Compressed Air Engine

From the creator

Who knew that 3D printed parts could be made to such tight tolerances! I'm very new to experimenting with ABS acetone smoothing, so this was a great project to start with! STL files are available to my Patreon supporters: https://www.patreon.com/tomstanton 3D Printer settings: Nozzle diameter - 0.2mm Filament diameter - 1.75mm Extrusion width - 0.25mm Layer height - 0.1mm Top solid layers - 6 Bottom solid layers - 6 Side walls - 6 Outline direction - Outside-In Infill - 25% (honeycomb) Material - ABS Nozzle temperature - 240C Bed temperature - 60C Cooling - OFF Printing speed - 1800mm/minute (Correction from video) Other parts required: 1pcs Spring (outside dia: 3.18mm, free length: 12.7mm, wire dia: 0.51mm) 1pcs M4x30mm bolt (this can be any desired length) 3pcs M2x20mm bolts 1pc M2x bolt 2pcs 604-ZZ bearings 2pcs 3mm brass collars (these can be cut from brass tubing with inside diameter of 2mm and outside diameter of 3mm) 8mm inside diameter PVC tubing (for air supply) A propeller of some sort will also be required, probably something around 5-8 inches in diameter will do the job. Disclaimer: If you wish you 3D print this engine, do so at your own risk. Working with high pressure air is DANGEROUS and I hold no responsibility for your actions. All parts were printed to the highest strength possible and I can't guarantee that your parts will be the same. So please test the engine behind a protective cover and only to low pressures below 30psi. Sponsored by 3D Printz UK
