Doosan selected the Object Eden500V due to its ease of use and speed.
Doosan Infracore is a global leader in the production of heavy duty, best-of-breed
excavation equipment. Until recently, the company created prototype models using
CNC and silicon molds, or it would outsource its concept modeling to a service
provider. Outsourcing was slow, however, and the resulting models were not printed in
fine enough detail.
Doosan Infracore installed the Objet® Eden500V™ 3D Printer in-house at its design
headquarters because of the printer’s ease of use and speed. Doosan Infracore saw
immediate benefits from the printer’s ability to produce fully cured concept models more
quickly – no matter how complex the design. The result radically decreased production
costs and times, and increased creativity.
"Concept modeling before we had the Objet Eden500V 3D Printer was a lengthy and
wasteful process," says Yoonkwan Park, senior designer. "After design, the project went
to manufacturing, and then it took a few months until the complete concept model was
ready. This was expensive, and I was always concerned about exposing our cuttingedge
designs to a third party."
"The Objet Eden500V is the perfect solution for preparing concept models in our
industry," says Park. "It is useful for a multitude of applications such as dyeing and
chrome coating. It is also good at silicon molding because of its fine surface detailing.
This further increases its value."
Park also praises the Eden 3D Printer for its ability to provide fine detail and deliver
quality post-processing, qualities that other rapid prototyping machines lack.
Doosan built a model for the Red Dot Competition that won a Red Dot Best of the Best award.
Doosan Infracore integrated the 3D printer into its production processes and uses this
machine to print concept models and cure parts.
Recently, Doosan Infracore won a commendation in one of the world’s most prestigious
design competitions. The 2009 Red Dot Competition attracted more than 2,733 entries,
of which only 15 received a "best of the best" commendation. Doosan Infracore’s awardwinning
model, built on the Objet Eden 3D Printer, was the CX Eco Transformer, an
innovative excavator scheduled for release in 2018. The CX Eco Transformer was chosen
by Red Dot for its ecological soundness, safety, usability and efficiency.
In order to take part in the Red Dot Design Award, Doosan Infracore prepared a concept
model using the Objet Eden500V Printer and Rigid Opaque material. This robust material
offers a wide range of mechanical properties, including the ability to withstand bending. It
has good impact strength and high contrast between the model and support materials. In
addition, the surfaces enhance visualization of details and edges.
The company had only a very short lead time, and Park says that without the Eden 3D
Printer, "I do not think we could have met the lead time on this project. Our processes are
so much faster and simpler now."
