FabLab Spring 2021 Catalog The FabLab is an on-campus digital fabrication resource for the RIT 3D Printing Print a model for your thesis, a part for your car, community. With the right files, you or a prototype of your design. We offer a variety of can 3D print, CNC, laser engrave or colors and build volumes for both functional and laser/waterjet/plasma cut your designs aesthetic materials. without missing a class. Just submit your files at the ticket portal (linked Includes two processes: FDM and SLA 3D Printing. below), fill in some details, and we’ll For differences between the processes please see handle the rest. the section below. Pg. 3 - 7 Location Booth 7A- A620 Hours Laser Cutting Sunday - Saturday, 9 am - 5 pm For laser cutting, we limit stock thickness to 0.25” for cutting up to 48” x 48”, while etching or Payment Method engraving is limited to 5.00”.

The router is free to use, just remember to drop your stock off. Pg. 10 WaterJet Cutting Our Waterjet can cut any material up to 0.5” within a 12” x18” work envelope, but cannot engrave or etch. Pg. 11-12 Plamsa Cutting Our CNC plasma can cut mild steel, stainless steel, aluminum, brass, and copper up to .75” within a 48” x 48” work envelope, but cannot engrave or etch. Pg. 12 1 Ready to make something? Great! Now you need to submit a ticket to the FabLab Submit a Ticket Service Desk. You can access it with the link on the left but before you do, there are a few things we need to cover. Location Booth 7A- A620 Create a Ticket Please submit all files under one ticket. Submitting multiple tickets, including Hours tickets created by responding to a ticket via email, will be closed and consolidated Mon - Sun, 9 am - 5 pm. within a single ticket. Payment Method Payment Tiger Bucks The FabLab only accepts Tiger Bucks; no cash, credit or debit cards. Prior to pickup, double-check your balance. If you do not have Tiger Bucks: login to Ticket Portal eServices, click on the “Dining Accounts” tab, then in the “Add Funds to Dining http://fablab.cad.rit.edu Accounts” section, and select your Tiger Bucks account. Follow the credit card payment process and after you receive an email from eServices, you’re all set to checkout. We ask that customers pay for their ticket once it is completed and ready for pickup. This allows us to print your model as best we can and charge you accordingly. Delinquent Tickets If a customer abandons or refuses to pay for a model, they will be blacklisted. ‘Blacklisters’ may still submit tickets to the FabLab, however they must first pay all outstanding balances upfront before any new quotes can be generated. Turn-Around Once we have your file and printing specs, all you have to do is wait! Look out for emails regarding updates to your ticket’s status—including possible complications with your file, or when your model is ready for pickup. Because any process could take as little as a few minutes or as long as 5 days we can only give minimum turnaround time per process. That means it is unlikely that your ticket will be finihed quicker than the following times: 3D printing: 3 Days Laser Cutting: 24 Hrs CNC Cutting: 2-3 weeks Waterjet Cutting: 2 Days Plasma Cutting: 2-3 weeks All sales are final. We do not charge for failed prints, but will charge for models that have been printed after you’ve updated your CAD. 2 MATERIAL COLOR/NAME RESOLUTION PRICE FDM Materials (µm) Fused Deposition Modeling (FDM) is PLA Black 150, 200 2¢/g great for making rapid prototypes, Single or Dual Extrusion human factor models, functional parts, Grey 150, 200 2¢/g even moulds and jigs.

Use Features these examples to guide your design process, thereby increasing the likelihood of your design printing successfully. Specialty materials like TPU filament or Ceramic resin have a greater chance of deviating from tolerances beyond +/- 3%. Before committing to a special filament, consult with a FabLab 3D Tech or the manufacturer for design and tolerance tips.

CAD software enables us to swiftly turn ideas into actionable concepts. 3D printing, unfortunately, does not offer the same degree of fluency.
