Because of granule-based plastic processes, it’s now imaginable to design extremely sturdy merchandise and convey them economically, even in closed subject matter cycles.

Fraunhofer IWU demonstrates with its extremely versatile rack and car body how particular person configurability, low subject matter prices and excessive load-bearing capability can upload as much as extremely helpful merchandise. This era shall be on show at Formnext, which shall be held from 7 to 11 november 2023, at Fraunhofer’s joint stand Corridor 11 Stand D31.

3-D published plastic cabinets for battery electrical police automobiles: maximizing sporting capability

Battery-powered electrical automobiles considerably cut back carbon dioxide2 Emissions within the shipping sector Alternatively, the extra weight of high-voltage garage programs comes on the expense of the permissible payload until light-weight answers are discovered somewhere else. Fraunhofer IWU and MOSOLF Particular Automobiles GmbH suggest a suave way to concurrently cut back weight whilst optimizing shipment area: a 3-D-printed rear rack. The usage of the Mercedes Vito for instance, the rack and its fittings can save 26.5 kg in comparison to the former retrofit resolution.

The weight capability of the rack gadget stays utterly unchanged. The ground drawer of the brand new rack can toughen as much as 100 kg. Gadget sturdiness and versatility are essential necessities as apparatus for police use turns into increasingly more heavy. Ballistic armor, as an example, provides important weight. Alternatively, the brand new rack will have to supply versatile transportation for site visitors regulate, patrol tasks, or transporting police staff in large-scale operations.

The newly advanced rack suits seamlessly into the car’s external, requiring no further reinforcements or equipment, thus optimizing the baggage area on the rear. New overhead compartments supply extra cupboard space, due to an 8% expanded cupboard space. In fact, the rack is as secure as the usual retrofit model.

DynaLight: 3-D published plastic body for shipment motorcycles

Electrically powered shipment motorcycles will play a the most important function in emissions-free short-distance transportation someday. Saving car weight method extra payload capability. Alternatively, protection must no longer be suffering from advanced weight. Innvelo Shipment-Scooter designers from the Chemnitz Analysis Institute ICM have debuted a metal body. The companions within the DynaLight challenge are actually proposing a strong plastic resolution – published the usage of spiral extension additive production (SEAM) era just like the rear rack of a battery-powered electrical truck. The brand new plastic body saves about 10% in weight and prices.

Naturally, it is only as sensible because the previous one: supply products and services can shipping a field of beverages or a thermal field at the conveyor, with a complete payload capability of about 200 kilograms, together with the passenger. Companions within the DynaLight challenge come with Fraunhofer IWU, the Chemnitz Institute for eV Gadget and Plant Development (ICM), and Sauer Creations.

SEAM Cycle: Speedy, granule-based, recyclable 3-D printing

SEAM era used to be used to fabricate the rack and body. This 3-D printing procedure opens up new manufacturing and production probabilities on an business scale, because it permits huge manufacturing volumes at aggressive prices in a short while. The SEAM procedure advanced at Fraunhofer IWU is simplest 8 instances sooner than conventional 3-D printing. It adopts cost-effective same old plastic granules processing. This manner, in comparison to classical fused layer modeling (FLM) processes that use dear filament, manufacturing prices are as much as 200 instances decrease.

SEAM additionally contributes to the round financial system way, as it could possibly use granules got from recycled thermoplastics with out decreasing the price of the plastic from the former product. Plastic bottles too can develop into extremely versatile racks or service frames for e-scooters in 2d lifestyles.
