Make a DIY Waterjet Cutter From a Cheap Pressure Cleaner

In my youth, I used to work at a local car wash place. If you traveled trough Balkans you probably saw many of them, and they all use handheld pressure washers. When I saw this video it reminded me of that time and I thought you guys would enjoy and find something useful in this project.

Ben Krasnow used a very cheap pressure washer and attached a DIY abrasive sand container combined with AccuStream professional cutter head to make a low-cost DIY waterjet cutter.
It can cut thin aluminum, wood, and plastics. it looks like the cuts are very precise and controllable. In water only mode it cuts trough soft materials like foam.

Here is the full video with all the details.

Next step would probably be to mount this cutter on a CNC gantry and turn it into a fully computer controlled machine.
Since there are much more powerful pressure washers, like the Karchers I used, this could be made into a more capable device.
With right settings, it could potentially cut plastic 3d printed parts or use it as a sand blasting device for surface finishing.

3D Printable Control Unit with 32 Programmable Keys

Here is a very useful DIY 3d printable control unit that can send custom g-code scripts and macros via 32 programmable keys. It can be used on almost any machine that uses g code, like CNC mills, 3d printers, laser cutters and other. It is powered with Arduino Nano.

The "Gcode Sender" was developed and released by James Sierra. Here is his description of the project:

This project is very much like using Pronterface or Repetier Host manual control to send gcode instructions to your printer while connected to the computer via USB cable, but instead using an Arduino Nano connected to a small keypad to send the Gcode scripts/macros.
Gcode sender is intended to work for 3D printers as well as a CNC mills and laser engravers. Any machine that uses gcode.
This setup allows one to send highly customized gcode scripts/macros to the printer with a push of a button. I've tested all of the scripts I included in the sketch. Any one of them can be replaced or edited.
In the sketch, i tired to include a lot of comments to make it easier to tweak the code to suit your own needs.
Communication between Gcode Sender and printer is through serial communication (Tx, Rx). On RAMPS style boards the AUX-1 port can be used. Specifics on wiring can be found in the Wiring.zip file. Be sure that Tx out wire on the Gcode Sender is connected to Rx on printer and Rx is connected to Tx. In Repetier firmware, I had to enable Bluetooth serial port to make use of the AUX-1 port.

Why Millebot?

Millebot is a large 3d printer that lives inside a shipping container. The idea behind it looks interesting...

... BUT

Why use this strange paste / foam for 3d print? and then mill it afterwards?

Building retainer walls for anything? Are you serious?

The operation will need a LOT of electrical power, material and overall complex logistic support.

Nice try, but I think it still needs a use case and overall technology improvements.

Someone note in the comments that this is a CNC router. So, what is a different between CNC mill and CNC router?

"A CNC router will usually have a large X and Y range and short Z... A router will typically be able to do soft materials like wood, plastic, and maybe aluminum... But overall, it won't have the most rigid structure (like this one which is 3d printed)

A CNC Mill will have a relatively smaller X and Y with a larger Z than a router... A mill will be able to cut hard materials like steel... And thus will have a very rigid structure so that it can accurately cut those materials."

Iteration and Repair of Existing 3d Printed Objects Without Re-printing

I have seen the future! Changing already 3d printed objects without the need to 3d print them again! Group of researchers developed this method that uses multifinctional 3d printer with laser 3d scanner and CNC milling head to make changes to the already 3d printed object to add or subtract from the previous design.

You can also repair failed prints and make changes on the fly. The developers call this system "Patching". It saves a lot of time and material. Imagine spending few minutes repairing object that would take hours to reprint!

Seeing it in action is very impressive:

Hopefully this technique will find wider application and adoption on mainstream machines and design/control software.

Project description:

Personal fabrication is currently a one-way process: Once an object has been fabricated with a 3D printer, it cannot be changed anymore; any change requires printing a new version from scratch. In this paper, we propose a different approach: instead of re-printing the entire object from scratch, we suggest patching the existing object and replacing only the unsatisfactory parts. This saves material and reduces waste, making a first step towards more sustainable 3D printing.

This project is a collaboration between Hasso Plattner Institute and Cornell University.
