I wonder if ultimaker 2 can print the stretchy Bracelet?

Recommended Posts

Hi, Robert, thank you for reply~

But I can not access Youtube, do you have any pictures for that?

Recently, I am trying to print this bracelet with a ultimaker original machine, but it seems it doesn't work well~~

Is it because the cura setting parameter is not right? Can you pls tell me the recommended parameter settings for cura?

i actually quite liked how they used the ultimaker during the maker faire to print the stretchy bracelet and to auto push off the bed. Because the bracelet has springiness in it, it actually gets sprung off the bed, giving much fun to the kids trying to catch it.

I am now imagining using this um vending wall, starting the print say 1 minute apart. So every one minute, you'll have a bracelet springing out of the wall of machines. It would be great fun to watch!

Well it's designed to be printed on blue tape and you need to clean the blue tape first with isopropyl alcohol. The blue tape comes with the UM2 but you will have to re-level

Having said that you could experiment with other surfaces. Here are some notes. You don't want it *too* sticky:


I would love a copy of the official "looping forever - push off with fan duct" version as I will be showing off a UM original and a UM 2 at a science expo in a few months and want to print bracelets continuously during the expo.

It's in the painting section. Painters use it especially on corners and edges to keep paint off of something.

The blue tape is what most people use. Green (frog tape) works okay also I have heard. I also hear white masking tape works but that has a different kind of glue that might be more difficult to clean off the glass.

Get as wide as you can. I use 75mm wide. Illuminarti found some 150mm wide!

Wide is good for 2 reasons:

1) If lifting on a tiny surface, you want as wide as possible tape as possible to hold down. Skinny tape lifts too easily.

2) It takes less time to apply the tape carefully (getting the edge of one tape perfect with the edge of the next tape).

MOST IMPORTANT, clean the blue tape with isopropyl alcohol before printing on it. This removes waxy surface. This alcohol can be found wherever bandages are sold:

isopropyl alcohol (bottom shelf)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
