LimitState releases new STL file ‘auto fixer’ for 3D Printing files

LimitState:FIX users now have a choice of techniques for closing solids.

The latest version of LimitState:FIX has been unveiled, promising to be more robust and capable than before, with a host of under-the-hood enhancements and bug-fixes.

Utilising Polygonica technology from engineering software firm MachineWorks, LimitState:FIX aims to make the fixing of wall thicknesses, shell completion and noise removal with a single click.

Production companies and bureaux in particular find flawed STL files waste significant working time, so a ‘one click’ automatic fix, coupled with a sophisticated manual fixing processes is going to be a big draw.
“The software analyses and repairs holes in solids and fixes defective mesh files. It closes solids, fixes polygon orientation, removes self-intersections and noise shells, and ensures the geometry is manifold,” explains the press release.

New to this version is:
– The software now uses the new version 1.2 of the Polygonica engine to do its work. Importantly, this should mean that LimitState:FIX has enhanced automated healing of complex meshes
– Users now have a choice of techniques for closing solids. If the original fan closing technique does not give the right result, then the user can instead choose from: ‘planar’, ‘minimum area’ and ‘smooth’ closing techniques
– By default LimitState:FIX now uses four decimal place precision when outputting STL files, improving compatibility with other additive manufacturing software, such as Netfabb and Magics.
– ‘Noise Shell’ purging in the Auto Fix process has been enhanced, so the software now only removes very small, likely spurious, objects by default. Alternatively users can set the threshold for removing noise shells manually, as previously

A free demo of the software is available which fixes models but which does not allow files to be saved for subsequent printing, you can get it here.
The full software is priced at £2,999 per user for a perpetual license for bureaux and enterprises.

For small design and engineering firms and end users it is just £499 per user. However, customers purchasing the software before 30 April will benefit from reduced pricing – the Enterprise license is £2,099 and the Maker price is £399.
