History

OctoPrint was created by Gina Häußge in 2012,[2] who initially developed the software to support her first 3D printer. OctoPrint[3] was forked from Cura, and is available under the same AGPL license. Development is hosted on GitHub.[3] Between August 2014 and April 2016, Spanish smartphone manufacturer BQ financially supported OctoPrint development by employing Gina Häußge full time to work on it. When BQ discontinued support in April 2016, Häußge turned to Patreon.[4][5]

In September 2018, a vulnerability was publicized at the Internet Storm Center of SANS Institute because "thousands" of users misconfigured their OctoPrint interface so it was available to the Internet without a login. This could result in not only a loss of data (intellectual property of designs) and privacy (through a connected webcam), but literal fires from poorly designed 3D printer safety controls.[6][7][8][9][10][11][12] Solutions that still enable worldwide access to a printer include using a commercial cloud printing interface like AstroPrint, Polar Cloud, or 3DprinterOS as well as the OctoPrint Anywhere plugin or standard VPN installations.[13][14]

Starting with OctoPrint version 1.4.0 released on March 4, 2020, OctoPrint is compatible with Python 3.[15] At the time of the release, most OctoPrint plugins were already compatible with Python 3.

As of August 2023, the OctoPrint Patreon campaign receives over $5,200 per month from over 1,900 backers.[16]

Features

OctoPrint provides a web interface for controlling 3D printers, allowing the user to start a print job by sending G-code to a 3D printer connected via USB. OctoPrint monitors the status of the print job, as well as the printer itself, including the temperature of the print head (hot end) and the temperature of the bed, if the bed on the printer is heated. OctoPrint can also show the output of a connected webcam in order to monitor the state of the print, and can visualize the G-code in sync with the print job, or asynchronously.

OctoPrint has a plugin system, allowing users to extend functionality. As of December 2023, there are 383 plugins listed in the official plugin repository.[17]

The 10 most popular plugins on the official plugin repository for December 2023[17] (ordered by number of installs) are as follows:

  1. OctoEverywhere(48.69k installs): A system for remotely monitoring and controlling your OctoPrint instance.[17][18]
  2. PrintTimeGenius(39.98k installs): Uses g-code analysis to enhance the accuracy of the print time estimation.[17][19]
  3. Bed Level Visualizer(37.39k installs): Displays 3D mesh of bed topography report.[17][20]
  4. OctoPrint-Dashboard(28.09k installs): Shows the info regarding the state of the printer and on-going print job at a glance.[17][21]
  5. Octolapse(27.27k installs): Create a customizable stabilized time-lapse of the 3D prints.[17][22]
  6. Firmware Updater(26.84k installs): Update your printer's firmware from OctoPrint.[17][23]
  7. DisplayLayerProgress(18.84k installs): Displays the Layer, Progress and other data on the printer display and the OctoPrint interface.[17][24]
  8. Themeify(17.88k installs): Change the looks of OctoPrint.[17][25]
  9. Obico for OctoPrint(16.25k installs): A system for remotely monitoring and controlling your OctoPrint instance.[17][26]
  10. Slicer Thumbnails(16.2k installs): Extracts various slicer's embedded thumbnails from g-code files.[17][27]

It has also been used by Thomas Sanladerer in a PrintrBot as a self-contained and fully mobile printer build.[28][29]

OctoPrint can run on a variety of systems, but is commonly run on Raspberry Pi. A distribution called OctoPi based on the Raspbian OS for Raspberry Pi, provides a pre-configured version of OctoPrint along with an mjpg-streamer support for webcams.[30]

OctoPrint recommends using the Raspberry Pi 3B, 3B+, 4B, or the Zero 2 and specifically warns against using the Raspberry Pi Zero W due to severe performance issues observed.[31]

This is the case right now for OctoPrint, who has apparently lost their sponsor, BQ, and is taking to Patreon for support in what is a bit of an emergency funding situation or we may lose this startup to current lack of capital. According to word on the street—or, today that would be on Reddit—those who are fans of the 'snappy web interface' for their 3D printers put the word out leading us to a social media announcement from founder Gina Häußge. There is undeniable concern for the future of what is currently quite a popular source of 3D printing host software.

Putting OctoPrint onto the public internet is a terrible idea, and I really can't emphasize that enough. Let's think about this for a moment, or two, or even three.

Earlier this month, security experts found a way to use OctoPrint to take print files off printers remotely or replace them with compromised files. An enterprising reporter even managed to do this inside two corporations that they left unnamed. Granted, these breaches stem from an unintended use case for OctoPrint

It turns out they've made a plug-in for OctoPrint that is installable by the touch of a button. Once done, your OctoPrint installation is then connected to the AstroPrint cloud and you can then use their mobile app to remotely control your 3D printer, for example. But you can also bring forward all their other functionality, which is considerable.

In a brilliant article on OctoPrint.org, contributor Jubaleth describes how many OctoPrint installations are actually publicly exposed to anyone by improper methods of Internet connection. Typically an uninformed operator might simply forward the OctoPrint ports through their network router to the public Internet.
