And suddenly he has an ear….


The latest object I made with a 3D pen was tittled ‘Don’t loose your head’. One more addition in finishing this artwork was adding an ear. For now it is the largest object I made with a 3d PEN so far. I have put in beside the last one on one photo and I see the ew object is more then 40 cm high.

So, an object fit for an exhibition one of these days. Will let you know when that happens. I have discoverd nos a technique that works quite well with this specific 3D pen from Myriwell, and the ABS plastic (filiament) becomes strong enough to form larger objects that can be touched without breaking.

So drawing with a 3D pen and making a 3D object with it has become reality. You only need a lot of practice and patience. The object you see here took two days of work, and about 8 hours working time. You can’t concentrate the whole time, so you need a break now and then. But as you see, you can make it work, and the forms are what you want them to be.

Beside the larger object you also see the previous one and some of the IUOMA logo’s I created.

“The Eye Catcher’s Friend” – 3D work by Ruud Janssen

2016-07-09 18.25.42

“The Eye Catcher” was the name of the object I made last week with a MiRywell 3D pen.  I used several colours of ABS plastics to make it. Today I made “The Eyecatcher’s Friend”, another object made with the 3D pen, this time black, grey, white, brown, gold and Beige PLA plastics. The connection is there since the first object has the nodes to detect, and the other object is sending all these signals.

Will try to make a few better photos when there is sunlight.


The New LIX pen arrived

After waiting for 2 years for the LIX pen, today (May 21st 2016) it finally arrived. Just Like Spring arrived….. The LIX pen is a Kickstarter project where a firm designed a new 3D pen and after some troubles finally managed to produce it and started distributing the pen. I must say, it looks good, and it promisses to be a great tool.  Soon I will be able to test it and show you the results. Also, when there are problems, I will tell you how it is. I have been working a lot with 3D pens, so will be able to compare. Here are some photos of the unpacking of the LIX pen…..

New pens

2016-03-06 09.29.40

Just bought a set of new pens, Rotring 2000 isograph, with several types of nibs. It means I can work faster with indian ink and have more control on the broadness of the lines I use in my work.  I normaly use the traditional nibs, since that works the best, but for design, these pens are very good indeed.  Teset days I worked on cleaning them and testing them. One of the papers used for that (see below) I lateron used as writing paper for a letter to De Villo Sloan in USA…….

On my new drawings you will see the results since they are used now in the new drawings I make on a weekly basis.
