First Useful 3D print

Today I finished my first usefull 3D print. The machine you see on the left is our coffee machine. Once in a while it needs cleaning and then there is water coming from the two nozzles left and right. Since there is not much space and it is quite a lot of water coming out of it, my wife usually has to pay attention since she has to empty the stuff she used to put under there half way. But it always is a bit messy. So we came up with the idea to make custom made compartments to hold the water.

As you can see in the picture on the right this is quite a large object already for the printer. It also took about 20 hours to print each of them. I designed the whole thing in Cinema 4D by the way and then exported to STL format. It is really nice to be able to make something like this just from software I already know :) Yesterday we did the first cleaning cycle with them and it worked out really fine. So another project finished.

It might look easy by the way, but I can assure you that this project took a lot of time. I also had a misprint where the PLA on the role got tangled :( So after 15 hours of printing or so, I could start all over again. So far every time I walk away from a print, something goes wrong. So I now plan my prints when I'm at home the whole day. So yes... 3D printing is nice. But it is time consuming and you need to know what you are doing. I'm really looking in to a more professional printer now, to hopefully get better quality and less hassle. I'll keep you posted :)

Another 3D Print - Star Wars Tie Fighter

Last week suddenly I heard a noise and I saw the extruder of the 3D printer I build hanging on only one screw. I tried to fasten everything again, but I had no luck what so ever. So before I could do any more printing I had to take the whole extruder apart, fasten the screws a but more and put it back together. That was a little setback, but unfortunately it didn't end there. After that I had to recalibrate the head distance and I had no luck in that.

The material just didn't want to stick to the heated print bed anymore. I tried cleaning with alcohol, rubbing it a bit with sand paper like I did before, but no luck. Then I started looking on some forums for a solution and I found one. Painters tape! Very cheap stuff that you can just stick on the print bed and after that I printed like a charm. I guess by now you would have guessed from seeing the pictures of a print in progress.

The model I printed came from ThingiVerse and it is a tie fighter from Star Wars. I really like the look of that model. It consisted of three separate printable parts that you eventually have to glue together. But before I got to this point there was some more trouble. After the first print was finished, the material was stuck to the painters tape so well, that I couldn't get it off. I printed in PLA and that is quite fragile, so I could not use too much force since then the material would break.

So again I went to look for a solution and I found one. The tip was to use a spraycan with compressed air, put it up side down on purpose so that the stuff coming out is frozen. This cools the object to quickly that it shrinks a bit and pops loose. And guess what? It worked :) I will go and look now though for blue painters tape since they say this is less sticky. So that is worth the experiment. All in all the model is done and I really like it. But again I found out that printing on a DIY 3D printer is not so easy as it looks. Ah well most important thing. It still works. Up to the next project.
