When you’re working with 3D mannequin design and printing, you’ve doubtless encountered confusion with two widespread file varieties—STEP and STL. .
STEP recordsdata are the format used to attract and design your 3D fashions, whereas STL recordsdata are the format essential for 3D printing. Subsequently, understanding the method of changing STEP to STL is important to producing a high-quality 3D-printed product.
This information for STEP-to-STL conversion will dive deeper into STEP and STL file codecs; we’ll additionally present a step-by-step breakdown to comply with when you might want to convert your STEP file to STL and again once more. Lastly, we’ll provide recommendations on bettering file conversion high quality so you may get optimum outcomes with 3D printing.
What Are STEP and STL File Codecs?
When working with 3D fashions, selecting the best file codecs and settings is essential. On initiatives involving a number of professionals, chances are you’ll encounter a scenario the place you’re requested to ship a selected file sort. Being ready to ship the suitable file format is essential to retaining your undertaking on monitor.
Two of the commonest file codecs in 3D printing are STEP (normal for the change of product information) and STL (normal triangulation language). Distinguishing between these two codecs and understanding when to make use of them is important to operating profitable 3D programs.

Evaluate STEP and STL recordsdata:
- STL recordsdata: STL recordsdata are particular file varieties utilized in 3D printing programs. Reasonably than containing the total CAD mannequin information, STL recordsdata solely include the mannequin’s surface-level element, that is essential for 3D printing.
For that reason, STL recordsdata and different non-STEP recordsdata are thought-about “mesh” recordsdata. STL is the commonest mesh sort file, however others embody PLY and OBJ.
Whether or not you ship or obtain STEP recordsdata, understanding tips on how to convert them into STL recordsdata and vice versa is a vital ability that may maximize efficiencies in the course of the 3D printing course of.

Learn how to Convert STEP Information to STL
Since STL recordsdata can’t be simply manipulated utilizing CAD packages, the traditional course of is to begin off with a mannequin in STEP format and convert it to STL when it’s prepared for printing. Realizing tips on how to convert file varieties is handy for sustaining this workflow.
When you’re working with a mannequin in CAD and need to get it 3D-print prepared, comply with the beneath steps for STEP-to-STL conversion.
1. Select a STEP-to-STL Converter Program
To transform your STEP file, start by choosing this system you’ll use to transform your recordsdata.
Common STEP file converter choices embody:
- CAD packages: When you’ve acquired a accomplished STEP file, the excellent news is that you just’re already working in a CAD program that has conversion capabilities.
Whether or not it’s SolidWorks, Fusion360, or one other CAD software program possibility, the method might be comparatively comparable. Discover this system’s file exporter possibility and choose “STL” as an out there file format. Alternatively, you should use the “Save As” operate to avoid wasting the STEP file as an STL.
- OnShape: Another choice to acquainted CAD packages is OnShape, which is a cloud-based CAD instrument with a free model. The offline model lets you privately convert your STEP recordsdata to STL without cost.
Merely add and open your STEP file in OnShape, right-click the viewport, and choose “Export.” Choose the STL file format and wait till the transformed file sort is prepared for obtain. Relying on the file dimension and complexity, this may take just a few seconds to a number of minutes.
Free STEP or STL on-line converters: Within the occasion that you just don’t have entry to a CAD program otherwise you not have a license, you should use a free or low-cost on-line converter to get the file sort you want. This selection saves you the trouble of downloading software program, and you should use it from any cell machine.
Some on-line file converter choices with free variations are ConvertCADFiles, CAD Exchanger, and MakeXYZ. Every program additionally offers the choice of changing recordsdata from STL to STEP or changing STL recordsdata to a number of different codecs.

2. Do Essential Mesh Restore
One of many principal challenges of changing fashions from STEP to STL is that you just lose a few of your actual geometry as soon as in STL. Cleansing up your newly transformed STEP file ensures you get the optimum mannequin for 3D printing.
The method of cleansing up your STL file mannequin is called mesh restore. Meshing refers back to the triangles that seem within the STL format which are translated from the unique CAD design. The extra triangles that cowl the mannequin’s floor, the finer the mesh and the clearer the options.
On account of limits in interoperability when transferring your file from CAD to your 3D printing program, you might want to make sure you’ve set adequate sufficient triangles to maintain the mannequin clean.
Earlier than you convert the form to STL, it should at all times seem clean in CAD. Nonetheless, you may’t assume that your created form will translate immediately as soon as in STL format.
Earlier than changing your STEP file, choose the suitable decision settings in CAD—both coarse, effective, or further effective. The best decision ensures the mesh masking your mannequin floor is as clean as potential. File smoothing packages, like Blender, also can enable you to restore mesh in your STL file to make the form as clean or faceted as wanted.
3. Know Learn how to Convert STL to STEP
Now that you just perceive the STEP-to-STL conversion course of, chances are you’ll be questioning the reverse—tips on how to convert STL to STEP. One possibility, you should use the identical on-line conversion packages as an STL-to-STEP converter.
Changing STL to STEP lets you return and make modifications to the unique STEP file mannequin earlier than printing.
If you might want to make changes to your STL file in CAD, you may import your STL file into SolidWorks or Fusion360 and edit it there. This lets you make exact modifications whereas sustaining model management.
Learn how to Enhance Conversion High quality When Changing a File From STEP to STL
To enhance the standard of your transformed STEP file, you not solely want to pick out the suitable decision settings, however you additionally want to make sure the file dimension doesn’t find yourself too giant to work with.
In case your CAD software program lets you manually alter attributes like chord peak or tolerance, deviations, and angular tolerance, this can be the very best strategy. Hold adjusting these parameters till you get the best element potential with out your file exceeding 20 MB. Proceed refining these settings till your mannequin has as few flat spots as tolerable.
