Repair of stl and scan data at the push of a button
With a new innovative function called "Marching Cube" the latest version of
CoreTechnologie's 3D printing software 4D_Additive, now repairs and simplifies
3D scan data and STL files into closed volumes, within shortes space of time.
Mömbris, 11.04.2022 (ab/mas) - The latest version of the 3D printing software
4D_Additive of the German-French software manufacturer CoreTechnologie has a
revolutionary tool to simplify tessellated files and turn them into closed solids in the
shortest possible time. The new feature allows any type of triangulated 3D model to be
automatically corrected and prepared for 3D printing.
Simplified 3D print preparation
Modern 3D printing is based on accurate CAD data but today more and more often on
data generated with a 3D scanner. The quality of STL data is often poor and not
suitable for 3D printing or other subsequent processes. To ensure error-free slicing
and printing, it is necessary to repair errors on STL models and send closed solid
models to the printer. In addition, scanned parts often have file sizes of several
gigabytes due to the high number of very small triangles. Especially if several scanned
files are to be printed in the same print job, the size of the data that must be sent to the
machine can become a real problem.
The 4D_Additive 1.4 software has revolutionary functions to close the tessellated
models into "watertight" solids and intelligently mesh reductin functions in ordert o
reduce the number of triangles without loosing accurracy. These new features called
„Marching Cube“ and „Mesh Simplification“ allow any type of triangulated, mostly STL
data, to be automatically corrected and simplified at the touch of a button.
Fast repair of scan data
With the innovative Marching Cube function, faulty STL models as well as scan data
can be repaired and transformed into closed solids practically at the push of a button.
The new function saves the user an extremely time-consuming manual repair. The
Marching Cube function combines a "voxelisation" of the parts with their repair,
whereby the size of the voxel, i.e. cube, and thus the fineness can be defined by the
user. After the adaptive filling of the part volume with voxels, the so-called
"voxilisation", a closed 3D mesh is generated. The 4D_Additive software thus repairs
models with hundreds and thousands of triangulation defects fully automatically within

a few seconds. In addition, the user has access to various options for the intelligent
reduction of triangles. By defining a maximum angle between the triangles, the
maximum chord deviation, by percentage reduction or by defining the desired number
of triangles the filesize and complexity of triangulated models can be reduced easily.
The use of the two new innovative functions makes it possible to repair any type of
scanned part without manual effort, thus creating printable solids with a reasonable file
size and resolution from scans and faulty STL models in a very short time. In the
future, this technology will certainly enable a significant simplification of the scanning
and printing process in many areas.
