Sprinkler

▼This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printingPlease leave comments using the talk page. The course runs in the Fall semester. It is not open edit.

Conserving water is becoming more of an important issue in today's world. An open-sourced sprinkler attachment for a hose can lead to less consumption of water. Its main use is providing a low cost irrigation solution for small gardens. Urban farming specifically can greatly benefit from an open-sourced sprinkler attachment.

1. 3D Printer
2. 1.75mm diameter PLA (1kg ~ $25)
3. .STL file
4. Hose
5. Water Supply

1. MOST Delta RepRap or similar RepRap 3-D printer

Basic understanding of 3D printing

1. Download the STL file
2. Generate gcode via Cura, Slicer or another slicing software
3. Print the sprinkler head using the 3D printer
4. Screw the sprinkler head onto the water hose threads
5. Turn on water supply once sprinkler head is placed in desired area

• Assembly time estimate: under 1min

When printing the sprinkler head, set the infill high enough to eliminate unwanted leaking or spraying. Also ensure that the printer is extruding at the correct rate.

• Commercial Equivalent: $5-$20 https://www.google.com/search?q=sprinkler+head&safe=off&es_sm=93&biw=1920&bih=955&tbm=shop&source=lnms&sa=X&ei=6fl_VNfhGcyqyAT2r4HABg&ved=0CAgQ_AUoAQ&dpr=1#spd=16760520700473328747
• Sprinkler Head: 33grams of PLA at $25/kg ---> $0.83
• Percent Savings (using low end commercial equivalent): 83.4%
