+ 3 D Printed
+ I sent 2 jobs to 3 D print with ABS material to the Stratasys
+ machine. Each job was ~20 hours. The resolution is very good in the finished
+ parts
+ 
+ Laser Cu
+ I used Delrin 6mm thick with epilog 120watts. The settings were 20% speed
+ 100% power, 500 frequency. 4 passes each piece. The material gets heated
+ and need to take turns in cutting each piece. The fumes are very toxic. I will
+ try to replace some parts with acrylic.
