Craftbot 3, Independent dual extrusion 3D Printer

This has been a while in the making but we are pleased to start taking orders. Following the success of the CB+, CB2 and XL the team have pulled out the stops  with the Craftbot 3 and made a machine to rival some of the more established names in the IDEX world. The Craftbot 3, is a steel framed and properly engineered 3D printer for sure. We had the pleasure of training on its maintenance and repair in Hungary during April 2018 and can honestly say this is the IDEX to buy. Now taking preorders with delivery in 4-6 weeks.

Description

The Supervisor

This highly hyped name stems from the fact that the CB3 has some inbuilt monitoring systems. The hype though is real and we can definitely see this machine matching and beating the other IDEX systems.

During the second week of April 2018, we were invited to Budapest, Hungary, to train on the repair and use of the CB3. It was during this time that we saw how well the machine was designed and built

Based on the typical Craftbot steel frame, the team have taken on board good practice in kinematic element design to ensure that the 3 axes are perpendicular.

The hotends are totally redesigned, integrating a titanium heatbreak, a very sturdy antirotation feature and convenient connectors everywhere to make maintenance a joy.

As you may already know, titanium has very poor thermal conductivity making it the ideal material for a heatbreak of a hotend capable of 300 °C.

As with all new Craftbots, the units ship with the latest stepper motor drivers by Trinamics, making printing as silent as possible.

The Z axis is now driven by a rolled ballscrew with light preload

The team have also improved the Wifi capability of the machine allowing for faster transfer of GCode. It can also send you an email if it detects printing issues.

Failure detection from clogging or grinding is done with the assistance of two encoder wheels that measure how much filament has passed through. this is compared to the the length of filament called for by the GCodes and if there is a discrepancy, recovery measures are triggered.

Alignment of the hotends is done using the typical vernier type scale in the X and Y direction while in the Z direction the height is adjusted mechanically. The latter allowing ditto and mirror printing with minimum effort.

One of the best aspects of working with CraftUnique, apart from the team being really nice people, is that they listen to their customers. That is why, in the new CB3 the build plate has been beefed up, a status LED has been placed behind the logo and improved WIFI capability.

Another cool point is that the hotends take M6x1 threaded nozzles making the CB3 commpatible with the Olsson Ruby and other similar speciality nozzles.
