what about this Laser it's ok. Laser with TTL modulation 12VDC 405nm 150mw.
http://www.ebay.com/itm/New-12VDC-405nm-150mw-Blue-Violet-Laser-Diode-Module-with-0-20KHz-TTL-modulation-/130955440710
This laser WILL work with the LaserShark. The GND signal pin should be connected to the GND pin of the A, B, or C port you elect to use and the other signal pin connected to the A, B, or C signal pin.
You will still need a power supply for this laser however so make sure you procure this too.
if it's not too much trouble would you mind explain me abit about type Laser?
it's will be knowledge for anyone who want to make 3dprinter with laser by lasershark board.
I see on alieexpress
http://www.aliexpress.com/w/wholesale-ttl-laser-diode-module.html
many type and power for laser which type that i can use with lasershark.
I don't know laser it's have many detail.
1.what difference about green, blue, red laser or just color .or which color it's have affect with UV Cure Resin
2.abot nanometer (nm) I see many like 445 nm 658 nm 980 nm etc. what diference and which have affect with UV Cure Resin
3.and power about 150 mw 200 mw or 800 mw what difference more mw it's mean more power that resin will cure faster or not.
Thank you a lot

1. There are many different types of resins that can can be cured with light. Each type of resin is reactive to a different band (or multiple bands) of light frequencies.
Before you purchase a laser, you should review the resin you intend to use in order to select the best laser frequency. UV cure resins need ultraviolet light to cure. This means a laser between 100nm-400nm must be used.
Lasers that emit light in the visible light spectrum ~400nm-780nm such as green lasers (532nm) would not be good candidates for UV curing purposes.
2. the nanometer rating is the wavelength of light the laser produces. For example 532nm = green light, 445nm = blue light, and 658 = red light. If you search google for "electromagnet spectrum" you can read more about what wavelengths are where.
3. The power will affect how fast the resin cures. You should review your resin to identify the amount of power needed. If you obtain a laser that is not powerful enough the resin won't cure fast enough and if you obtain too powerful of a laser it may unintentionally over-cure an area or cure it too fast.
You must be
VERY CAREFUL when operating lasers more powerful than 5mW.
These lasers WILL cause eye damage if used improperly! At 150mW if the laser beam or a reflection enters your eye even for an instant you can be blinded. As you approach higher power levels even looking at the laser beam as it is bounced off non reflective surfaces can cause eye damage!
The smart and responsible thing to do is to ensure your setup is placed in an enclosure that blocks the laser light (direct and indirect) from entering your eyesight. You should also own a pair of laser safety goggles which are appropriate for the laser wavelength you are operating.
I cannot stress this enough!What is also important to know is that some of these lasers (i.e. those with wavelengths in the UV or close to the UV spectrum) are either not visible or appear very dim to the human eye even if they are very powerful.
Despite the laser beam appearing very dim or even invisible these lasers can still blind you!If you are new to lasers I would strongly encourage you to read the following:
http://www.repairfaq.org/sam/lasersaf.htmIn addition I would encourage you to search for laser safety classes taught in your area or discuss this with professional laser operators near you.
Never underestimate the cost of your eyes!
