https://thegr5store.com/wp/Every laser comes with a calibration card telling you the wavelength (every laser is a little different - usually 650 to 660nm). Every laser runs on normal USB power (5v) which comes from phone chargers, USB cigarette adapters, USB batteries, computers, laptops, etc. Comes with 1 meter long power cord. You must supply your own USB power source.

This laser has 2 advantages over the cheaper laser I sell: larger beam and glass lens.

The glass lens means it is easy to clean without scratching. The other laser I sell has a plastic lens secured with a spring and the spring scratches the lens more and more every time you take it apart. This laser doesn't have any spring touching the lens.

Replaces Ultimaker2 teflon part. This is made of PTFE but it's a high temperature teflon. First there was regular PTFE (both Ultimaker and 3dsolex). Then there was "TFT" (3dsolex and soon after Ultimaker). Now there is "TFN". TFN lasts about the same amount of time as TFT depending on temperature. Learn More

Customized for your lens and laser: send me a mechanical drawing of the lens you plan to use and I'll make a custom holder for it. Similarly with the laser - usually all I need to know is the diameter of the end of the laser but if you send me a drawing or measurements I will try to make it fit nicely.

You will need an XYZ table which I also sell.

Hex driver included.

Colors of plastic parts most likely will not match photo (I use whatever colors are convenient). The white parts in the photo are nylon. The other parts are PLA which will melt in a hot car in the summer. If you need this to withstand high temperatures let me know and I'll add $10 to the price and give you one printed from PET or similar. Learn More

Insulator - for Ultimaker2 - goes between white teflon isolator and heater block (Olsson or Ultimaker). Learn More
