The Open Source SLS printer Willybot.  

Willybot is 

My name William + Robot = Willybot.

This is not the commercial name just call for the printer I have made.

This is not my job. This is my  hobby. So it takes time to develop and finish because I am very busy. But I try to do it for the open source people and the people who want to make the SLS printer.

I developed the sand SLS printer myself and gave the technology to Korean company. But the result is not good for me.

Anyway I want to make the  open source desktop SLS printer and the desktop metal printer such as Reprap.

I try to write my skill learned from the open source 3d printer. I want to share my knowledge from the open source.

This is not for the commercial purpose but my hobby.

DANGER DANGER DANGER

The laser system is very dangerous because the light can not be seen but the danger for the eyes and the voltage is very high so you can be died of the very high voltage.

Please keep in mind this. This is for the specialist and professional area.

The safety is your responsibility not me.

The system based on the below:

SLS based.

The low cost laser system : CO2 laser using glass tube.

                          From China but I bought it from US.

                          Normally I use the 40W CO2 laser.

                         Max is 150W ,2 years ago but I do not know.

                         PWM power supply

   If you want to make the metal printer, you can use the LED laser or the fiber laser.

Recoating system & Powder feeding system

The control system is based on the Arduino hardware controller.

The control Software for the SLS printer.

The added program of the sliced file.

 Because the FDM slicing sw does not have the Laser G-code.

Powder : The sand poweder from Japan chemical company.

         It is compatible with EOS S750 machine but the machine is discontinued.

        The first time I will develop for the sand powders. And then PA plastic powder and the metal powder.

        The sand -> metal -> plastic
