SLA Fast Prototyping Machine

I. Procedure for USC internal and external users:

1. Users submit CAD design STL files to the Polymorphic Robotics Lab (attention to Professor Wei-Min Shen) at ISI (shen@isi.usc.edu);
2. PRL/ISI estimate (i) the cost in terms of the number of hours required to produce the parts, and (ii) the cost of the material;
3. User agrees with the estimated cost;
4. PRL/ISI produce the parts for the user and send an invoice to the user;
5. The user pays the cost to PRL/ISI.

II. Machine Cost Hourly cost for using the SLA machine is $186.79 per hour. (The detailed price breakdown is available at the Viterbi School of Engineering Dean’s Office from Linda Rock, Associate Dean of Administration upon request to lrock@usc.edu) III. Material Cost Material cost is estimated to be $423/kg if purchased through ISI, or $489/kg if purchased through USC campus, or whatever cost if the users purchase by themselves. V. Responsibility PRL/ISI will be fully responsible for the use and maintenance of the SLA machine. Appendix: An Informative Example As a small example to illustrate the cost, to produce an outer-frame shell for a regular cell phone (small but very complex) would probably require 0.5 hour machine time and 20g of material, if one produce a set of them (say 10) in a batch mode. So the cost for each shell when produced in a batch would be $186.79*.5 + $423*.02 = $101.86. To be economic for machine time, users are encouraged to produce parts in the batch mode.
