3D Printing - Functional Prototyping Solutions - Living Hinges 

A living hinge is a thin flexible flap made from the same material as the two rigid pieces it connects, rather than cloth leather or some other flexible substance. It is typically thinned or cut to allow the rigid pieces to bend along the line of the hinge. PolyJet 3D Printing materials, including Rubber–like Digital Materials, have excellent elongation–to–break characteristics and superior tear resistance that can be used for flexible hinges that can be used over and over without breaking. You can now create long–lasting, functional prototypes of products with thin flexible hinge (flexure bearing) made from plastic that joins two rigid parts.


How it Works

When you are building a prototype and you want it to mimic how the real product will actually function, you need to consider how it moves. The living hinges that hold the joints together will allow prototypes the movement they need to function according to the CAD design.
Due to outstanding elongation-to-break and extremely good tear resistance of the materials, Connex Printing systems makes it possible. You can rest assured that your prototype will be able to withstand repeated bending.

The Polyjet 3D Printed Living Hinges 

When 3D printed a living hinge is a thin flexible hinge (flexure bearing) made from plastic, as opposed to cloth, leather, or some other substance, that joins two rigid plastic parts. The hinge allows the plastic parts to bend along the line of the hinge. It is typically manufactured in an injection molding process that creates all three parts at one time as a single entity. A thinned section of the plastic part bends to allow movement. The hinge's minimal friction and little wear make it useful in the design of micro electromechanical systems. If correctly designed and manufactured, living hinges remain functional during the entire life of the product as these hinges can flex more than a million cycles without failure. Polyethylene and polypropylene are considered to be the best resins for living hinges due to their excellent fatigue resistance. The low cost and ease of manufacturing makes them quite common in disposable packaging.

 

The Technology used for creating Living Hinges 

Fused Deposition Modeling (FDM) Technology 

Using FDM technology allows affordability and durability by printing concept models with production-grade thermoplastics. 
FDM 3D Printers are office friendly and they produce small models in hours and large models in days. The FDM printed models can be drilled, sanded and painted according to your preference to create a perfect finishing of your prototype. 

     

PolyJet 3D Printing Technology

As a 3D printing process, this technology produces amazingly realistic models. The printing technology builds accurate models by incorporating multiple materials into one automated part to create prototypes that look and feel like finished products. With fine details, smooth surfaces, rigid housings, soft-touch buttons, lettering, rubberlike seals and even clear components, your models can look the part at a trade show, a presentation or even during a sales pitch.
