the primary 3D printed enduro e-bike prototype


Keep updated with every part that’s taking place within the great world of AM by way of our LinkedIn group.

Thok, a well known Italian model within the e-bike trade, has revealed its newest creation, the Thok P4. This groundbreaking prototype marks the first-ever enduro e-bike with a totally 3D-printed body.

Established in 2017 by former skilled biker and present CEO Stefano Migliorini, the corporate is headquartered within the Piedmont area. Thok as soon as once more showcases its pioneering spirit within the realm of enduro bikes with the introduction of the Thok P4. This distinctive e-bike prototype incorporates a fully useful 3D printed body, a collaborative achievement with famend service supplier Materialise. The revolutionary printing approach employed is Selective Laser Melting (SLM), which works past standard polymers to print composite fibers and metals just like the aluminum alloy (AlSi10Mg) used within the Thok P4.

Constructed from this aluminum alloy, the Thok P4 delivers flawless efficiency. It’s at the moment being utilized to finalize the event of Thok’s upcoming “gentle” e-bike, a pedal-assist mannequin designed to carefully emulate the conduct and dealing with of conventional pedal-powered bicycles.

In accordance with the corporate, the appliance of 3D printing know-how has yielded substantial benefits. Not like the previous, which required the creation of a minimum of three body prototypes earlier than reaching a useful one, 3D printing permits the rapid use of the primary mannequin. This not solely considerably reduces improvement timelines but in addition permits the conclusion of advanced geometries that have been beforehand unattainable utilizing conventional manufacturing strategies.

Whereas the long run trajectory of 3D printing is but to be totally outlined, the collaborative experimentation undertaken by THOK and Materialise holds a pivotal position on this narrative, driving innovation that can profit the worldwide e-bike trade as an entire.

Known as the THOK Undertaking 4 (with “P4” as a short lived identifier till the bicycle assumes its remaining kind and title), this prototype serves because the precursor to THOK’s anticipated “gentle e-MTB” crafted from carbon fiber. Anticipated to debut round 2024, this e-MTB will characteristic a Bosch SX motor and a battery providing completely different capacities (400 / 545 / 725 Wh) together with a variety extender.

Though the event course of is ongoing and sure technical elements stay topic to analysis (comparable to battery integration, configuration, and geometrical preferences), the 3D-printed prototype body is already present process rigorous testing on the technical trails of Finale Ligure and the Alba area.

The first goal of speedy prototyping utilizing 3D printing is to generate totally useful fashions able to testing numerous parameters, together with geometry, suspension, and part integration. The SLM know-how facilitates the creation of sufficiently light-weight elements for simulating desired materials properties, such because the traits of carbon fiber on this occasion.

Luca Burzio, the commercial designer at THOK overseeing the engineering elements of the initiatives, emphasised the constraints of conventional strategies in reaching a totally useful prototype with an built-in battery and motor. Conventional manufacturing processes usually contain elements created for hydroforming and necessitate molds, rendering sure elements tough to prototype conventionally. The 3D printed totally suspended e-bike developed by THOK addresses these challenges.

CEO Stefano Migliorini echoed this sentiment, contrasting the previous apply of a number of prototype iterations earlier than reaching a useful mannequin with the extra environment friendly method of the THOK P4. The primary prototype revision now carefully aligns with the thickness and dimensions typical of carbon fiber, offering a near-final driving expertise.

This endeavor introduced THOK and Materialise with novel challenges, serving as an academic platform for each entities. The collaboration expanded their experience within the bicycle sector, particularly regarding steel 3D printing, and enhanced their capability to satisfy the precise necessities of the Italian model.

As highlighted in quite a few articles over latest years, 3D printing’s position within the bicycle and e-bike area is gaining prominence, not solely in improvement but in addition within the manufacturing of ultimate elements. The collaborative experimentation between THOK and Materialise provides a major chapter to this evolving narrative, fostering innovation that can positively influence the worldwide e-bike trade.
