Hi guys, i doing research quiet a long time now, long story short my laser diode in form2 giving up and not really producing reasonable test print when i printing the OpticsTest.form (loosing focus)
After contacted formlab they told me this isn’t something that user can replace and i have to send the printer in for service. fees are 900euro +tax and wait couple of weeks.
This is kind of unreasonable for a $20 diode. specially when there is a high chance that they will replace my broken diode after i paid them more then 1000euro with a use one, as mentioning in there policy.
"Formlabs may use new, used, or reconditioned parts of equivalent or superior specifications in the repair of your machine. In some cases, and at its sole discretion, Formlabs may opt to replace a product with a new or refurbished product of equivalent or superior specifications. "
so i had some time and take the module out for a closer look. it turned out that the optics are fixed and the diode itself with PCB are covered with epoxy. i guess formlab dont really want the user to replace that $20 diode after all
anyway i have successfully extracted the diode and PCB with some minor damage that not compromising work.
(machine still works the same way before diode extraction.)
now i get to the point that i need some help to identify the diode itself.
so far i know for sure the following:
Output Power: 250mW
Integrated Photo Diode: NO (only form1 has PD in diode, as you can see it on pictures 2 legs connected only for form2)
Module number: LR|SC|03|16120175
PCB number: 003-0039-00-A
Would be nice to have more information regarding the diode itself.
like model number or Operating Current, LD Reverse Voltage, Allowable Reverse Current etc…
anything would be helpful.
Also yes i have aware that individually each laser diode is checked by formlab and calibrated to the machine. setting up focus and calibration is another day/post. Right now im on the diode identification part
enjoy the pictures
