W laserheadtoi3 MK3S Prussia.Thanks to this extension the printer will gain the possibility of engraving and cutting on such materials as wood, paper or leather. The headweighs only 70 g, so it does not additionally load the extruder structure on which it is mounted. It also does not require an additional cooling system.

Installed laser head PLH3D-2W.

The PLHD-2W head is equipped witha 450 nm laser diodeand a high resolution lens. Its focal length is in the range from 20 to 120 mm. The device uses a built-in printer power supply.

The PLH3D- 2W laser head.

Analogue device power control

The power of the PLHD-2W can be adjusted in an analogue way.At individual voltages the power takes the following values: 0 V - laser off, 2 V - about 40% power.TTL technologycan be used here, using voltages from 0 to 5 V.

Power regulation with PWM

For PWM power control, the basic frequency should be in the range5 to 10 kHz.

PLH3D-2W laser head.

• Fasterprototyping of PCBs, thanks to a small laser spot that allows for illuminating photosensitive surfaces
• Thermal protectionto protect the device against overheating by switching it off when the operating temperature is approaching a critical value
• Lens protectionagainst soiling
