Genius I.E. Emendo™ STL File Validation & Repair Software

Are your 3D prints coming out correctly?

It's easy for mistakes to creep into any CAD or scan file that cost you time and material!

Ensure a higher rate of success and save time and money with Avante Technology's Emendo STL Validation and Repair Software.


Identifying and Fixing Unseen Problems


The Emendo application provides users of all skill levels an automatic method of validating their 3D printing files prior to printing. Users can quickly check to see if their CAD file or scanned image is saved as a valid or “water-tight” STL file, and if not, automatically repair it.

STL files define the surface of the part to be printed. If there is a hole, or inconsistency in the surface(such as a “zero thickness wall), a 3D printer will have difficulty in printing the object as it was designed. Unlike 2D graphics files, 3D STL files can contain errors not easily seen or identified by the source application software.

Emendo provides the user with a 3D view of the file, highlighting the location and type of errors found in the file. This helps users learn how to design better CAD files, and also locates the cause of problems that require manual re-design before printing. Some 3D printing problems relate to the method of design used in third party CAD applications and require revision with that application.

Simple, Fail-Safe Process

Drag & drop a file to the 
Emendo application and it automatically checks and validates the STL file. If the file needs repair, a dialog box presents the user with the option to repair the file. When the user selects “repair”, Emendo automatically repairs the file, and presents the graphic display of the errors found by location and type. When the user saves the repaired file, they have the option to re-name it as a separate file or replace the original STL file with the repaired version.

Precise and Fast

A common problem in 3D printing has to do with tiny inaccuracies in the 3D model representing the object in the STL format. Each CAD or 3D scanner application software may output their mathematical construct of the 3D object in slightly different levels of precision. This is often due to the use of floating point calculations creating tiny rounding errors in the complex mathematical algorithms defining the object in 3D dimensions.

With potentially millions of 3D triangular facets representing the object, even very tiny rounding errors can add up to a big problem when the file is printed. Unlike most other mesh repair software; 
Emendo utilizes a unique, proprietary set of algorithms that makes repairs with the highest accuracy at relatively high speeds comparable with floating point calculations.

You will get a more accurate repair to the STL file without having to wait all day!
