Anyone recommend a good YouTube for learning how to cut STL's apart in meshmixer?

Hi folks!

I did a little programming over the weekend and now I would like to share the results with you.

What it is about

I have extended the awesome Photon File Validator Tool from Photonsters by the import of Prusa SL1 file format, so that the files generated by PrusaSlicer can be read in directly, without detour via ChituBox or other slicers that support .photon file format. Additionally I have implemented a Print Host, which pretends to be a Prusa SL1 printer to PrusaSlicer, so that the file can be sent to the Photon File Validator with one click, without a roundtrip via file system.

Motivation

The PrusaSlicer is - thanks to its excellent algorithms for auto-alignment and auto-support - very popular among Anycubic Photon users. Unfortunately, the currently common pipeline for print preparation is very cumbersome. Normally it works something like this:

1. Open the model in the MeshMixer or similar, hollow it out, put drainage holes in it and save it again.
2. Open the model in the PrusaSlicer, align it, generate support and save it again.
3. Open the model in ChituBox, adjust print parameters, slice and save.
4. Open model in Photon File Validator, correct errors and save.
5. Print

Even once, it's already time consuming. But if it turns out that there are still unsupported areas (and usually you will find this in the Photon File Validator, that's what the tool is for), you have to start from step 2 again. The whole open/save orgy over dozens of programs is very time consuming and just not fun. I wanted to change that.

Thanks to the new features in PrusaSlicer 2.2+ an external program for scooping out and drilling is no longer necessary, the slicer can do that by itself now. And thanks to the SL1 import into Photon File Validator you can do without proprietary slicers as an intermediate step, so it reduces the pipeline as follows

1. Open the model in PrusaSlicer, prepare it completely and transfer it to the Photon File Validator with a click on "Send to Printer".
2. Correct any errors in the Photon File Validator and save the .photon file.
3. Print

If there are some unsupported areas, simply switch to the PrusaSlicer window, fix the problem and click on "Send" again. This will reduce the time needed significantly.

Warning / Disclaimer

The software is still beta, and may contain smaller (and possibly larger) bugs. I do not take any warranty for functionality, possible damage to the printer etc. USE AT YOUR OWN RISK.

Installation

Currently no installers are provided. You need an installed Java-Runtime in version 11 or later to run the program. Download the JAR file and start the program with java -jar PhotonFileValidator.jar from the command line.

The complete source code (only necessary for developers) can be downloaded from my GitHub repository.

Usage

1. Start Photon File Validator with java -jar PhotonFileValidator.jar from the command line

2. The main window opens.

3. In the main window, click on Settings The setup dialog opens.

4. Make sure that "Print Host Settings / Current State" shows "Print Host is Running". If a problem occurs, change the port and restart the Print Host.

5. Under "Print Host Settings / Output directory", select the directory where the generated .photon files will be saved.

6. Click the button "Show PrusaSlicer settings" and follow the instructions to set up PrusaSlicer.

Basically you only need to adjust two entries in the default Prusa SL1 printer profile:

1. Set gamma correction to zero. This disables the anti-aliasing in the PrusaSlicer, as the anti-aliasing settings cannot be applied at the moment. However, this is not a limitation, as the built-in calculation in the Photon File Validator provides much finer control over the anti-aliasing settings. The import of gamma correction values is the next item on my TODO list.

2 (Optional) In the "Print Host upload" section, set the "Hostname, IP or URL" field to "http://localhost:8080" (or the port number you set). This setting allows you to send the file to Photon File Validator with one click after slicing, without having to save and reopen it.

Need help with something! I have a file here with an back part that seems to have no thickness, so I was hoping to cover it up by making it solid on Meshmixer. However, the whole file seemed to become "jagged" once I clicked on the option and quite a lot of details (like the eyes) seems to be lost. Is there anything that can be done to make the thin shells solid/ have thickness while not losing any detail?

需要幫忙! 我這裡有一個背部部分似乎沒有厚度的檔案, 所以我希望通過在meshmixer上扎實來掩蓋它. 但是, 一旦我點選這個選項, 整個檔案似乎變得"堵塞", 而且相當多的細節(像眼睛)似乎遺失了. 有甚麼可以做的事情可以讓薄殼堅固/厚度, 同時不丟失任何細節?

I got some model files the other day and they are huge. when I import into Meshmixer it crawls like molasses in freezing weather. Chitubox wont load it and Prusa slicer is really slow. Nettfabb wont allow it to upload because of the file size. I just want to hollow and add drain holes but Meshmixer does not like it and that's the only way I know how to reduce it.

Anyone have alternate suggestions? I know its not my computer, I opened multiple other files and no issues.

So I hollowed out a print on meshmixer, opened it in photon slicer and sliced it, well it printed with the base half off the plate, and I don't mean that it came off during printing, I mean for some reason it's printing the bottom of the base at an angle. I'll post some pictures of the print in the comments.

Here I have taken the same model, resliced it after adding some internal supports, and the slicing still shows the bottom working at an angle even after adding supports. The base of the mesh model is completely flat to the plate so I don't understand how this is happening.

I'm showing first and 5th layer so you can understand the way the base is creating itself. Mind you, the front of the base is what's printing last and the edge of the front doesn't start until the 9th layer

I don't know if its because I finally tuned things in right, or if its just because I switched models, but I'm FINALLY up and running!

First mini print was technically successful, it stuck to the build plate and went all the way through. Lost an arm and a tail due to bad supports, apparently, but at least it worked!

Re-oriented and re-did supports, crossing fingers for a perfect print this time! I'm at least hearing a nice rhythmic thumping of the FEP, so at least I know its sticking!

hello collective minds. Need some advice on 3d tools for prepping prints on my photon.
I'm working on an architectural print and some of the parts are only .05 thick, which isn't going to hold up while printing. I could go in an manually edit them but this would take 100s of hours I'm sure. Is there any tool, or method in the common tools (meshmixer, etc) that can auto scan the model and make any walls or planes double the thickness?

A very specific ask I'm sure, and I cant share the model due to legal limits but there's something similar to a fire escape (old style) and the metal plating is whats failing the most as it's only x thick and wont hold up to even a hair's worth of pressure when printing.

thanks in advance.

TL;DR - What program do you use to do your supports?

OK, so I've been printing for about 1.5 years now. Up until 3 days ago, my workflow has always been MeshMixer for mesh repairs or F360 for my designs, ChiTu for supports and slicing, validator for checking, print.

3 Days ago I had a look at PrusaSlicer for supports, then photon slicer for slicing, and I feel like I'm spending 1/4 the time doing supporting than I was in ChiTu.

I'm geniunely curious what method is most popular for supporting in the community, and if anyone has tried Prusa for supporting and then gone back to ChiToBox or Photon Slicer.

Thoughts brains trust?

Used Meshmixer to make sure it’s a printable solid. ✅
Used Chitubox to hollow and support ✅
Used Photon Validator to prevent islands ✅
But when I sliced with photon workshop I see these triangles that shouldn’t be there. Always have perfect prints, never had this happen to me before.
Thoughts?
maybe corrupt file?

使用meshmixer確保它是一個可列印的固體. 你知道嗎?
使用chitubox空洞並支援 ✅
使用光子驗證器防止島嶼 ✅
但是當我用光子車間切片時, 我看到這些不應該出現的三角形. 總是有完美的指紋, 以前從未發生過這種情況.
想法?
也許是腐敗的檔案?
