Re: my first design - 18 years ago
I did say, that you will not a sufficient output with a dvd writer's diode. that is a good hint, you just ignored that. nope i did not i told you i have a 400mw laser pointer. wich dust melt plastic easly. i tested this a long time ago. i did extract diodes form dvd writers and they do exaclty the same. what you cant seem to corprohand is that this are ideas for now. and not yet been tested inby spoocke2 - Mechanics

Re: my first design - 18 years ago
diego as for one your comments arent construtive at all. second of all can you read what i said when i wrote i already did such experiment with a dvd writer laser. you need glasses i think. the design is my first its called a first brain wave prototype. if your brain can coprohand that omg. and you only know the outcome of this when you realy tested it. btw i do post a drawing of something in myby spoocke2 - Mechanics
Re: Crazy granule extruder idea - 18 years ago
I don't have any old printers here. I spent a little time searching for some, to no avail. Not everyone has access to such things. i cant imagine this my self. but okay you have a strong point there. on the other hand with this kinda printing i am thinking of some kinda water proof build area and as you print. it slowly adds water in it so you could build higher or even faster as the plastic beby spoocke2 - Mechanics
Re: my first design - 18 years ago
But then there's the need for a giant cooler not to blow the diode and you will have to take security measures not to blind yourself or get stinged. 1 watt laser omg your just need it to fuse not burn it lol. i have a 400mw red laser points ( with potentio meter ) on lowest input it already burns. step to a green 140Mw point laser wich arent that cheap but payable still. it will do the job. to cby spoocke2 - Mechanics
my first design - 18 years ago
i never done anything like this before. still its my first design i made. with a powder 3d printer you can print the most complex things as the powder layers will build its own support. none heated powder can be re'used. for the laser diode am still searching what would be the best. a red 150mw laser diode could be enough but not for white powder it would just reflect the light. one could add aby spoocke2 - Mechanics
