ColorFabb ColorFabb Red varioShore TPU Filament - 1.75mm (0.70kg)
This revolutionary new material from Colorfabb allows users to vary the density of printed parts by adjusting temperature and material throughput - At temperatures between 200°C and 250°C the material will start to expand to roughly 1.4 - 1.6 times its original volume. When printed at low flow rates (60-70%) the active foaming properties will cause parts to expand, resulting in very soft printed parts. At temperatures between 190°C and 200°C the material can be printed without foaming, which results in harder prints when compared to those that utilized Varioshore's active foaming properties.
The base TPU is 92A, which will work with most standard extruder set-ups.

Printing soft parts, such as bike handlebars or shoe soles, couldn't be easier with varioShore TPU!
VARIOSHORE IS FLEXIBLE TO THE TOUCH AND FLEXIBLE IN ITS APPLICATION:
Although not quite as lightweight as LW-PLA, ColorFabb varioShore TPU provides users with noticeable weight and density reduction where it matters and the flexibility to use the material in a wide range of other applications. This material is well suited for producing soft sporting goods such as bicycle handlebars or for applications in footwear such as shoe insoles.
The base TPU is 92A, which will work with most standard extruder set-ups for Bowden and direct drive systems.
By adjusting material flow rates, ColorFabb varioShore enables users to significantly reduces the weight and density of printed parts.
HOW TO SUCCEED WHEN PRINTING WITH VARIOSHORE TPU
The following settings are recommended for successfully printing with this material:
Print Temperature:
- 190°-250°C
Print Speed:
- 20-30mm/s
Print Bed Temperature:
- 20°-40°C
Cooling Fan:
- Users are advised to use the least amount of cooling possible when maximum foaming is desired. For better overhang performance use 50-100% speed when cooling. Additionally, it is advised to make sure the distance between the nozzle and print surface is not too small, especially if the material is foaming while printing - pressure will need to be released from the hot end to prevent clogging and material feeding issues.
This material is not limited to one shore hardness - with the right print settings you can have multiple shore hardnesses in one print!

Questions
Does this material float when it is printed in the foaming \ low density settings?
Am I hungry
Hello, is this safe for food contact? Does it store well for long periods of time?
The max foam for this the shore hardness is a 65. Compared to a prop foam sword is it softer or harder?
A prop foam sword is an ambiguous standard for comparison.
At the Colorfabb website, they actually claim an even lower, Shore hardness rating of 55A for Varioshore at its minimum density. I have corroborated this with my own testing, achieving 55A with prints at 230 - 240 deg C. For me, going higher than 240 deg C causes over-extrusion and excess dimensions on the printed part vs. drawing specs, and changes to the granularity of the foaming — all of which increase the stiffness of the printed part.
So, how soft is 55A? If you’ve poked around with those white, silicone rubber erasers for mechanical pencils — those are right about at 55A.
How “thick” the object is and how much infill is used will have significant impacts on the perceived stiffness and hardness of the object that is made from this material.
