Update from our intern

Team colorFabb

A few weeks ago we introduced our new intern, Niels van Valburg. You can read the previous post here.

Below is the progress on his project he is working on at colorFabb:

 

Hey there!

So last time I explained a bit about what my project is going to be about. For those of you who have not yet read the previous post, I am doing my Bachelor Thesis project for Industrial Product Design at colorFabb. The idea is to print a chair with nGen_FLEX where the material properties are used to an advantage.

So to give an update on how it is going so far. I started researching how I could use metamaterials to make functional parts without having to assemble them. Metamaterials are materials that are engineered in such a way, that they have properties that they normally would not have. A good example are the colorFabb Pliers!

So I have experimented with different designs, and came up with a solution on how to apply it in my concept so far. In the sketches you can see the result.

Some of the test prints made during this study:

So now the real engineering and printing can begin. I still have to figure out how to connect all the parts of the chair together, but I already have some ideas on how it might work.

So until next time!

Niels is doing a lot of research with nGen_FLEX.

About nGen-FLEX

nGen_FLEX was developed with Eastman chemical company. Based on their work with co-polyesters nGen_FLEX makes a very compatible material with other Amphora grade materials.

With just the right amount of flex, nGen_FLEX is best described as a semi flexible material. Still capable of being fed through a Bowden tube and printed at regular PLA speeds.

Fast printing
nGen_FLEX is engineered as a semi-flexible materials which allows most users to print at regular print speeds, cutting down build times compared to other very flexible filaments. Also bowden style 3D printers, 1.75mm and 2.85mm, will be able to push this filament through without much trouble.

Temperature resistance
nGen_FLEX is temperature resistant to about 125C. That means 3D printed objects can be steam sterilized at 121C.

Flexible and tough
Printed in single perimeters and without infill or very little objects will feel quite flexible, but printed with multiple perimeters and more infill objects will be very firm and tough. The material is rated at a shore hardness of 95A.
