Selecting the correct voltage for your 3D printer is a very important step in order to have a fully functioning machine and many users still are unsure about the voltage of the country they live in. That’s why I wrote this article, to teach users about the 3D printer voltage numbers for different countries.

The 3D printer voltage numbers are either in the range of 110 – 120 volts (V) or 220 – 240V. It is important to select the right voltage according to the country you are in. In the United States, the standard voltage is 120V while in the United Kingdom and Australia, it is 230V. 

This is just the basic answer, keep reading for more detailed information about 3D printer voltage numbers for countries such as the US, UK, Australia & more.

3D Printer Voltage Numbers for Country – US, UK, Australia & More

Different countries have varying standards for electrical systems, and understanding the voltage numbers for countries like the US, UK, Australia, and more is crucial to ensure your 3D printer operates safely and efficiently.

Voltage, also known as electric potential difference, is a measure of the electric potential energy per unit charge.

In practical terms, it determines how much electrical pressure is supplied to a device.

Most countries have standardized their voltage systems to ensure compatibility and safety. The two main voltage standards are 110 – 120 volts (V) and 220 – 240V.

Let’s take a look at the voltage numbers for different countries and regions, including:

• United States
• United Kingdom
• Australia
• European Union
• Japan
• China
• South America
• Middle East and Africa

United States

In the United States, the standard voltage is 120V with a frequency of 60 Hertz (Hz). This voltage is commonly used for residential and commercial purposes. 

If you’re setting up a 3D printer in the US, you’ll need to ensure it’s compatible with this voltage range.

One user stated that selecting the correct voltage is not a matter of preference as the voltage switch in your printer must match your main voltage or you may cause damage to the printer.

Another user said that in the US and Canada, the official nominal is 120V but allowable over a range from 114V to 126V.

United Kingdom

The United Kingdom operates on a standard voltage of 230V with a frequency of 50Hz. 

This higher voltage allows for more efficient energy transmission and is the norm for most European countries. If you’re in the UK, it’s essential to check your 3D printer’s voltage compatibility and use appropriate voltage converters if necessary.

Users from the UK recommend always leaving the voltage at 230V as that is the standard for the country.

Australia

Australia utilizes a standard voltage of 230V as well, similar to the UK, but with a frequency of 50Hz. 

It’s worth noting that Australia follows the British standard, and this voltage is prevalent across the continent. 3D printer enthusiasts in Australia must make sure their equipment can handle this voltage to prevent damage.

One user ended up causing damage to his printer’s PSU by running his Ender 3 at 115V when his country’s main voltage was 230 – 240V.

He ended up needing to replace the power supply of his printer.

European Union

The European Union has standardized its voltage at 230V with a frequency of 50Hz. 

This standardization makes it easier for countries within the EU to exchange electrical equipment without worrying about voltage compatibility. In case you’re in an EU country, your 3D printer setup should align with this voltage specification.

Users from different countries of the European Union, such as Germany and the Netherlands, recommend only using your 3D printers at 230 volts.

That’s because that is the standard voltage for all the countries in the EU and you may risk damaging your printer if you switch it to the wrong voltage.

Japan

Japan stands out with a voltage of 100V and a frequency of 50Hz or 60Hz, depending on the region. This unique voltage requirement can pose a challenge for 3D printer users who need to adjust their equipment accordingly if they’re in Japan.

One user stated that when turning on your 3D printer in Japan, always keep the voltage to 120V as the standard voltage for the country is at around 100-120V.

China

China primarily operates on a voltage of 220V with a frequency of 50Hz. 

As a rapidly growing hub for manufacturing and technology, China’s voltage specification is important to understand for those planning to set up a 3D printer in the region. Most places in Asia also use 220V as the standard voltage. 

One user, who is from the Philippines, stated that he uses his Ender 3 V2 with the voltage switch on 230V as his country has 220V as the normal voltage.

He also stated that the reason that 3D printers show 230V instead of 220V is to amount to spikes or variations in voltage depending on where you live.

South America

Voltage standards in South American countries can vary significantly. While many countries use 220V, there are exceptions. Brazil, for instance, uses both 110V and 220V. 

This diversity necessitates thorough research when setting up a 3D printer in South America.

One user stated that the reason that 3D printers come with a power switch with two voltage options is for international use, that way, no matter the country everyone can use a 3D printer.

If you live in South America or are visiting soon and planning on 3D printing there, checking this list of voltages may be helpful.

Middle East and Africa

Voltage standards in the Middle East and Africa are diverse due to varying historical influences and infrastructure development. 

While some countries adhere to 230V, others might have different standards. This region requires careful consideration of voltage compatibility when establishing a 3D printing setup.
