Dual Extruder 3D printer

Dual Extruder 3D printer

Dual Extruder 3D printing allows for the user to combine colours and materials onto a single 3D print platform. With the Hydra 21 you have the option of dual extruders. Actually up to an amazing number of ten extruders! In fact the printer combines a variety of printheads or tools on one platform. Printers like this are also called Hybrid, Multi-tool or Multifunctional 3D printers. It is as simple as that really! Well, no not really! Typically, 3D printers come with one type of printhead or laser fixed in place.

So, one of the main considerations for organisations considering which 3D printer to invest in, requires matching an application with the best 3D printer technology for that application. This can be very restrictive and application limiting. Not what you want!

One System, Infinite Possibilities

Dual Extruder 3D printing with an All in one 3D printer or (AIO) you get the best of all technologies. This means your organisation will benefit from the flexibility of a range of functionalities; 3D printing with syringes, nozzles, printheads and extruders. With further options of UV light, CNC milling, laser cutting, engraving. There is even an option for microscope and ‘pick and place’ capabilities.

It is now unnecessary to invest in different 3D printers. AIO will not only be saving space. Most importantly you get loads of application and material flexibility.

Application use as an example

The field of soft robotics is seeing rapid development. Here, materials are central to performance and functionality. This application requires composite structures that combine. Elastomers capable of large elastic deformations with stiffening components. These are used to restrict body strains in movement and to house electronic within.

As a result soft robot performance is highly sensitive to material composition, material distributions, and component geometries. E.g., flexural rigidity distributions on bodies, fingers, tentacles, wings, fins, etc. Historical processes like casting restrict designs with advanced geometries and material options. Additionally, these processes have complicated manufacturing steps that increase delivery time.

Instead, 3D printing provides real advantages in the processing of multiple materials in composite structures. Therefore a Dual extruder in an combines a variety of printheads or tools on one platform becoming the ‘go to’ process for working robots.

In particular, embedded 3D printing (E3DP) is of interest for its compatibility with multi-material fabrication.

Material inks extruded into a fluid reservoir (matrix) and used as a sacrificial support material during printing is a perfect process for fabricating soft sensors, fluid-based actuation for soft robots, and perfusable tubular structures.

The use of the Dual extruder capability in an All in one 3D printer or (AIO) which provides a multi-purpose 3-axis motion control and can accommodate a series of deposition tools simplifies the process for the fabrication of soft robotics. Here, Fused filament fusion is used to produce moulds and fluid dispensing via a pneumatic fluid dispensing system (Ultimus V, Nordson EFD) with actuated disposable Luer-tipped syringes all in one system.
