Water-jet Cutter and Fast Prototyping Methods

Water-jet Cutter

Overview

The Maxiem1515 allows for the quick and easy cutting of 2-D profiles from CAD drawings. The Intelli-MAX software accepts DXF format profiles generated by most CAD software. It works extremely well for sheet metal parts and for complex shapes in 2D in materials up to ~150mm thick (50mm for steel). The kerf is approximately 0.8mm and the cutting area is 1.5m x 1.5m.

Videos showing basics of creating tool-paths and operation of similar models of cutter can be found here.

Basic Operating and Start-up Instructions for the Maxiem1515 can be found here.

Software Download and License

  1. Request a license: Intellimax License Request Form
  2. Set up a UBC VPN connection (see link to UBC IT Service  VPN to get a myvpn utility)
  3. While signed in to the VPN, download Omax software .zip file from: https://depot.mech.ubc.ca. Login using your CWL ID and password and browse – you will find the omax_intelli-max folder and the zip files therein. To access the “Depot”, you will need a MECH/PACE account. If you are unable to log onto “Depot” it is likely your account has not been registered. Details for account registration is given in http://technicalservices.mech.ubc.ca/it-services/mech-it-account-management/.  The download site and accounts are controlled by APSC-IT Services. Please contact APSC-IT Services at http://web.it.ubc.ca/forms/apsc/ if you are having trouble.
  4. Watch your inbox for an automated reply from Omax once your license request registration and eligibility is verified (only registered Mech students will be authorized; turnaround time is up to 5 business days).
  5. Once you get your authorization, click on the link in the email and select the Intellimax STANDARD version. Open Intellimax Make software and click on Register Software in the toolbar at the top of the window. Copy (ctrl-c) the 5 digit code generated by the Omax Make application and paste it into the appropriate window in the authorization email window. This should generate a long alpha-numeric code. Copy and paste this code into the appropriate space in the Omax Intellimax application.

Cost of Operating the Water-jet Cutter

This rate is for use of the machine only and applies only to actual cutting time.

Course work, department research, Mech student teams:                                                     $1.00/minute

Service work for other UBC departments and MECH student personal use:                    $1.50/minute

Commercial work and service work for non-UBC organizations or individuals is not permitted unless a service contract has been established via the University Industry Liason Office.

Personal use of the water-jet by registered Mech students for self-education is permitted on a limited basis. This must not be contract or service work for a third party. Costs should be paid by the user via cheque payable to: The University of British Columbia and the code HDNW along with the date of entry on the Payment Form should be placed in the notes field on the cheque.

 

3D Printers

Overview

The Student Shop has fused deposition modeling style 3D printers set up with ABS or PLA filament installed.

  • Afinia  479/480 – ABS only; filament is already installed.
  • Monoprice Mini Select – PLA only; filament is already installed.

In very general terms, ABS is tougher than PLA and glues easily with ABS plumbing cement. PLA tends to be slightly brittle but does not suffer as much from shrinkage issues as ABS.

Users are to report how much filament they have used on the shop’s reporting form. Filament cost is $0.04/gram.

Bring a USB stick with .STL files to load and run on the host PC or download and install software as needed (see below) to use your own PC to generate G-code files or to run the Afinia software.

Printers can be reserved and are accessible for setting up and starting jobs during Student Shop hours. Jobs that run after closing time are typically picked up at opening hours the following day.

For Afinia printers:

  1. H479/H480 Build volume 120mm x 120mm x120mm; preferred filament 1.75mm ABS,  nozzle size is 0.4mm and highest resolution is 0.15mm;
  2. Build sheets are perforated FRP treated with ABS glue on the build side. These are provided at the printers. Be sure to place the build sheet the correct way up.
  3. Users need to supply models in .STL formats (all 3D CAD software can export this type of file) and can bring a USB stick to the host computer or use their own computer to run the machine via a USB connection (need to install the Afinia software; see link below). Once the model file is sliced and downloaded to the printer, the USB can be disconnected.

Note that these printers have shrinkage issues with the ABS. Long, continuous sections should be oriented vertically to reduce this problem.

For Monoprice printers :

  1. Build volume 120mm x 120mm x120mm; preferred filament 1.75mm PLA, nozzle size is 0.4mm and highest resolution is 0.06mm.
  2. Build sheets are clear smooth polycarbonate provided at the printers. Tape or adhesive is not necessary.
  3. The printers operate on G-code files which you can generate from STL models using 3rd party software such as Cura. A version of Cura is installed on the host PC and you can generate G-code files from there. Load the G-code onto a micro-SD card to run it on the printer. A card and USB adapter for transferring files to the card are available at the printer.
  4. If you want to speed things up, you will need to install and run slicing software on your own PC. Monoprice recommends using Cura software. A version of Cura that shipped with the V1 printer is available here. Refer to the user manual below to ensure that you set the installation parameters in Cura accordingly. IMPORTANT: Nozzle print and bed temperatures set when generating G-code files should be kept below 200 degrees and 40 degrees C  respectively (not the 210 and 70 indicated in the default settings in Cura ) to minimize problems with filament softening and jamming ahead of the nozzle.

Atek Bantam 24 Ton Press Brake

Here are links for the dimensions and capacities of Atek Bantam 24 Ton Press Brake.

Tooling list (under development)

 

Brown Boggs Connecticut Brake

This bending tool lets you make up to 90 degree bends in sheet metal parts up to 16 gauge (1.5mm) thickness. It is relatively easy to use for simple bends and requires less setup than the Atek press brake, however it is comparatively limited in bending capacity.

SIP Weldmate 15KVA Spotwelder

This is a simple to use, foot-pedal operated welder that makes joining of steel and stainless steel sheet metal and wire stock fast and easy to do. Special electrodes are available for welding studs and nuts to sheet and plate to create strong threads. Basic operating instructions can be found here (under development). Refer to this video for more insight and inspiration.
