Bambu Studio
PC Software for BambuLab and other 3D printers
Bambu Studio is a feature-rich slicing application designed to provide a smooth, project-based 3D printing workflow. It is built on PrusaSlicer and Slic3r foundations while adding Bambu Lab’s own interface, optimized slicing behavior, and printer-focused tools. The software is especially suited for Bambu Lab printers, but its open-source base also makes it relevant to the broader 3D printing community. It helps users prepare models, manage projects, adjust slicing settings, preview toolpaths, and send print-ready files to compatible machines. Bambu Studio emphasizes ease of use without removing advanced controls needed for more complex prints. Its main value is giving users a polished slicing environment that connects model preparation, slicing, and printer operation in one place. -

Jmol
An interactive viewer for three-dimensional chemical structures.
Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export). -

ESP3D
FW for ESP8266/ESP8285/ESP32 used with 3D printer
This firmware allows not only to have a cheap bridge between Wifi and serial, but also to have a web UI to configure wifi, to monitor 3D printer and even control it, and to make things easy, UI is fully customizable without reflashing FW. Firmware should work with any 3D printer firmware (repetier/marlin/smoothie ware using GCODE) if the serial connection has a correct setup. I currently use it with my personal flavor of repetier for Due based boards. The web interface files are present in the data directory but UI has its own repository ESP3D-WEBUI. Use GPIO2 to the ground to reset all settings in a hard way, 2-6 sec after boot / not before!! Set GPIO2 to ground before boot change boot mode and go to special boot that do not reach FW. Currently, boot takes 10 sec - giving 8 seconds to connect GPIO2 to GND and do a hard recovery for settings. Complete configuration by web browser (Station or Access point) or by Serial/telnet commands. -

ImatiSTL
Fix STL files for 3D printing
ImatiSTL is a C++ library for applications that need to finely post-process raw polygon meshes represented by STL files. It is particularly useful in 3D printing scenarios: the repairing functions provided by ImatiSTL bridge the gap between printable meshes and real-world meshes with diverse potential defects and flaws (e.g. degenerate triangles, self-intersections, surface holes, ...). ImatiSTL provides both functions for local mesh repairing and methods for global remeshing. Local repairing is useful when the available data must remain exactly as it is in the input STL file, whereas global remeshing may fix even highly corrupted meshes at the cost of a small distortion in the resulting fixed mesh. -

GComb
GComb is a gCode viewing tool with an interior focus
GComb is an open-source quick and easy Java tool intended to ease the lives of all 3D printing hobbyists by providing a look inside a “sliced” GCode file and a better view of what is going to be printed, before it is printed. It works by parsing GCode files and producing an image for each layer of the printed object, any of which can then be viewed. GComb was originally written on Mac OS X using Eclipse with Java version 1.7.0_25, and was made for a Makerbot™ The Replicator Dual printing Skeinforge 50-generated GCode files. The jar file in the package was compiled for use by Java versions 1.5 and greator but, its compatibility on different operating systems and utility for different printers and slicers than those it was written for is not assured. However, we coders did our best to make sure that our implementation would not depend on comments in GCode or slicer-specific details, so it should work given files generated by Slic3r and others as well as Skeinforge. -

Q*Bot 3D Printer
Q*Bot 3D Printer Repository
After a couple of years that I follow 3D printer growth, I picked up all the best solutions, as magnetic joints and prismatic linear guides, and gather together in this project. A complete 3D Delta Printer that can be built with about 200 euro (with electronics and graphical display, hotend and motors excluded). Printable area: 200mm dia and 200mm height Q*Bot is based on commercial Aluminum "L" profile, 25x25x4, which work as structure and linear guides as well. It's steady, fast and easy to build. Here you can find related files, including Bill of Materials, CAD drawings and all 3D printing objects needed. It's intended to be an open project: who wishes to collaborate with ideas and improvements, is welcome! Discussion and other details here: http://forums.reprap.org/read.php?362,479919
