In this page you will find Pärnumaa Vocational Educational Centre DIY 3D printer.
When we were designing our printer, we use our know-how and experiences from Turkey, where teachers who carry out project work, assembled their version of the homemade 3D printer. Our base and most of technical drawings are found in "DIY 3D printer" page and in its submenus.
Like always, when a lot of engineering masterminds are together, we made some improvements (at least we hope 🙂 ).
All the minor observations and modifications are described below. Also all the drawings in CAD are included. Maybe you will find some of them useful or find inspiration to change your design.
Next we manufactured heatbed levelling screws and attached mirror glass for heatbed.
Glass costs about 20 EUR in our local glassshop, but it looks very good :)
We used 6 levelling screws instead of 4. In that way we got mode adjusting properties.
For lever adjuster springs, we used ebay springs for that.
Because we used thicker rails (20x20x1mm) we had to use linger polts. They don't make M3 polts anymore, so we used M4 polts. Thatś why we made out our own adjuster screws, to accomodate them to M4 nuts.
That was real life example, how in big machines everything is connected and everything must be considered when making some changes.
Our printer is almost ready. We have done first prints and it just needs a little adjusting and programming.
All levelling was fine at first - that shows that our tolerances when assembling were very little.
We had to do little more programming, to make menus more custom and intuitive to use.
Will we make a new one? .... of cource we will 😊. We have ideas for many new printers!
We also have Polish team 3 colour printer drawings and so on...
We are just in the beginning .....
