What is UPS?

5 Best UPS for 3D Printers - Do not Waste Your Time and Printing Materials!

A UPS (Uninterruptible Power System) is a battery backup power system that supplies power to electronics long enough for them to shut down properly whenever there is a blackout or the utility power fails.

A UPS system is handy as it helps prevent loss of important data, saves time and materials in 3D printing and reduces the stress a hard shutdown causes on your electronics.

A UPS is also a surge protector. It protects your connected electronics from power problems like abnormal voltages which can damage or reduce their lifespan.

How Does a UPS Protect a 3D Printer?

A UPS protects a 3D printer from the stress of a hard shutdown. In case of a blackout, the printer will continue running and finish printing the build.

If the printer is not running but it’s on, the UPS will give you time to shut it down properly. Some UPS systems are also capable of protecting a 3D printer from surges and other power problems that can damage it or reduce its lifespan.

How to Choose the Best UPS Unit for Your 3D Printer

You wouldn’t know the best UPS for your 3D printer without knowing the essential features that make up a good one. The features include:


There are 3 main types of UPS systems based on topology or categories according to the type of power protection you need. The 3 topologies are: line-interactive, double conversion, and standby.

Line-interactive and standby UPSs can only provide short periods of battery runtime whenever there is a blackout. When utility power fails, they turn on the inverter which prevents interruption by producing power. They are best for protecting non-critical electronic devices.

Double Conversion, also known as online UPS, provides the best level of power protection for all of your critical electronic devices. It operates on AC/DC power seamlessly and constantly regenerates new and clean AC power through its continuous duty inverter.


If you are a technical geek who owns more electrical devices than just your 3D printer then you want to invest in the best battery backup for 3D printer that offers a huge power capacity. Whenever utility power fails or you get a blackout, the UPS will have enough power to allow the graceful shutdown of all of your critical devices. A 1500VA/900 unit like the Tripp Lite SMART1500LCD would suffice.


This is number of minutes a UPS can support all of your connected devices with power whenever there is a blackout. The number of watts supported affects runtime. A UPS with a large wattage load will have a short runtime.

The minimum runtime for a decent UPS system should be 5 minutes, the required runtime 30 minutes and the potential runtime 60 minutes.

Isolation Transformer

This is a crucial feature. It exists in UPS systems mostly for safety reasons. It is used to transfer electrical power from a source of AC power to some equipment or device while isolating it from the power source. In essence, it prevents the load from generating harmful harmonics and only clean power is provided at the output.

Surge Protection

Almost all UPS systems feature surge protection. Surge protection is crucial as it keeps your connected devices safe from the effects of a power surge. A UPS system with 10 outlets like the Amazon Basics Line-Interactive UPS will have 5 surge protectors. One with 8 will have 4 surge protectors.

Ethernet Protection

If you are planning to connect a network device like a modem or Ethernet then you must ensure you get a UPS system with enough power output and runtime otherwise, they will go down.

Management Software

Management software makes the UPS system easy to operate. You can access all the information about the unit and even customize alerts using the app. Most units come with a free download and they are usually compatible with various devices that you can connect to via USB.

Dimensions and Weight

This is an essential factor, especially if you have a small workspace cramped up with lots of electronics. If that’s the case, then you want to invest in a lightweight and compact unit like the Amazon Basics Line-Interactive UPS that can fit neatly into any space.
