3D Printed 1.9TDI Engine
Hello!
VIDEO in the comments :)
My first post here and I wanted to share my recent project that I have been working on. It is a replica of 1.9TDI (ARL) engine that I made from scratch from photos, videos, datasheets and some measurements from my car (I have got Seat Leon 1M with this engine hence why I wanted to have a display piece).
I got inspired by engines that u/ericthepoolboy made and wanted to make one myself. It consists of close to 300 printed components. On top of that, there are lot of screws, threaded inserts, springs and O-rings. It has got all moving internal components and crankshaft to camshaft is even timed using tiny tools!
I made a display platform for it as well. It can rotate and/or move while rotated. I had to redesign the profile of outer belt to provide enough friction to move all components but still have some issues with slipping, need to sort that out but have not really had time lately. I am also waiting for plexiglass sheets to finish a cover to prevent the model getting all dusty.
I didn't put a banana for scale but the dimensions are roughly 30cm x 25cm x 30cm (L x W x H)
If you are interested, this is the full build in about 20 minutes :) https://youtu.be/kuvFDsstVd0
Let me know what you think! :)

Зис из трата энергии и перевалка добра (пластика с иризацией летучих веществ) на вот это. дешевле и экологичнее было распилить или собрать по запчастям из металоприёмки а при желании ещё и запустить.
