  This study is devoted to the search for new scientific and technical
solutions in the field of renewable energy sources, in particular biofuels.
Biomass is the main fuel for green energy, accounting for two thirds of the
energy produced from renewable sources. The further development of the industry
depends on the improvement of the equipment and technologies used in it. On the
example of a cleaning apparatus, a new technology for prototyping its parts
using a robotic module is shown and tested. The use of plastics as parts of
technological equipment is a modern trend and may be due to the low adhesion
strength of various substances to the surface of these parts due to poor
wettability and low values of the surface energy of these materials compared to
metals.
