• LimitState:FIX - Fixes the 3D models other tools can't!

    There’s nothing more frustrating than a 3D model that won’t print. Your 3D printing workflow grinds to a halt, costing you time and money. But you can fix almost all the problems in a 3D STL file in minutes with LimitState:FIX!

    It’s so simple - just look at the video to see how easy it is to fix problems:

    About LimitState:FIX:

    We’ve taken the incredible Polygonica technology, developed and proven over two decades, and embedded it in a super-easy-to-use product that automatically fixes 3D models. Your existing software will fix a few problems. But in our tests, LimitState:FIX fixes vastly more - saving you time, and letting you get back to designing and printing.

    Here’s how LimitState:FIX works. You’ve just built a fantastic STL model that looks perfect on-screen. But when it comes to printing, your printer won’t accept the file - or worse, takes time to print it, but it comes out wrong. Cue a frustrating cycle of fixing the model and trying to print. This is because preparing clean, watertight, STL files that will print properly on a 3D printer can be hard. Even experienced 3D modellers can leave defects in their model.

    Getting the model right can be painful. It often means boring, laborious manual fixing of your model. There are repair tools out there, but they aren’t always that reliable. This is why we developed LimitState:FIX.

    LimitState:FIX automatically identifies and repairs defects in STL files. And it does it fast. We used the groundbreaking Polygonica technology, which has set the standard for industrial 3D mesh modelling over the last 20 years. It’s consistently been the most robust tool for repairing meshes in industrial models. Now, finally, we've made the core mesh healing technology available to 3D modellers working in fields from product design, dentistry and jewelry to aviation and architecture to fix their models - fast. We think this is a real breakthrough which could make many 3D modellers’ lives much, much easier.

    Try the software now. Watch it analyse your model and fix the problems - though you won’t be able to print without the full license.

    Fixing operations:

    Auto fix

    Use the Auto fix function to automatically fix all the errors in a model.

    Close solids

    Many 3D print preparation tools rely on a solid being topologically closed. As part of the closing process in LimitState:FIX, other geometric problems are fixed. For example, duplicate geometry is removed and shells that are inside-out or orientated inconsistently with their neighbours are reversed. Get the best surface profile by choosing from a range of hole closing algorithms - including fan, planar, minimum area and smooth.

    Automatic merging of solids

    All intersecting or overlapping solids are automatically merged together to create a single, shrink-wrapped object that is ready for printing.

    Fix orientation

    Polygons in a 3D mesh should be ordered in an anticlockwise sense as viewed from the outside of the solid. LimitState:FIX will systematically identify and fix polygons in a mesh that are incorrectly oriented.

    Remove intersects

    LimitState:FIX checks if a objects are self-intersecting and fixes them if they are, while ensuring that the final geometry is as close as possible to the original.

    Remove noise shells

    Solids can contain small shells as well as the intended geometry. These are errors, and sometimes they are an artefact of the software used to create the solid. LimitState:FIX identifies these shells and removes them from the model. 

    Make manifold

    Many tools that deal with STL files require a manifold mesh in order for their algorithms to work correctly. LimitState:FIX will query whether a mesh is manifold and, if it isn’t, mend it.

    Other operations:

    Mesh simplification

    Often models contain many more polygons than they need to. This can make the file harder to manipulate than it needs to be and can stop it printing properly. LimitState:FIX cuts the number of polygons in a solid, while making sure it still looks right and has accurate geometry.
