Where is the I2P Lab at CSU?
We are in room B7B in the basement of the engineering building on CSU main campus, just south of the intersection of Meldrum and Laurel. Google Map.
What are the hours of the I2P Lab at CSU?
The I2P Lab is open from 10 am to 5 pm weekdays. During the summer we are open from 10 am to 2 pm on weekdays. We are closed weekends and CSU holidays.
Do you have to be an engineering student to have access to the lab?
No, anyone can have access to the I2P Lab if they take the required training workshop. To use the printers, you must also pay the lab fee.
What does the certification process look like in order to operate the printers?
What is the cost of using the equipment?
There is a lab fee required and users need to supply their own material, which can be purchased from RamTech in the Lory Student Center.
What is the cost of materials used in printing?
It ranges from $0.12 per meter to $0.87 per meter depending on filament type and user group. Our SLA printers use a specialty photopolymer that costs about $1.40 per gram.
How do I determine how much material my part will use?
A fast and easy way to estimate is to use your favorite software tool to determine the volume of the part, then assume 1cm^3 is approximately 1 gram. Filament is about 6.7g/m for 3mm diameter filament, and 2.5g/m for 1.75mm diameter filament. A more accurate estimate can be found by loading your mesh into the slicing software, then host software, or by using a .gcode preview tool, such as gcode.ws.
What is the limit of use? (how many units/how many hours per person?)
3 reservations per user per day, maximum of 8 hours per reservation.
What other FAQ/forums are available as online resources?
There is an IRC for RepRap. You can check that out by going to webchat.freenode.net and entering an alias (any name you want) and the room is #reprap. Fill out the captcha and click connect.
hackaday.com for discussion of interesting projects.
filament guide for a list of filaments available.
RepRap.org is ok, but a lot of the stuff there is outdated and they seem to have intermittent server issues so it is down a lot. Things include this pictoral troubleshooting guide, the RAMBo driver for windows and the search feature. There is an absolute goldmine of information there.
Here is a great troubleshooting guide with pictures.
If hexagonal is better, can I use Slic3r to create the g-code and print it on a Lulzbot mini without too many issues?
What percent infill would be best to achieve relatively high strength without being solid (to save on printing time)?
