In a DIY project, YouTuber Jón Schone has developed a new type of 3D printer with a multi-tool function. This so-called “TIME system” (True Independent Multiple Extrusion) 3D printer has several independently operating tool heads that can move freely.
In contrast to conventional IDEX (Independent Dual Extrusion) systems, in which the extruders are only independent in one axis, Schone’s design enables all tools to be completely independent. This means that, in theory, completely different objects can be printed in parallel or an object can be produced with different tools and materials in a single pass.
“With this system, it is possible to print completely different parts in parallel or produce the same part using multiple tools,” explains Schone. “Even more interesting, however, is the possibility of combining completely different materials.”
As examples of applications, he mentions the application of adhesive between layers for reinforcement or the use of concrete as a filling material for weight adjustment. “There are many more applications that we will be exploring in future videos,” says Schone.
The mechanical basis is a modified plate with attached linear rails and two coreXZ gantries made from 3D-printed parts and carbon fiber rods. The complex structure is driven by a total of six motors and controlled by a Duet controller in conjunction with Revo-Roto toolboards from E3D.
Even though Schone had to overcome a few hurdles during construction and configuration, the prototype appears to be basically functional. He demonstrates the function in a test print, but also admits to quality problems due to synchronization errors.
