Batch Export Script for OpenSCAD

Exports multiple STL files with optimized settings

For use with PrusaSlicer, Cura, or other slicers

Configuration

$ProjectName = “3D Print Batch” $ScadDirectory = Get-Location $OutputDirectory = Join-Path $ScadDirectory “_exports” $OpenSCADPath = “C:\Program Files\OpenSCAD\openscad.exe”

Ensure OpenSCAD exists

if (-Not (Test-Path $OpenSCADPath)) { Write-Host “Error: OpenSCAD not found at $OpenSCADPath” -ForegroundColor Red exit 1 }

Create output directory

New-Item -ItemType Directory -Path $OutputDirectory -Force | Out-Null Write-Host “Output directory: $OutputDirectory” -ForegroundColor Green

Find all SCAD files

$ScadFiles = Get-ChildItem -Path $ScadDirectory -Filter “*.scad” -File | Sort-Object Name Write-Host “Found $($ScadFiles.Count) SCAD files`n” -ForegroundColor Green

$SuccessCount = 0 $FailCount = 0

Process each SCAD file

foreach ($ScadFile in $ScadFiles) { $OutputFile = Join-Path $OutputDirectory “$($ScadFile.BaseName).stl” $ScadPath = $ScadFile.FullName

Write-Host -NoNewline "Exporting: $($ScadFile.Name) ... "

try {
    # Call OpenSCAD with headless rendering
    & $OpenSCADPath -o $OutputFile $ScadPath 2>$null
    
    if (Test-Path $OutputFile) {
        $Size = (Get-Item $OutputFile).Length / 1MB
        Write-Host "✓ Success ($([Math]::Round($Size, 2)) MB)" -ForegroundColor Green
        $SuccessCount++
    } else {
        Write-Host "✗ Failed" -ForegroundColor Red
        $FailCount++
    }
}
catch {
    Write-Host "✗ Error: $_" -ForegroundColor Red
    $FailCount++
}

}

Summary

Write-Host “n==========================================" Write-Host "Export Summary:" -ForegroundColor Cyan Write-Host " Successful: $SuccessCount" -ForegroundColor Green if ($FailCount -gt 0) { Write-Host " Failed: $FailCount" -ForegroundColor Red } Write-Host "nFiles ready in: $OutputDirectory” -ForegroundColor Yellow

Optional: Open output directory in Windows Explorer

$Choice = Read-Host “Open output folder? (Y/n)” if ($Choice -ne ‘n’ -and $Choice -ne ‘N’) { explorer.exe $OutputDirectory }
