Non-Invasive Monitoring of Aquaculture Systems

NIMAS aims to realise non-invasive aquaculture monitoring with submersible cameras for best conditions of fish and sea-food in such environments. In this, an airtight, submersible underwater camera housing is planned to be realised through additive manufacturing. This will allow for an application optimized design specifically for monitoring of aquaculture fish farms.

Original prototype housing manufactured using traditional machining methods resulted in a product that was slow and expensive to produce. MonitorFish wishes to create an improved design that minimizes buoyancy while also improving assembly of the electronic components. Additionally the aim is to take advantage of additive manufacturing to optimize the design and integrate novel design features, while improving manufacturing speed and costs.

Challenges that the team currently faces

  • FFF technology although inexpensive and practical for producing prototypes typically does not produce airtight, hermetically sealed parts. For this result, post processing is usually required to produce the desired result.
  • The post-processing not only increases production time and costs, but also affects the final dimensions of the part by either addition or removal of material from the print. Furthermore, some post processing techniques such as acetone vapour smoothing requires the use of specific materials like ABS, thus limiting the materials that can be used.
  • The main challenge is to use Orion’s technology to produce a hermetically sealed enclosure capable of withstanding hydrostatic pressure up to 10m depth without any post processing required. The solution should work with commonly available materials to FFF process.
