3D LimitLess was chosen as partner of the ITG (Instituto Tecnológico de Galicia) for the design and development of the waterproof housing and its attachment to the surfboard for their FlyThings Surf device, using 3D printing manufacture , and parametric 3D design.
FlyThings Surf is a solution consisting of a hardware device (a sensor of 51 gr of weight, 6 cm in diameter and 2 cm of thickness that is installed in the tip of the surfboard) and a software that represents over the video image the values reached by the surfer in each of their maneuvers. The information obtained allows an objective assessment of the effort, skill and performace of these athletes.
The sensor, high accuracy and low consumption device, records 50 data per second. During the championship, a total of 13.58 million data have been analyzed and treated with AI techniques resulting in understandable statistics for the viewer. Some of the waves best scored by the judges during the championship have been carried by surfers with the device on their surfboard.
FlyThings Surf brings information that doesn't have any other championship in the world yet.

Félix Rodríguez Fernández, ITG Communication Manager, said: "3D LimitLess helped us to improve our initial idea and today this is difficult to find in a supplier." "The advice received to meet the technical and economic objectives has exceeded our expectations."
It is a telemetry system synchronized with the TV images that allows to display objective and measurable information for surfers, speakers and viewers.
It allows to measure the force that the surfer apply to the surfboard and the speed of its turns.
From the point of design and manufacturing through 3D printing, 3D LimitLess had to solve several challenges. The premises were, among others, to guarantee the waterproof and the functionality of the device submited to shaking and rough handling, exposure to the unfavorable marine environment (wind, water, salt, sand), having a form factor as minimal as possible to avoid discomfort to the surfer, easy opening for the technicians intervention when operating with the device during the competition and a simple and quick fastening method to the surfboard, while it was safe enough to avoid to get lost accidentally or move during a championship.
We made the 3D design in context, starting from the electronic circuits developed by the ITG, achieving an optimal fit and tolerances. After obtaining the 3D digital model of the enclosure's components and the support for the surfboard, several 3D prints were made with our 3D printer 3D LimitLess ILC in order to validate the design, placing with the electronic board and perform the first tests of tightness and functionality. For the tests, ASA and ABS printing materials were used, which are technical materials with sufficient quality to evaluate the functionalities and tests necessary before production.
Once obtained the final model after several interactions, and validation by the ITG, the necessary units of the FlyThings Surf case were 3D printed for the competition, using industrial 3D printing. 3D printing was performed using laser sintering (SLS) 3D printers in polyamide PA12 (nylon).
This material is very resistant and has a similar finish to a product made by traditional manufacturing methods, thus achieving the required functionality and strength, giving a device with an aspect of final product. In addition, the additive manufacturing technology was able to keep the cost as low as expected, and made in a very short time span; with technologies such as extrusion molding or CNC machining, these objectives wouldn't be met.
ITG has signed an strategic alliance for the next 4 years with the Pull & Bear Pantín Classic Galicia Pro organization, which is the most relevant championship in Spain and the oldest in Europe, which has celebrated its 30th anniversary this year, placing itself at the summit of the innovation.
The solution that has been adopted in this edition is the FlyThings Surf first version. Next developments will allow to quantify and to differentiate much more information with a reduction of the size of the device by 50%.
3D LimitLess intends to follow the line of collaboration initiated with the ITG, and to continue with this synergy in the following projects, using the additive manufacturing as a fundamental technology for the development of this product and others as well.
Welcome to the LimitLess revolution!
