The Tanaruz 3D printed boat project by RAW Idea is starting to take shape. We have to admit that we were very skeptical about this project, which promises a bespoke fully 3D printed yacht available to everyone on demand (at a fair price). And there is still a long way to go to a real, tested and fully compliant product. But the project is moving forward and looks more and more interesting, although still far from commercial reality.
The Netherlands-based company seeks to create a more sustainable, efficient and innovative future for the shipbuilding industry. Raw idea plans to 3D print its custom boats from recycled polypropylene polymers, using pre-industrial waste. Specifically, they are made of recycled polypropylene (PP) with 30% fiberglass. This combination of materials has excellent mechanical properties such as an elongational strain of up to 5%, and is highly resistant to chemicals, heat and fire. The use of recyclable PP underlines Tanaruz’s commitment to circular economic principles.
Like a pair of 3D printed glasses, headphones or orthopedic insoles, Tanaruz boats are fully customizable via a mobile application for iOS and Android. Users can customize length, boat and pad colors, engine type and brand, battery count, numbers and more. Four different models are currently available on the Tanaruz app. The hull can be modified from 4.5 to 7.5 meters; open and inside cabins are possible, with a capacity of 3 to 8 people. Motor-battery combinations make the vessel suitable for journeys of up to 30 km and most hull impressions can be completed in 40 hours. The app even goes so far as to estimate the final price (from around $20,000 to over $60,000), which really makes you want to click through and get one.
The 3D printer deployed at Tanaruz is a robotic LFAM system using an ABB multi-axis robotic arm. The motion track manufactured by ABB is the only track on the market with a guarantee of high speed, precision and flexibility. Unique ABB characteristics are leveraged to optimize the motion, path accuracy and speed of the robot arm. The robot arm, having been specially designed for Tanaruz, has the ideal parameters for the 3D printed yacht.
With its high precision and fast cycle time, the Tanaruz production line is expected to be very productive. The extruder, made by Dutch company Xtrution, handles the process of melting and extruding materials to Tanaruz specifications. It was built to ensure a stable and accurate boat impression.
Sounds too good to be true? It probably is, but only for now. The people behind Tanaruz are really serious about this. Their idea may still be a little raw, but it’s about to get sea legs.
