Assembling a CoLiDo DIY 3D printer, part 1

Main parts

As most of you know, I am not an engineer, despite my lofty ambitions of tinkering with all sorts of things.

So, the other day Jouko Lehtomäki from Suomen 3D-ratkaisut, the partner company of my university Haaga-Helia, brought us a brand new CoLiDo DIY printer in a crate. He said it’d be a piece of cake to assemble, and asked me to film a timelapse of the build. I fended off the task until one day I had no choice, I had to print something in PLA real quick, and the packed printer was the only one available.

Teaser for next project: Arduino-driven 8mm film scanner

I’ve been rather busy of late, so I haven’t had time to deliver the second part on the 3D scanner … More Teaser for next project: Arduino-driven 8mm film scanner

3D Scanning with Autodesk’s 123D Catch

I’ve been a little busy lately, what with the new curriculum at Haaga-Helia being introduced and whatnot, but I’ve also managed to do something I have wondered about for a while already. I found a piece of software, Autodesk’s 123D Catch, and it seems to work really well with my pet project, the 3D printed 3D scanner system. Now that the printing department of the 3D Lab works well, with the 3 Minifactories and one CoLiDo Printrite, it’s time to take the next step.

Greetings from Denmark

This blog entry comes from Copenhagen. Our university, Haaga-Helia, has for ten years been involved in an international IT seminar for students, and this year’s seminar is #9 in the series (2013 was such a messy year for all participating universities that we decided to skip it that year). The other schools are Cphbusiness in Copenhagen, Universidad Europea de Madrid from Spain, and a new entry this year, HES-SO from Switzerland.

The structure of the seminar is always the same, as is the theme, “How to be an IT professional”. The seminar runs for a week, with every school hosting a day. Usually there is a lecture in the morning, and then a workshop before lunch to be continued into the afternoon. Many times we have had social events and a business visit, for example last year in Helsinki we took the Spårakoff beer tram and went to Remedy Entertainment to see how games are made.

CeBIT Trade Fair 2015, Day 4 and closing notes


The weather kept up but there was a brisk breeze as we headed out to the Messe for the final visit. By now we had been to all the halls and seen all that was available, and the purpose of this day was to go and check out some things again.

I spent two hours checking the multitude of Chinese thingamajigs and whatchamacallits, most with Bluetooth if not gigabit LAN. It’s amazing what they have come up with, and were I in the market for importing USB connectors or cabling or selfie sticks, I’d have been in heaven. It was interesting as it was, don’t get me wrong. Like this Taiwanese window washing robot.

CeBIT Trade Fair 2015, Day 3

On Wednesday we hopped on the commuter train 8 again in the direction of Messe Nord. It’s very handy to have the hotel right by the railway station from which the trains leave for CeBIT and also for Hamburg tomorrow.

When I see men in lederhosen with traditional musical instruments, I can’t resist the urge to start this day’s blog with a video.

CeBIT Trade Fair 2015, Day 2

Another sunny day here in Hannover.

Sunny morning

We went to the fair around ten this morning, and I started from halls 1 and 2. Mostly filled with IBM and other very large companies, but it was interesting nevertheless. IBM was trying to get back into academic co-operation (apparently Microsoft has ousted them from the close relationship they had previously, so my business card was hot stuff).
