My 3D Printing diary

Recommended Posts

Great idea, and certainly very interesting, I have it already internalized.

but ... why did you have it not published here with us?

Something interested many on 3D printing, as well as me at the beginning:

- The known limitations of such a machine, some potential customers are initially was not clear.

- The expectations of such a machine are often much too high and maybe even utopian.

- A very fine resolution of the Z-axis robs above all a lot of time, unfortunately you will not get much more.

- 3D objects must be matched to the capabilities of the machine, then it can give pleasure. Other way around the 3D experience leads to large disappointments.

Nevertheless, everything related to 3D printing is stunning interesting. Especially as a private individual you can suddenly create small and big things. Useful or art things are suddenly within reach. A small individual factory for anything and anyone.

:-P I love it.

Good write up, however, 20 microns on a UM2 is pointless, and very different to 25 microns on a Form1

It's true that the Z axis on the UM2 can move in such small increments, but you'll never see the benefits of it in your prints, it'll just increase the print time beyond anything acceptable. I can see improvements from 40 microns to 60 microns, but even this adds many hours to a print.

Below 40 is not visibly better, you run into other factors such as nozzle size, ooze etc.

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
