Multi-material printing - for 3D printed components with even greater durability


What is 2-component 3D printing?

Two-component parts combine the advantages of two different materials in a single part. The two can be two different filaments, a combination of 3D printing and injection moulding, or the combination of different materials such as plastic and metal.
 
igus® tribo-filaments have unique, outstanding wear resistance and coefficient of friction. But there are also other 3D printing materials that have been specially optimised for a high degree of strength and rigidity. With multi-material printing, tribo-filaments can be combined with other materials within a component in order to supplement the high degree of wear-resistance with further mechanical and functional properties.  
 
Do you have an application that requires the use of multi-material components? We will be happy to help you with the implementation of your project.

What kinds of multi-material combinations are there?

How and with what materials can iglidur® tribo-filaments be combined?

Many materials are compatible and can be combined in one way or another in two-component printing. Similar filaments (such a materials with the same base polymer or similar processing temperatures) can be firmly bonded: the materials meld with one another, connecting the component's two "phases". This no longer functions when the difference between processing temperatures is too great: then one of the two materials may not remain dimensionally stable during processing or may even be subjected to damaging temperatures. To be absolutely certain of the connection, an interlocking design in which the two phases are combined so that they cannot be separated by non-destructive means is a good option.

Mechanical properties

Two-component additive manufacture

Tribo-filaments are combined with highly rigid or flexible materials. This enables the construction of very strong components - including ones made with the lightweight construction method - in combination with the tribological advantages of iglidur filaments. The combination of iglidur filaments with flexible materials is highly suitable for the manufacture of gripper fingers, if the gripping surface has to provide a good grip but the moving components have to slide.  

Injection moulding combined with 3D printing

Roller from injection moulding and 3D printing

Moulded 3D printed components, make it possible to implement geometries that are only possible with 3D printing in combination with the larger choice of available materials in the area of injection moulding, as all iglidur materials can be selected.

3D printing with smart functions

3D printing with sensors

Multi-material printing enables the speedy manufacture of wear-resistant polymers with an integrated sensor layer. This is how extremely durable special parts are created which issue a warning before overloading occurs or when the wear limit is reached to enable predictive maintenance.  


Where are two-component parts used?

Bell crank

3D printed bell crank

A component for deflecting forces; its great rigidity protects the joint from interfering influences. The bearing points are very smooth-running, durable, and wear-resistant. A good solution here is a combination of a carbon-fibre-reinforced filament such as igumid P150 and a tribologically optimised material such as one of the iglidur tribofilaments from igus.

Gripper

3D-printed gripper

The dynamic requirements dictate that the gripper element be as light as possible, but with great flexural strength, and grip securely but gently. While the gripper's body is manufactured with a fibre-reinforced filament, a flexible filament whose high coefficient of friction ensures a secure grip can be used for the gripping surfaces. 

Lead screw support block

A shaft's bearings should compensate for any angle errors and dampen shocks. The iglidur® plain bearing element can be encased with a flexible filament such as TPU with a Shore hardness of 95 A.


Why 3D printing from igus?

With five decades of expertise in wear-resistant components made of self-lubricating high-performance plastics, igus® brings new capabilities to 3D printing. We offer solutions developed especially for moving applications, in which usual materials would quickly reach their limits – our plastics exhibit wear resistance of up to 50 times that of standard 3D printing plastics.
 
iglidur® polymers and the products they are used to make are tested extensively for wear, friction, and durability in our in-house test laboratory . The abrasion resistance of 3D printed components has been proven and documented in many tests: this video shows a wear test on a sliding element of I180 tribo-filament compared to a 3D printed part of standard ABS 3D printing material.


print2mold: fast and cost-effective injection moulded parts

For two-component printing and more: print2mold, the igus® Rapid Tooling method, allows wear-resistant components from additive manufacturing quickly and easily from iglidur® injection moulding plastics. Just upload the 3D model to the igus® 3D printing service, select the material and quantity you want, and calculate the price. After a quick check and confirmation by our engineers, your parts will be prepared for shipment within less than ten days' time and delivered.
