Olena modeled a detailed enclosure in Fusion 360. The geometry looked correct on screen but failed twice at the bureau. She needed someone to identify what the slicer couldn't tell her.
3D Model Preparation — Coryvane
Files that print
Most printing failures trace back to the model, not the printer. Coryvane works through each file individually — geometry, tolerances, wall thickness — before anything reaches a build plate.

What this takes 02
The work is iterative, not instant
Preparing a model for print isn't a single-pass operation. Depending on the geometry, one file can require several rounds of inspection, repair, and test-slice before the result is reliable.
Each engagement involves direct back-and-forth. Questions arise during the process, and answering them properly takes time on both sides.
- Expect at least one revision cycle per file
- Communication happens through the project, not just at the start
- Turnaround depends on file complexity, not a fixed schedule
- You'll receive a clear explanation of every change made
Practical outcomes
What the file looks like after
After the work is done, the model behaves predictably in a slicer. Geometry errors that caused failed prints are resolved at the source.
Watertight geometry No open edges, inverted normals, or non-manifold surfaces that cause slicer errors.
Print-ready tolerances Wall thickness and feature size adjusted for the target material and process.
Orientation guidance Recommended print orientation with reasoning, not just a default setting.
Who comes here
The situations that bring people to this
Taras inherited a STEP file from a supplier. The part needed reprinting with modified tolerances but the original had dozens of geometry issues that made editing unreliable.
Yaroslav had been printing simple objects for two years. A more complex figurine kept failing mid-print and he couldn't determine whether the problem was the model or the settings.
Before starting
This works when certain things are in place
Not every situation is a good fit. The process works best when the person on the other side understands what they're trying to print and can describe the problem clearly.
If the goal is still undefined — "make something printable" without a specific part in mind — the preparation work can't begin meaningfully.
- You have an existing file — STL, OBJ, STEP, or similar
- You know the target printer type or material
- You can describe what the print is supposed to do or fit
- You're available to answer questions during the process
- You understand that some geometry problems require redesign, not just repair
Range of work
Situations this covers
The work isn't limited to a single file type or problem category. These are the most common reasons files come in — each one different enough to require individual attention.
Mesh errors from export
CAD-to-mesh conversion introduces holes, duplicate faces, and inverted normals that aren't visible in the original software.
Thin walls and unsupported spans
Features that render correctly in a viewport collapse during printing because they fall below the minimum printable thickness for the process.
Assembly fit problems
Parts designed to fit together don't — because tolerances weren't adjusted for material shrinkage or the specific printer's dimensional accuracy.
Overly complex geometry
High-polygon meshes or Boolean operations that worked in the modeling tool create slicer slowdowns, artifacts, or outright failures at the printing stage.
The actual difference
Get in touch
Against the automated alternative
Online mesh repair tools exist and handle simple cases adequately. They run the same algorithm on every file and return a result without context.
The gap shows up with complex geometry — where the repair itself needs judgment about what the part is supposed to do.
1
Context-aware repair
Changes are made with the function of the part in mind. A wall isn't just thickened — it's thickened where load matters and left lighter where it doesn't.
2
Documented decisions
Every significant change comes with an explanation. If the file comes back with different geometry, you know exactly what changed and why the original wouldn't have printed reliably.
