High performance 3D printing

Fabricating materials with special properties, such as heat-resistance, flexibility, and high tensile strength, traditionally requires production-grade 3D printers or other manufacturing techniques. This tutorial is an introduction to open source 3D printing and describes:

  • How to install a high-temperature heater block and nozzle on an open-source 3D printer

  • How to connect a thermistor and amplifier to the Rambo circuit board

  • How to modify and flash printer firmware.

High-temperature 3D printing allows a much wider range of materials than standard 3D printing.

Blockchain File System


Using a public blockchain as a file system confers the advantages of permanence and global accessibility by any computer with an internet connection in exchange for the relatively high cost of uploading data. Analog Labs benefits from the blockchain data structure’s properties in order to securely archive information generated by research activities and to make this information publicly accessible. This article describes:

  • How to encrypt data using the AES-256 cipher.

  • How to upload data to the public Ethereum blockchain.

  • How to download data from the public Ethereum blockchain.
