Precision agriculture is today one of the fastest-growing segments in the civil sector. Multispectral drones, IoT control units installed in fields, satellite guidance systems for tractors, sensors for monitoring soil moisture and automated irrigation systems are transforming the way agricultural activities are managed. However, many agritech projects face a common difficulty: much of the custom components needed aren't available off the shelf. You may need brackets designed to mount a sensor on a specific drone model, watertight housings for IoT control units exposed to the elements, mounts resistant to plant protection products and UV rays, or spare parts for older agricultural machines that are no longer available in stock.
Industrial 3D printing offers a concrete answer to these needs. It makes it possible to produce technical components for the agritech sector, even in small runs, using materials resistant to the environmental conditions typical of agriculture. All this with reduced production times, wide design freedom and a high level of customisation. On this page, we analyse the most requested components, the most suitable materials and the main operational advantages of 3D printing applied to agritech.
Modern agriculture is increasingly based on data, connectivity and automation. Sensors distributed across fields, assisted-guidance machines, drones for crop monitoring and automated irrigation systems require specific technical components, often non-standard and produced in limited quantities. These elements must also withstand demanding environmental conditions, such as humidity, dust, UV rays, temperature swings and chemical substances.
In the agritech sector, traditional production presents three main limitations:
Additive manufacturing makes it possible to overcome all three of these obstacles: zero tooling costs, delivery times in days (not months), quantities from 1 to thousands of parts and the freedom to put files back into production whenever needed, without tying up stock or physical spare parts.
The main families of technical components for agritech made today through 3D printing involve practically the entire ecosystem of precision agriculture.
Drones intended for precision agriculture represent one of the most dynamic segments of the sector, with new models, sensors and configurations introduced every season.
3D printing makes it possible to develop:
IoT stations in the fields must meet particularly rigorous requirements. The housings must be resistant to water, dust and UV rays, withstand years of outdoor exposure and adapt to different sensor configurations and fastening systems.
3D printing produces:
Tractors, combine harvesters, seed drills and sprayers have particularly long life cycles and generate a constant demand for custom spare parts, secondary components and technical accessories. 3D printing covers:
Irrigation, fertigation and fluid distribution systems often require custom components in limited quantities, generally in the order of a few dozen or hundred pieces, ideal for additive manufacturing:
A component intended for work in the agricultural field faces far harsher conditions than an element used in indoor environments. Four requirements influence the choice of material.
Prolonged solar exposure degrades most polymers: yellowing, embrittlement, loss of mechanical properties. For components intended for outdoor use, materials stabilised against UV rays or intrinsically resistant to solar radiation are needed. PA12 and PA11 with vapor smoothing offer good performance in outdoor applications; TPU and ASA are intrinsically excellent against UV.
Agriculture is an environment saturated with humidity: rain, condensation, irrigation, direct immersion. Some polymers, such as standard PA6 and PA66, can absorb significant amounts of water, resulting in dimensional changes and reduced stiffness. For agritech applications, materials characterised by lower absorption are therefore preferred, such as PA12 and PA11, PEEK and specific grades of hydrolysis-resistant TPU. Vapor smoothing can also reduce surface porosity and improve the water repellency and ease of cleaning of the component.
Plant protection products, fertilisers, soil improvers, oils, detergents: an agritech component is potentially exposed to many aggressive substances. PEEK and polypropylene offer high resistance to numerous chemical substances; PPS CF and Ultem guarantee excellent performance in the presence of solvents and aggressive agents; ESD PETG has good resistance to oils and hydrocarbons, but its compatibility with concentrated plant protection products must be assessed on a case-by-case basis.
Tractors, combine harvesters, internal combustion engines and drones operate in environments characterised by continuous vibration. A mount that's too rigid or designed without considering fatigue can develop cracks and break prematurely.
There are two main design strategies:
Based on the environmental, chemical and mechanical requirements typical of the agricultural sector, it's possible to identify the most suitable materials for each agritech application.

In the presence of particularly demanding conditions or prolonged chemical exposure, it's advisable to check the specific material grade with the technical team and assess the application of any additional protective treatments.
The real value of 3D printing for agritech isn't the individual part, but the development, production and management model it makes possible.
Customisation: every sensor, drone or agricultural machine has specific geometries, dimensions and fastening systems. With 3D printing, the mount or housing is designed around the device, without forcing the product to adapt to standard components. This makes it possible to develop perfectly integrated solutions, avoiding compromises on performance, ergonomics or the overall design of the system.
Economically sustainable small runs: Additive manufacturing makes it possible to produce from a single part to several thousand units without incurring initial costs for moulds or tooling. A pilot project consisting, for example, of 20 IoT stations distributed across a vineyard can use the same 3D printed housings that, if successful, can subsequently be produced in 2,000 units. The transition from prototype to series takes place without changing the production process or facing new investments in tooling.
Rapid iteration: To update a component, it's enough to modify the 3D file and start a new production run. Corrections, optimisations and adaptations can therefore be introduced quickly, following the pace of evolution typical of agritech projects. Development times are reduced and every new version can be tested directly in the field without waiting for the making of new moulds.
On-demand spare parts: Components can be stored as digital files and reprinted only when needed, eliminating the need to keep physical stock. This approach is particularly useful for specialised machines, drones produced in limited runs, older equipment and sensors no longer in production but still operational.
Delivery in a few days: The process can begin directly from uploading the 3D file, with immediate quoting and rapid start of production. With technologies such as MJF, many components can be produced in 1–3 working days, while special materials produced through FDM may require additional time. In this way, development cycles that with traditional processes would take months can be reduced to a few weeks.
A startup specialising in the development of IoT control units for vineyard monitoring needed to produce 200 watertight housings for soil moisture sensors. The components had to guarantee resistance to UV rays for at least five years of outdoor exposure and integrate custom fastening systems for vineyard posts. Production through injection moulding would have required an initial investment of around €15,000 for the mould, as well as a minimum batch of 2,000 pieces: a solution incompatible with the volumes of the pilot phase.
MJF 3D printing in PA12, on the other hand, made it possible to obtain an online quote, immediately start production and receive the components within a week. The unit cost remained sustainable even for a limited run, with the additional advantage of being able to modify and optimise the design between the test season and the subsequent full-scale production.
Similar situations arise every day in the development of mounts for multispectral sensors installed on drones, brackets for irrigation control units, covers for LoRaWAN antennas, custom spare parts for sprayers and numerous other agritech applications.
Agritech is one of the sectors in which 3D printing best expresses its potential: small runs, customisation, on-demand spare parts, rapid iteration and materials resistant to outdoor environmental conditions. Whether it's mounts for multispectral sensors installed on drones, watertight housings for IoT stations, custom components for agricultural machines or spare parts for equipment no longer in production, industrial additive manufacturing offers solutions that are hard to achieve with injection moulding in the times and volumes required by the sector.
Thanks to MJF technology with PA12, PA11 and TPU nylon and industrial FDM printing with PEEK, ULTEM and other technical materials, it's possible to produce functional, resistant components that are ready for use in the field. With production times of 1–3 working days, developing a new agritech component today requires hours of design, not months of production preparation.
