BUTLER fabrication™

About BUTLER fabrication™ ?

REX-Series is a 3D printing system with a new concept that combines a robot and our large 3D print head, which has a proven track record with EXF-12.
It is possible to mold not only thermoplastic resin pellets, but also recycled materials, bioplastic materials, etc.
BUTLER fabrication™ requires less space to install than our large 3D additive manufacturing machine EXF-12, which uses collaborative robots, and targets small to medium-sized objects.
This is a popular version to further promote our mission "Green Creative™".

BUTLER fabrication™ isThe system consists of the following four elements.
1) Proprietary 3DP head    2) Commercially available collaborative robo
3) Dedicated control unit   4) Software

​We have a 3D print head developed in-house, a dedicated control unit, a dedicated slicer, and peripheral equipment.
​Can be used as BUTLER fabrication™ by combining with a commercially available collaborative robot*.

*As of November 2023, compatible with Universal Robot's UR16e, etc. We will gradually increase the number of compatible models.

Example of 3D printing with REX-Series

We will introduce molding samples etc.
​ *The sample is an example of printing using a BUTLER fabrication™ prototype machine.

Application to MMA (multi-tool) system

BUTLER fabrication™ can be expanded as an MMA system (Multi-Mode Additive Manufacturing System) by adding optional dedicated units (currently under development).This is a completely new system that can be used to expand various construction methods such as milling for finish cutting and injection molding using simple molds.

Features of MMA system

Example of MMA system configuration

Basic specifications of standard system

The specifications are based on the configuration of the standard head, dedicated unit, and UR16e.

​Specifications vary depending on the model of collaborative robot to be combined.
