Hybrid Car Has Body 3D-Printed via Stratasys Technology

Stratasys has announced a development partnership with the Winnipeg, Canada, engineering group Kor Ecologic. The engineering group is creating a highly fuel-efficient and environmentally friendly motor vehicle, code-named Urbee, that is the first car ever to have its entire body 3D-printed via additive manufacturing processes.

In terms of US gallons, the electric/liquid-fuel hybrid vehicle offers fuel economy of better than 200 mpg on the highway and 100 mpg in city driving with either gasoline or ethanol. (Equivalents would be 85 km/l highway and 42.5 km/l city, or 1.18 l/100 km and 2.35 l/100 km city, respectively.)

The car is charged overnight from any standard home electrical outlet. Alternately, it can be charged by renewable energy from a windmill or a solar-panel array small enough to fit atop a single-car garage.

“Other hybrids on the road today were developed by applying ‘green’ standards to traditional vehicle formats,” says Jim Kor, president and chief technology officer of Kor Ecologic. “Urbee was designed with environmentally sustainable principles dictating every step of its design.”

Stratasys developed the fused deposition modelling (FDM) rapid prototyping process that was used to build the Urbee.

“Our goal in designing [the car] was to be as green as possible throughout the design and manufacturing processes. FDM technology from Stratasys has been central to meeting that objective. FDM lets us eliminate tooling, machining and handwork, and it brings incredible efficiency when a design change is needed. If you can get to a pilot run without any tooling, you have advantages.”

Urbee is the first prototype car ever to have its entire body 3D-printed by means of an additive process. All exterior components, including the glass-panel prototypes, were created using Dimension 3D Printers and Fortus 3D Production Systems at Stratasys’ RedEye on Demand digital manufacturing service.

A full-scale Urbee prototype was displayed for the first time in the United States at the SEMA Show in Las Vegas in early November by technology partner Tebis. A 1/6-scale finished model was shown at the Stratasys booth.

Some Plastic Molding Methods

Plastic is widely used by several different manufacturers because it can be printed easily. There are several common methods of plastic molding. Here are three commonly used plastic molding methods.

Blow Molding

This plastic molding method starts by melting molten plastic in the machine room and then sending the liquid plastic to the mold to make the desired shape. Blow molding specializes in creating Hallow products such as bottles, motorcycle fuel tanks, hoses, bumpers, and several other hollow products. In addition, the final product is smooth. The main process of this method is that air is blown and locked to create holes. When liquid plastic is poured into a mold, the plastic will harden so you can make the shape you want. Then, you can remove the mold through the mold cavity.

Plastic Mold

This type of method uses thermoplastics. Among other methods, this is more often used by manufacturers. Methods include firing thermoplastic hot liquids at high speed into ceramic molds. Then, the mold is tightly bound while the plastic will follow the shape of the mold. The plastic will be cooled by small vents on each side. When it is cold, it is removed and then painted. However, this method leaves fewer stitches so that the final product will be finished for better results. Products made through this method include toys, MP3 player boxes, car dashboard casings, and several others.


This method focuses on making larger items that are mainly used for industrial use and home furnishings. This method is quite simple. You only need to heat the plastic until it is soft so that it can be manipulated to create the desired shape. Then, the small machine will add any detail to things like body polishing, decoration, and also tracking the stamp. Common products from this method include aircraft windshields, truck beds, industrial pallets, and several other large items.

Plastic is one of the main materials for several manufacturers. Plastic manufacturing products have been widely used by most customers. Plastic products that are commonly used include car bumpers, cell phones, incubators for babies, and several other items for both household and industry. Each of these products might require a different method.
