Frequently asked questions

3DOptimizer is a unique software tool to optimize the main FFF printing settings (i.e. main slicing settings) for open-materials printers.

3DOptimizer is developed for everyone employing FFF printing on an everyday basis, e.g. for 3D printing filaments or 3D printers manufacturers, or service bureaus workers.

Finding the right printing settings is not easy. Two extreme situations exist at the moment: either printer manufacturers offer users a black box with predefined printing settings and a limited number of printing materials (closed printers), or printer manufacturers leave the users alone with dozens of printing settings and materials (open-materials printers).

Due to the multifactority of the printing process, one has to test many different combinations of slicing parameters. 3DOptimizer offers a way to make your testing process replicable and traceable by using a systematic testing framework. In 3DOptimizer you can test up to 28 different parameter combinations in a single print, and, thus, determine the optimal printing settings much faster.

To develop 3D-printer- and filament-specific optimized FFF printing settings in a standardized way.

Your printer should be able to execute G-code commands and it has to be calibrated.

It takes approximately four hours to arrive at the optimal, 3D-printer- and material-specific FFF printing settings — this depends on your printing speed, testing choices etc.

To perform all the tests you will need around 25 m of a filament (1.75 mm diameter).

You can optimize the first layer track height, first layer track width, nozzle temperature, printing speed, retraction distance, bridging parameters and many more.

Our proprietary algorithm generates adaptive (i.e. custom) G-codes to find the optimal FFF printing settings for your material and your 3D printer. Simply print the generated G-code, inspect it, and select the printing settings which work best. Test the parameters you want, and get a configuration file for you slicing software in the end.

No, we use a heuristic optimization method to arrive at the optimal printing settings — it means you select the best parameter combination from your test prints, and the software uses the selected parameter values to configure following tests.


The ultimate tensile stress of injection moulded sample is 41 MPa.

Obviously, 3DOptimizer cannot make materials printable against technical limitations (e.g. achievable nozzle or print bed temperatures).

3DOptimizer is not geometry specific, but it provides a good starting point for finding the optimal printing settings. A typical slicer software has around 100 parameters which you have to configure. Using our software you can determine and fix the most import slicing parameters. It might happen though that you will have to adjust some settings to be able to print a concrete geometry (e.g. cooling velocity, number of perimeters, or the type of infill or its percentage etc.)
