Designing and 3D Printing a Functional Kamen Rider CRD Helmet

Today’s guest post is by Russ Ogi, Chief Operating Officer of Z Corp Partner, RAPID Technology LLC.

Developing the Concept
Born and raised in Hawaii, I had the benefit of seeing both Western and Eastern superheroes. I grew up with American superheroes like Spiderman, Batman and Superman, but I was also exposed to Japanese superheroes like Kikaida, Inazuman and Kamen Rider.

The latter fall into the genre of Tokusatsu, Japanese live-action shows that involve superheroes. This genre spawned an estimated 3 - 4 billion dollar global industry that eventually made its way into all corners of the globe from Asia to Europe and the Americas. In the United States, the original Japanese shows eventually got watered down (due to US TV standards) into what most in the States know today as the Power Rangers.

So, what does a superhero geek do when he grows up and you give him access to a prototyping studio and some of the most talented artists in the industry? He makes superhero armor.

The idea behind the Kamen Rider CRD helmet was to create a more contemporary version of the original Kamen Rider V3 character from the 70's. The goal was to create a 1:1 scale wearable helmet based on this concept.

I worked with Calvin Lac, an Application Engineer here at RAPID Technology, on the design for the helmet. Calvin is an award-winning model maker and artist.

We tried to take original elements from the character and give it an edgier, more mature feel using antiquing techniques to make newly printed Z Corp 3D printed parts appear old. Calvin, an avid Gundam fan, tried to incorporate Gundam design elements as well.

I have a deep appreciation of Swiss surrealist H.R. Giger's work and wanted a bio-mechanical feel to the overall design. Some areas were to have organic, fluid looking curves, while other areas would have hard edges and well-defined lines. Above all, unlike some remakes, I wanted it to preserve the spirit of the character and pay homage to the original show, keeping long-time fans happy and hopefully winning some new ones.


Designing the Helmet in 3D CAD
Once we had the idea hammered out, we began designing in 3D with the CAD program Maya. At this stage, the helmet went through several changes and then was engineered for 3D printing.

3D Printing the Helmet
The 3D model was printed on the ZPrinter 450 in parts. We created the lower jaw separately to allow the helmet to be worn and retain a tight fit on the wearer's head. We finished the 3D printed helmet prototype with ZMax to provide extra strength to the helmet so it could be used as a true functional part in production work. Finally, we assembled the helmet and prepared the surface for gloss painting.

Painting the 3D Printed Helmet
We kept to the original color scheme of the character as much as possible. The original Kamen Rider V3 had a grey lower jaw. We opted for silver because we thought it would match the mechanical aspect of our design better. We also selected darker colors to give the character a more mature and contemporary feel. The helmet was painted in layers and sections.

Casting the Resin Eyes
The Rider eyes were cast in resin. The masters were 3D printed and silicone molds were made. Then we mounted the resin eyes in the helmet.

Adding Lights and Antenna
We added lights in the back of the eyes in order to give them a glowing effect. Finally the antennae were added to complete the look. Some of the smaller details were created in Z Corp’s ZBuilder Ultra plastic prototyping system and then painted.

Next on the list, creating the entire suit?

  2. @ Excell - Thank you.

    @ Mohd Fahmi - We primarily follow traditional casting techniques similar to the ones that can be found on YouTube.

    Have you found those videos? If so, was there something specific to your project that was not covered?

    Casting always takes a bit of practice and experience as the different shapes or details of the part being cast affects the exact process. More of an art than science.

    Hope this helps.

  3. Two questions.
    1. How hard is it to learn how to use the 3d CAD?
    2. Would it be possible for an average person to have access to one of those machines?
