OctoPrint is an open source project for the web-based control of commercially available 3D printers . It was started by Gina Häußge in 2011 as a Cura - Fork and has been looked after by her ever since. From 2014 to 2016 the development was financed by the consumer electronics manufacturer BQ , for which Häußge worked until 2016. In April 2016 she wrote a blog post to her community and asked for support for her project via the Patreon donation platform ; since then the project has been financed by monthly donations from more than 1700 supporters. As of February 2020, approximately $ 5,500 are being donated monthly.

functionality

OctoPrint can either be installed manually on a computer or set up on a Raspberry Pi with the OctoPi image . After the installation, OctoPrint starts a local web server and enables a USB-connected 3D printer to be controlled via a web interface.

In addition to the automated transmission of G-Code , OctoPrint offers options for manual control and monitoring of the 3D printer. A webcam can also be integrated to receive a live image from the printer and, for example, to create time-lapse recordings. Octoprint offers extensive setting options and enables the creation of profiles and users.

The functionality of OctoPrint can be expanded with plugins, for example from the official plugin register.

compatibility

OctoPrint has been tested with a variety of 3D printers, including the Ultimaker 2, Prusa i3 and the 3DR Reprap. While there are usually no compatibility problems with 3D printers with an open source firmware such as Marlin , the connection with many 3D printers that use proprietary protocols (e.g. the Makerbot Gen 5) is usually not possible.

The software has a REST API interface and thus enables control by other applications, for example by an Android app or a smartwatch. MyMiniFactory , a provider of models for 3D printing, has been offering its users a plug-in for OctoPrint since November 2018, with which users can send models from the website directly to an OctoPrint instance. The slicing is done by MyMiniFactory, the feature is called "Click & Print". Integration into the home automation software ioBroker is also possible using a plug-in.

Security risks

In September 2018, the Internet Storm Center (ISC) of the SANS Institute reported that numerous OctoPrint instances can be accessed publicly via the Internet without authentication. A total of 3759 freely accessible instances were registered, 357 of these instances were located in Germany according to the ISC. The publicly accessible instances are problematic because strangers could control the connected 3D printer, access a connected webcam or download the printed files. If necessary, it is possible to manipulate the firmware of connected 3D printers.

OctoPrint does implement access management, but this also enables non-registered users to read the uploaded files, the webcam and the connected 3D printer. In addition, this access management can be completely deactivated.

The developers OctoPrints responded with a blog posting in which they warned of port forwarding - which the instance usually makes publicly available. Instead, the developers recommend setting up access via special plugins or a secure connection (e.g. VPN ).
