London designer makes use of 3D printing to supply air-filtering bicycle wheel

Kristen Tapping, an industrial design graduate from London South Bank University, is utilizing 3D printing to supply a bicycle wheel able to purifying air of pollution.

The novel invention is named Rolloe Roll Off Emissions, and makes use of a sequence of sponges and filters to entice dangerous emissions earlier than releasing clear air again into the atmosphere. Tapping claims the concept was impressed by the notoriously polluted streets of London – the Large Smoke – and believes the Rolloe will present a brand new methodology of fresh commuting for the bustling bicycle owner neighborhood.

City air air pollution

The air air pollution generally discovered in lots of main cities is basically human inflicted, and has turn out to be a subject of significant concern in recent times. Not solely is it linked with respiratory issues and shorter life spans, air air pollution additionally has main implications for international warming and the following results on delicately balanced ecosystems.

To fight this, many people have adopted cleaner strategies of every day transport equivalent to electrical automobiles and bicycles. The bikes particularly are nice for health-conscious people as they’ll additionally present the beneficial degree of every day cardio just by using to work and again.

In line with the European Cyclists’ Federation, the typical bike is liable for emitting simply 21g of CO2 for each kilometer traveled. This consists of 5g for the manufacturing course of and upkeep, and 16g for the energy burned by the biker peddling. Trying on the identical determine for a motorized vehicle: 271g of CO2 per passenger per kilometer, or 13x the emissions.

Rolloe Roll Off Emissions

The Rolloe wheel measures 600 x 600 x 60mm, and weighs about 1050g in whole. Designed to suit on the entrance of a typical bike body, it includes two rims with fins fabricated from ABS, and a central tri-wheel fabricated from nylon – all of which might both be 3D printed or injection molded. The meeting works by funneling air by way of the inside cylindrical opening of the rim the place three several types of filters are housed, earlier than expelling the purified air through the outside fins. It does this at a charge of 0.665m³ per kilometer.

The primary filter, an eco-friendly loofa sponge, traps massive particles and is washable for reuse. Subsequent, the HEPA filter (additionally washable) traps pollen and a few bigger particles equivalent to tyre and brake mud. The ultimate hurdle is the activated carbon filter, which is able to trapping particular person gasoline molecules. This makes it nice for filtering out risky natural compounds (VOCs) and even odors. Because it stands, the present prototype of the Rolloe requires these filters to be modified as soon as every week, or each 250km, to keep up its efficacy.

With the design finalized, Tapping ultimately intends to carry the product to market and predicts {that a} 10% market penetration in London alone might filter about 266,865m³ of air in a given day. The designer would additionally prefer to develop a rear wheel counterpart to double this quantity, one that may be 3D printed in weatherproof and sustainable supplies.

The 3D printing of bicycle parts is not any new enterprise, and has resulted in an a variety of benefits for each producers and shoppers. Simply final month, engineering agency Sandvik collaborated with e-bike design consultancy GSD World to 3D print titanium motor nodes for e-bikes. GSD, working with a number of bike OEMs, has discovered titanium elements equivalent to motor nodes, which anchor the electrical motor to the bike body, may be tough and expensive to fabricate utilizing conventional CNC strategies. With an altered DfAM-centric design, nevertheless, these manufacturing prices may be halved.

Elsewhere, composite 3D printing specialist AREVO just lately partnered with California-based Superstrata to 3D print the fully-unified carbon composite frames for its e-bikes. Utilizing Arevo’s steady carbon fiber 3D printing know-how, Superstrata was capable of get rid of the necessity for glues or welding to carry its particular person parts collectively whereas additionally producing a light-weight, sturdy body.
