MegaHouse Boosts Design & Development Efficiency with Eden260
Tokyo-based MegaHouse develops and manufactures high-precision figures and toy foods targeted to both adults and children. Because the company serves a wide range of customers and its products often comprise many finely detailed parts and usually have short life cycles, MegaHouse works hard to streamline development.

To reduce costs and speed time to market, MegaHouse has focused on improving the efficiency of its design process. It installed 3-D CAD tools and attempted to cut development costs by enhancing its die fabrication process. MegaHouse subcontracted prototyping and created just one prototype for each product. Consequently, preliminary examination according to prototyping was insufficient and design defects were often found after the die was fabricated. The post-process design changes, die modifications and other steps needed to correct the problems extended development time and added extra costs – just the opposite of what MegaHouse needed.

Ease of use and high precision makes Eden260™ a winner
MegaHouse considered its rapid prototyping options and decided that installing an RP system onsite was the best way to reduce prototyping costs, increase access to prototypes, improve design quality and reduce development time.

It selected Objet’s Eden260™ because the 3-dimensional printing system enabled molding with a high level of precision, supporting their need to verify mechanisms, and because it was easy to use, enabling MegaHouse to create molds with non-expert staff. The strength of Objet’s FullCure® materials was another advantage of the Eden260™ as it allowed MegaHouse designers to test the models without fear of damaging them.

Benefits exceed expectations
The Eden260™ proved its value within a very short time, bringing benefits that went far beyond what MegaHouse had expected.

The Eden260™ makes it possible to easily obtain a high-precision prototype in the early stages of conceptual design. This means that design work can now proceed without the delays MegaHouse used to incur while waiting for the service bureau, thus considerably reducing design time. Also, the Eden260™ enables design defects to be found before the die is fabricated, avoiding the post-processing changes that had previously cost MegaHouse so much time and expense. The ability to handle virtually all prototyping in-house has created significant cost savings for MegaHouse.

Also, due to the weakness of the material used for the prototypes that were subcontracted, the strength could not be verified until a molded product made with the die was available. Now, with the Eden260™-produced models, product strength and parts fit can be verified during development.

Because it is so easy and cost effective to make models using the Eden260™, the models can be repeatedly and even somewhat roughly handled. This allows everyone in the design and development team to examine and “play” with them, improving understanding and enabling more effective product verification and quality assurance. This has been particularly noticeable when verifying the constitutional parts.

Even the sales department has benefited from the installation of the Eden260™, as presentation models are now used in sales activities right from the early stages – an important competitive advantage for MegaHouse.
