a Design of a 3D printed heatable cartridge used to enclose a conventional syringe containing a magnetorheological ink for DIW printers. Controlled increases in temperature improve the printability of the ink enhancing its polymerisation. b Temperature distribution measured after the application of 30V for 10 min, showing numerical and experimental results for two printing strategies. c Optimised solution provided by the in-silico platform in terms of local printing directions to provide a uniform distribution of temperatures. The inclination angle with respect to the printing bed is defined by αX, while the proper printing direction of each cartridge division (i) is defined by \({\alpha }_{Z}^{i}\). d Comparison of the temperature profile obtained experimentally and numerically from the optimised heatable cartridge. The average surface temperature is represented in the graph along with its standard deviation. e Comparison of the experimental printing resolution improvement when using the heating cartridge. f Printing of a magnetoactive gripper. This gripper closes when a magnetic field is applied.
