Acquired some STL 3D printing information you wish to convert to the STEP format for CAD software program? We’ll present you easy methods to do it.
Not like conventional CAD software program, 3D modeling instruments like Blender and Maya aren’t designed to provide information for manufacturing. Easy plugins assist you to export STL information from software program like this, however exporting STEP information isn’t attainable with out a few extra steps.This text will take you thru the method of changing any STL file right into a STEP file, with steps to make sure that the tip result’s error-free.
Step 1: Exporting an STL From Blender
Blender can export STL information natively, making it splendid for many who wish to create fashions for 3D printing and CNC machining. Go to File > Export > Export as STL and select the file location and title you want to use. You’ll be able to select to export the Choice Solely if you wish to isolate a part of your Blender challenge.
Blender is free to obtain and use. Any model after Blender 2.8 will work for this information.
Step 2: Importing the STL Into FreeCAD
Subsequent, it’s time to import your new STL file into FreeCAD, which is likely one of the finest CAD applications. Go to File > Import and select the STL file you created within the earlier step. A mesh that resembles your 3D mannequin will seem on the display screen, providing you with the prospect to test for errors earlier than persevering with.
As its title suggests, FreeCAD is free to obtain and use.
Step 3: Repairing the Mannequin’s Mesh in FreeCAD
Some mesh issues are seen once you first load your file, however others gained’t be so apparent. FreeCAD comes outfitted with a set of research instruments that make it simple to make sure that your mesh mannequin is manifold and free from errors. Begin by choosing the Workbench dropdown menu and selecting Mesh Design.
Go to Meshes > Analyze > Consider and restore mesh to open the mesh restore software. You will note an All above exams collectively possibility on the backside of the listing. Choose Analyze and await the method to finish earlier than hitting the Restore button. It’s possible you’ll have to undergo this course of greater than as soon as to completely restore your mannequin, however there’s a probability your mannequin doesn’t want any repairs.
Step 4: Changing the STL Mesh Right into a Form in FreeCAD
An STL is simply an outer mesh, whereas a STEP file is a strong 3D object. Which means you want to convert your STL mesh right into a strong in FreeCAD, however this will solely be accomplished as soon as the mesh has turn out to be a form. Begin by going to the Half workbench, adopted by opening the Half dropdown menu and choosing Create form from mesh. A pop-up will seem so as to select an Overlap Tolerance; depart this at 0.10 and hit OK.
It can take a while to create your form if the mesh you’re utilizing is difficult.
Step 5: Changing the Form Right into a Strong in FreeCAD
Along with your form able to go, you possibly can create the strong you want in your STEP file. Choose the form you simply created within the Mannequin panel, adopted by going to Half > Convert to strong. This may create a brand new merchandise within the Mannequin panel with (Strong) subsequent to its title.
Step 6: Exporting the Strong as a CAD-Appropriate STEP File
It’s lastly time to create your STEP file! Go to File > Export and select the placement for the STEP file you make. Choose the Save as kind drop-down and scroll by means of the listing to search out STEP with colour earlier than hitting the Save button.
Utilizing a Transformed STL as a STEP File
STEP information can be utilized for quite a lot of CAD purposes. Many individuals don’t have their very own CNC machine or 3D printer, however you’ll find companies on-line that may flip your information into actual objects. The strategies mentioned on this article will work for any STL file, although complicated and detailed fashions will take extra time.
