3Data Expert Free - Free STL repair, AM production communication and report generation

3Data Expert Free STL Editor GUI

DeskArtes 3Data Expert Free allows you to work with faceted data, like STL, VRML and 3MF. Free viewing, repair and STL file output will provide you with entry level functions for succesfull 3D Printing and AM without any cost. Get the best free STL Editor for hobbyists and DIY today!

Optionally, you can purchase more advanced production documentation and reporting functions for AM production reporting and quality control. Also, different 3D CAD Import Translators to triangulate and auto-repair standard and native 3D CAD models for 3D Color Printing, Additive Manufacturing and Simulation applications. Import translators include STEP, CATIA 4/5/6, CATIA CGR, NX Unigraphics, SolidWorks, Solid Edge, Inventor, JT and Creo/ProE input formats. Conversion keeps original assembly colors (not textures) for 3D Color Printing and can generate optimized triangulation for simulation applications. Color models can be reliably transferred to 3D Color Printing preparation software modules 3Data Expert Color or 3Data Expert Base via DeskArtes native file formats .3de and .3dez.

3Data Expert Free is supported on Windows XP / Vista / 7 / 8 / 8.1 / 10 / 11.

3Data Expert Free - free and easy 3D CAD viewing, checking and repair

3Data Expert Free is entry level tool targeted for viewing, verifying, repairing, dimensioning and communicating 3D geometry information. 3Data Expert Free allows you to input triangle models, create consistent topology, check errors, repair normals, stitch and fill gaps as well as output STL data for 3D printing without any cost.

Save time by validating your 3D model data

3Data Expert Free is a software tool for CAD designers who want to provide perfect solid data to downstream applications. Import STL models or optionally surface models into 3Data Expert Free. Locate costly errors and correct them using your own CAD system. Verify the integrity of the data before sending it to AM, 3D Printig, CNC or CAE systems. Finally, build documentation can be generated for production monitoring, PDM and quality control.

Generate AM production reports

Optionally, 3Data Expert Free includes new commands to produce documentation for the AM print jobs. An overall Production Screenshot can be used to identify parts on the build area and Generate Report command provides detailed information on each part in the build area.

Additive Manfuacturing report
  • Produce build platform image with parts and labels for part identification.
  • Generate report with detailed part data for quality control and PDM.
  • Produce both .doc and .xml files with direct links to part properties.
  • Report model name, total volume, area, vertical area, etc. for cost calculation.
  • Output detailed data for each object: bounding box, number of triangles, ...

View, verify and communicate faceted 3D models

3Data Expert Free can input and output all relevant faceted 3D file formats for Additive Manufacturing. Automatic model verification, measuring and clipping commands help you to easily decide if the model can be printed or not.

STL Clipped and Wall Thickness
  • Input various faceted models: STL, 3MF, VRML, ZPR, OBJ, DXF, PLY, 3DS, Collada, FBX and proprietary 3DE Files.
  • Output following faceted models: STL, 3MF, VRML, ZPR, DXF, PLY and 3DE Files.
  • Automatically orient triangle normal direction for correct 3D Printing.
  • Viewing with rotate, pan, zoom and clipping commands, real-time slices for internal geometry checking.
  • Measuring with distance, radius, angle, wall thickness and 2D Drawings commands.
  • Export bounding box, area and volume for build time estimation.

Upgrade to professional STL repair tools.

Expert Series product suite offers a modular path to full STL file repair and manipulation. Start from model repair and basic splitting and mark ups with Dimensions Expert or 3Data Expert Lite, and when necessary, continue to full model manipulation with 3Data Expert offset, hollow, drain hole and support commands. All DeskArtes products offer state-of-the-art model preparation functionality with reasonable prices. New 64 bit implementation allows the handlng of the largest and most complex 3D models for Additive Manufacturing, Simulation and 3D Printing.
