MSLA/DLP, file analysis, calibration, repair, conversion and manipulation

This simple tool can give you insight of supports and find key failures.
Did you forget what resin or other settings you used on a project? This can also save you, check every setting that was used with or change them!

Why this project?

I don't own a Prusa SL1 or any other resin printer, for now I’m only an FDM user with Prusa MK3 and an Ender3. PrusaSlicer is my only choice, why? Because I think it's the best and features more, at least for me, simple but powerful.

So why this project? Well, in fact, I’m looking for a resin printer. I like to study and learn first before buying and get good and don't regret. While inspecting, I found that resin printers firmwares are not as universal as FDM, too many file formats and there before each printer can use their own property file, this of course limit the software selection. For example, only PrusaSlicer can slice SL1 files. So with that in mind, I'm preparing when I get a resin printer in the future, I can use PrusaSlicer instead of others. I've explored the other slicers and again, no one gives me joy, and I feel them unstable, many users slice model on PrusaSlicer just to get those supports and export STL to load in another, that means again PrusaSlicer is on the win side, the problem is they can't slice directly on PrusaSlicer, so, in the end, my project aims to do almost that, configure a printer on PrusaSlicer, e.g.: EPAX X1, slice, export a file, convert SL1 to native printer file and print.

Please note I don't own any resin printer! All my work is virtual and calculated, so, use experimental functions with care! Once things got confirmed, a list will show. But also, I need victims for a test subject. Proceed at your own risk!

sudo bash -c "$(curl -fsSL https://raw.githubusercontent.com/sn4k3/UVtools/master/Scripts/install-dependencies.sh)"

To run UVtools, open it folder on a terminal and call one of:

• Double-click UVtools file
• ./UVtools
• bash UVtools.sh
• dotnet UVtools.dll [For universal package only, requires dotnet-runtime]
• As a practical alternative, you can create a shortcut on Desktop

If you download the .AppImage package variant, you must set run permissions to it before attempting to run it:

Mac

1. macOS 13 Monterey or higher
2. 8GB RAM or higher + 512MB per CPU core
3. Install UVtools via the auto installer

To run UVtools, open its folder on a terminal and call one of:

• Double-click UVtools file
• ./UVtools.app/Contents/MacOS/UVtools
• bash UVtools.app/Contents/MacOS/UVtools.sh
• As a practical alternative, you can create a shortcut on Desktop

How to use

There are multiple ways to open your file in UVtools:

1. Open UVtools and load your file (CTRL + O) (File → Open)
2. Open UVtools and drag and drop your file inside the window
3. Drag and drop the file into UVtools.exe
4. Set UVtools the default program to open your files

Library -> Developers

Are you a developer? This project includes a .NET library (UVtools.Core) that can be referenced in your application to make use of my work. Easy-to-use calls that allow you to work with the formats. For more information, navigate the main code to see some calls.

Nuget package: https://www.nuget.org/packages/UVtools.Core

dotnet add package UVtools.Core

Scripting:

• PowerShell
• Python

Develop and build from Source

Build directions
The fastest way to compile the project is by run the build/compile.bat, however, if you wish to develop with Visual Studio follow the following steps:

1. Install Visual Studio and include .NET development support
2. Install the .NET 6.0 SDK if not included on the previous installation
3. Install the Avalonia for Visual Studio:
4. Install the Wix Toolset: (Required only for MSI build, optional)
   • dotnet tool install --global wix
   • Visual Studio HeatWave extension
5. Open UVtools.sln
6. Build

TODO

• More file formats
• Cleanup and performance (always)
• See features request under GitHub
