Frequently asked
Questions about Dexelize
Technical answers on what Dexelize does, the inputs it accepts, how it handles sharp edges, and the performance, GPU and memory characteristics you can expect. Dexelize is pre-launch — details here describe the current design and may evolve before release.
What is tri-dexel (triple-dexel) remeshing?
Tri-dexel remeshing is a voxel-based technique that rebuilds a surface
from depth samples taken along three orthogonal directions (X, Y and Z).
Instead of editing the original triangles, it samples where rays enter
and exit the solid, then extracts a fresh, watertight mesh from that
volumetric representation. This makes it robust to messy input
topology that defeats triangle-by-triangle repair.
What file formats does Dexelize accept?
Dexelize reads and writes STL on both input and output.
Models can be in any unit; the tool reads the file's declared units or
assumes millimetres. Additional CAD and mesh formats are on the roadmap.
What kind of input meshes does it work on?
Anything triangulated. Dexelize handles non-manifold inputs, open holes,
duplicated faces, folded facets, and inverted normals automatically — so
laser scans, photogrammetry output and broken legacy STL files are all
valid inputs. Clean CAD exports work too; they simply skip most of the
repair stages.
Does Dexelize preserve sharp edges?
Yes. Real convex feature edges are detected and preserved to
sub-millimetre fidelity, while curved regions are
smoothed faithfully without corrugation. Concave edges are left at the
voxel's natural rounding, which is a deliberate, geometry-safe choice
rather than an artefact.
Will the output import cleanly into CAD, CAM and CAE systems?
Output is designed to pass the strict defect checks that convergent-body
importers run — degenerate, folded, intersection, inconsistent-normal,
laminar-slit and open-boundary-edge checks. Every input is analysed
before remeshing and every output is verified before save, so what you
download is checked against the same rules the importer will
apply.
How large a mesh can it handle?
Multi-million-triangle inputs are routine. The practical ceiling depends
on available GPU memory; a typical workstation GPU comfortably handles
outputs into the high single-digit millions of triangles. Larger parts
can be processed at a coarser voxel size, since memory use scales with
the voxel grid resolution rather than the raw triangle
count.
How much GPU memory does Dexelize use?
Memory use is driven mainly by the voxel grid resolution, not by the
input triangle count. Finer voxel sizes on large parts use more memory;
coarser settings use less. Processing is chunked into tiles
so a part does not need to fit in GPU memory all at once — which keeps
memory bounded and lets large dies and mould blocks run on standard
workstation hardware.
How long does remeshing take?
Small parts typically complete in tens of seconds. Large dies and mould
blocks at production voxel sizes take from a few minutes to tens of
minutes depending on size and detail level. Coarser voxel sizes are
faster; finer sizes trade speed for detail.
Does Dexelize need an NVIDIA / CUDA GPU?
A CUDA-capable GPU is strongly recommended and is the default path,
because the tri-directional ray casting and surface extraction are
GPU-accelerated. A CPU-only fallback exists for
evaluation and for machines without a suitable GPU, but it is
considerably slower and is intended for trying the tool rather than
production throughput.
Can I run Dexelize without a dedicated graphics card?
Yes, via the CPU fallback, but with a significant speed penalty compared
with GPU processing. The CPU path produces the same geometry;
it simply takes much longer. For occasional small parts or evaluation it
is workable; for regular production use a CUDA-capable GPU is recommended.
Which operating systems are supported?
Dexelize targets Windows, Linux and macOS. GPU
acceleration depends on having a compatible CUDA-capable GPU; where one
is not available, the CPU fallback path is used.
Can I script Dexelize or run it in a batch pipeline?
Yes. Dexelize is built around a scriptable command-line
interface, so it can be driven from automation and batch
workflows — for example, processing a folder of STL files and writing the
cleaned results to an output folder.
Is my data uploaded anywhere?
The desktop edition processes everything locally;
nothing leaves the machine. Any hosted evaluation option processes files
on a server and deletes them after the job completes. If data handling is
critical to your workflow, the local desktop path keeps all geometry on
your own hardware.
Does Dexelize use AI or machine learning?
No. Dexelize is deterministic geometric processing, not
AI or machine learning. The same input and settings produce the same
output every time — a deliberate design choice for predictability and
repeatability in engineering workflows.
