  We have made an attempt to reproduce 17 objects of the IMAGINARY Open
Mathematics Exhibition (www.imaginary.org) using low-cost, desktop 3D printers.
The IMAGINARY open math is an international project by the Mathematisches
Forschungsinstitut Oberwolfach in Germany and includes galleries of volumetric
objects that are unique, have aesthetic appeal and mathematical meaning. We
illustrate here the printing of these diverse learning materials using new 3D
affordable printing technologies based on Fused Deposition Modelling (FDM) and
the use of biodegradable plastic PLA. The final goal is to support museums,
schools and higher education institutions in countries with lower scientific
infrastructure.
