“…Since the Agro-toolbox will be used in an external environment exposed to sunlight and high temperatures, especially during the summer period, PETG (Poly Ethylene Terephthalate Glycol) was selected as the construction material. PETG is known for its durability and ability to withstand high temperatures [ 22 , 23 ]. The PETG material used was in filament form with a diameter of 1.75 mm and yellow color.…”

The agricultural sector faces numerous challenges in ensuring optimal soil health and environmental conditions for sustainable crop production. Traditional soil analysis methods are often time-consuming and labor-intensive, and provide limited real-time data, making it challenging for farmers to make informed decisions. In recent years, Internet of Things (IoT) technology has emerged as a promising solution to address these challenges by enabling efficient and automated soil analysis and environmental monitoring. This paper presents a 3D-printed IoT-based Agro-toolbox, designed for comprehensive soil analysis and environmental monitoring in the agricultural domain. The toolbox integrates various sensors for both soil and environmental measurements. By deploying this tool across fields, farmers can continuously monitor key soil parameters, including pH levels, moisture content, and temperature. Additionally, environmental factors such as ambient temperature, humidity, intensity of visible light, and barometric pressure can be monitored to assess the overall health of agricultural ecosystems. To evaluate the effectiveness of the Agro-toolbox, a case study was conducted in an aquaponics floating system with rocket, and benchmarking was performed using commercial tools that integrate sensors for soil temperature, moisture, and pH levels, as well as for air temperature, humidity, and intensity of visible light. The results showed that the Agro-toolbox had an acceptable error percentage, and it can be useful for agricultural applications.

“…The materials used were PETG (poly ethylene terephthalate glycol) and PLA (polylactic acid) in filament form with a diameter of 1.75 mm. PETG was chosen for the external parts because it is a durable material and is also recyclable and reusable [31,32]. PLA was selected because it is an environmentally friendly material and has biodegradable properties [33,34].…”

Hyperspectral imaging has revolutionized various scientific fields by enabling a detailed analysis of objects and materials based on their spectral signatures. However, the high cost and complexity of commercial hyperspectral camera systems limit their accessibility to researchers and professionals. In this paper, a do-it-yourself (DIY) hyperspectral camera device that offers a cost-effective and user-friendly alternative to hyperspectral imaging is presented. The proposed device leverages off-the-shelf components, commercially available hardware parts, open-source software, and novel calibration techniques to capture and process hyperspectral imaging data. The design considerations, hardware components, and construction process are discussed, providing a comprehensive guide for building the device. Furthermore, the performance of the DIY hyperspectral camera is investigated through experimental evaluations with a multi-color 3D-printed box in order to validate its sensitivities to red, green, blue, orange and white colors.

“…The material chosen for these experiments is PETG, a glycol-modified PET thermoplastic [23]. PETG is a well-known polymer, most often used for medical products or food applications due to its transparency, chemical, and structural resistance [24]. Extrusion-based polymer 3D printing (also referred to as BAAM -Big Area Additive Manufacturing or LSAM -Large Scale Additive Manufacturing) is a process where feedstock material is heated up in an extruder and deposited successively line by line, layer by layer.…”

The decarbonisation of the building sector requires the development of building components that provide energy efficiency while producing minimal environmental impact. We investigate the potential of polymer 3D printing (3DP) for the fabrication of mono-material translucent facade components, whose properties can be tailored according to climatic conditions and functional requirements. These components bear the potential to reduce energy consumption in buildings and, at the same time, can be fabricated with minimal environmental impact thanks to the recyclability of the feedstock material. In this study, we explore the effect of component geometry on the thermal insulation properties of 3DP objects with bespoke internal structures. Different prototypes are fabricated using a robotic polymer extruder, and their thermal properties are measured following a hot-box test method. The experimental results are then used to calibrate a heat transfer simulation model describing the joint effects of conduction, natural convection and infrared radiation through the components. We show that it is possible to fabricate insulating polymer components providing thermal transmittance ranging from 1.7 to 1 W/m2 K only by changing the internal cavity distribution and size. This proves the possibility of designing 3DP thermally-insulating components for different climatic conditions and requirements. This study provides the first insights into the thermal behaviour of polymer 3DP facades on a large scale. The results suggest that this innovative manufacturing technique is promising for application in facades and encourages further research toward performant and low-embodied energy 3DP building components.
