Open Source Rust 3D Printing Software

Encrust is a free, open-source slicer for MSLA and SLA resin 3D printers. It checks every layer of the file it writes for islands, suction cups, thin walls and hard peel before you print, and that check runs in the same pass as the slice: a million-triangle model is sliced, written and checked in 0.72 seconds on an eight-core computer. Supports, hollowing, drain holes, auto-orientation and a command line are all included. There's no paid tier, no account and no cloud, and your files never leave your computer. Encrust runs on Windows, macOS and Linux, and in the browser at encrust.app/app. Encrust is in alpha. The whole pipeline works and has printed real parts, but only one printer (ELEGOO Saturn 4 Ultra) is confirmed so far. Start other printers with a small calibration print.

Project Description 3DPrintOps Manager – Community Edition is a free Windows desktop application designed to help 3D printing enthusiasts, makers, and small print operations manage their day-to-day printing activities efficiently. The application provides structured tools for tracking printers, filaments, print jobs, vendors, and operational costs. Users can log print outcomes (successful, partial, or failed), maintain a smart shopping list with historical ratings, and generate cost insights based on material usage, print time, and electricity rates. 3DPrintOps Manager runs entirely offline and stores all data locally on the user’s machine. No cloud services, accounts, or internet connectivity are required. The software is distributed as a community edition, free for personal and internal business use, and is provided as a prebuilt Windows installer. This project is intended for: 3D printing hobbyists and makers Small workshops and print farms Users who want simple
