> [!INFO] Tags > #machine/3DPrinter Our space currently mostly operates [[Printing Technologies| FDM]] printers from Prusa and Bambulab. However, we also have resin and continuous fiber machines for advanced projects. # Getting Stuff Printed/How We Work Processing for our machines is generally done by the Interns of the space. We're happy to walk you through the steps, but to keep the machines safe we don't allow most students to slice for the machines. Just bring us your files and we'll handle it. ## File Types Accepted We accept `.stl`, `.3mf`, and `.step` files. Premade models can be found on [Printables by Prusa](https://printables.com) and [Makerworld by Bambulabs](https://makerworld.com) Designed parts can be exported from any CAD software of your choice like Solidworks, Fusion, or Onshape. > [!NOTE] Solidworks Exporting > In Solidworks, please export these files via `file > save as` and choosing `.stl` from the filetype dropdown. Name it something useful, like 'JohnSmithMotorBracketV3.stl' **NOT** 'part1.stl' or similar. It can also be helpful to increase the resolution in the Save As dialogue box via `Options... > resolution > fine > ok` ## Payment There is a standard rate of $0.04/gram of plastic. We charge this through an online payment processor which means you need to have card details on hand or saved to your phone. We cannot accept cash payments in the space, though cash payments can be made to the school [Cashier's Office](https://www.suu.edu/cashier/) if necessary via the charge code `MKRSPC`. However, we also offer **free** prints to people that work hard to design and produce their own parts (see below). > [!NOTE] Free Print Requirements > - [ ] .STL or .3MF file > - [ ] .STEP file > - [ ] 3-view blueprints in PDF format (fully dimensioned and notated). > - [ ] PDF bill of materials when applicable. > [!NOTE] General Printing Rules > - Any print can be rejected at intern's discretion > - Engineering projects will be given priority > - Batch prints will be done one at a time. > - Exotic materials available with approval only. > - Payment covers one reprint due to design flaws. If it fails twice, your part needs a redesign. > - No items that violate school policies (just use common sense). # Our FDM Machines ## Bambulab A1 (x3) ![[bambu-lab-a1-1-pc-700537-en.png]]The A1s serve as a daily workhorse printer great for PLA and PETG prints. They have a build volume of **256x256x256mm | 10x10x10"**. ## Bambulab H2D ![[621c418e-622e-4c86-ab45-351c437b0f39.webp]] The H2D serves as our FDM printer for advanced materials. It has **2 nozzles**, for integrating different materials into a single print. It also has a build volume of **320x320x325mm | 13.77 x 12.59 x 12.79 inches** (with some extra space on either side that can't be reached by both nozzles, so only some prints can reach there). It's very capable of printing ABS, nylons, and more. ## Prusa MK4S (x3) ![[75085d9d-2866-4522-8f74-bb74b341b495.jpg]] Our Prusa machines are mostly utilized for fast, small parts. They are all equipped with high flow nozzles and have a fast startup sequence so they pump out plastic very quickly. Build volume: **250×210×220mm | 9.84×8.2×8.6 in.** ## Markforged MK2 ![[markforgedMK2.png]] This printer reinforces carbon fiber nylon parts with a continuous strand of fiber (either carbon, fiberglass, or kevlar). This can make unique directionally strong parts. Very expensive to run, this machine only runs parts that have been thoroughly tested and require additional strength (generally capstone or engineering club projects). # Resin Printer ## Formlabs Form 3 ![[formlabs-form3-01_2_1_refurb.jpg]] Capable of many different resins (flexible, high temp, esd, etc), this printer is **very** expensive to run and is only available upon request/offer for parts and projects that would benefit from its unique capabilities. > [!ATTENTION] Miniatures > DND, Warhammer, and various miniatures/figurines do not qualify as suitable parts for the Form3. These will not be printed unless you designed them and at the discretion of Makerspace Interns.
