Recently, researchers at Michigan Technological University successfully tested and shared the first open-source solar 3D printer
.
The research team explained that many people in developing countries live off-grid (no power grid), for them, 3D printers are useless
.
About 1 billion people worldwide do not have access to electricity, but the cost of solar PV power systems is getting lower and lower, and this will be an effective solution
in the future.
"The International Energy Agency (IEA) predicts that sub-Saharan Africa's population growth will far outpace the power of electricity supply by 2030, with 75% of the region's population without access to electricity
by 2040.
"
In order to minimize energy consumption, the research team has also made a lot of considerations in the solar 3D printer itself, such as: improving the surface treatment of the print bed, using low-temperature filaments such as biodegradable PLA, reducing the number of stepper motors, and so on
.
The battery they use is a polymer lithium-ion rechargeable battery (14.
8 V, 20 Ah), which prevents overcharging and can be used as an energy backup
in the absence or low amount of light.
It is reported that the production cost of the entire solar photovoltaic power generation system is about $1,000 (including the RepRap 3D printer), of which the cost of solar cells is the highest
.
Seeing this, perhaps the most concerned question is: can solar 3D printers really rely only on solar energy to maintain stable operations? The answer to this question is: Yes
.
The team did different experiments in a variety of situations, such as relying only on PV batteries to work, relying only on light to work, etc.
, and the results proved that no matter what the state, the 3D printer can work normally
