Preparing Your 3D Files
After obtaining a 3D model, the next step is preparing your files for printing with a slicer. STL (stereolithography) files, representing a triangulated CAD model, are the most commonly used in 3D printing. Other files for 3D printing include .step, .3mf, and .obj.
The quality of your STL file dramatically impacts the final printed object, so proper preparation is crucial.
Ensuring an STL is ‘watertight’-without holes or gaps-is a key aspect of preparation. Software like meshmixer can help you verify and correct surface issues in your STL files. This is vital because imperfections can cause issues during printing, leading to flawed objects.
Maintaining a balance between file size and surface smoothness is also important. Larger, detailed files can be challenging to process, so finding a middle ground ensures quality and efficiency. Different CAD programs offer unique settings for exporting STL files, affecting their readiness for 3D printing. Understanding these settings are choosing the right material and layer height ensures a successful print job.
One downside to STL files is that they don’t store units in them. It’s assumed that you are designing in mm even if the designer is using inches. This is why the model can be really small when its pulled into the slicer. The slicer will usually notice that the model was designed in inches and ask if you want it converted for you, but it doesn’t always catch this.
A way around this problem is to use a 3MF file instead. This file type has all the function of an STL file but also stores more data like the file units, who the designer was, and it’ll even store printer settings. When using a 3MF file, you’ll know that the object on the back end will come out at the correct dimensions.
Just recently, the STEP file became compatible with all slicers. This was a total game changer since you had to convert over the file beforehand to manufacture it. Also, unlike STL and 3MF files, STEP files can be edited in 3D modeling programs such as Plasticity or Fusion 360. This allows the 3D printing shop to edit files for the customer. Say if a hole dimension is wrong or a slot needs larger bumpers.
Submitting Your Print Job
Once your 3D files are ready, submit your print job. Requirements for submitting print jobs can vary, but generally, your 3D object must conform to specified standards.
Typically, to submit a print job, you make a request on this service’s platform. This straightforward process involves going to the Order Now page, add your information, then fill in the material, color, and infill. If everything goes right, you should see an Order Submitted page.
From here, someone will contact you within 25 hours. If the parts are printable and the information is complete, you’ll get back a quote. Otherwise, you’ll get a few questions to clear up any confusion. If the quote looks good, then confirm that you want to start with production.
Monitoring and Managing Print Jobs
After submitting your print job, you can always check on the status by emailing into our service. We can confirm that we are on track with the lead time and even send you some pictures to show how it’s going.

This centralized control simplifies handling multiple print jobs simultaneously, especially in busy environments. Live video feeds in remote monitoring tools provide real-time visibility of the printing process, helping you catch issues early.
Furthermore, some advanced software solutions, such as PrusaConnect, OctoPrint and Obico, offer remote control capabilities for various 3D printer models. These tools send notifications about your print job status such as completion or errors, keeping you informed. Using these remote access features reduces downtime and allows you to promptly address potential problems, even from afar.
Post-Processing Your Printed Objects
Once your print job is complete, post-processing is often needed to achieve the desired finish. Sanding is a common method to smooth the surface of the 3D printed objects, especially those made with FDM materials. Starting with low-grit sandpaper and progressing to higher grits ensures a more refined finish.
Acetone smoothing is highly effective for ABS material prints. This process uses acetone to melt the surface layer, reducing visible layer lines and smoothing the object. These techniques can significantly enhance the aesthetic and functional qualities of your printed objects.
Proper post-processing improves not only the look but also the durability and usability of your printed objects. Whether preparing a model for display or a functional part for a project, proper finishing ensures they meet your expectations and serve their purpose.
Picking Up Your Completed Prints
When picking up your completed prints, follow a few important steps. First, check your printed object for imperfections or defects to ensure quality meets your standards. By the time you pick it up, print should be cooled down to room temperature. Residual heat can affect the structural integrity of the print.
Handle your printed objects with care, as they can be delicate and may require gentle support during transport. For intricate details, consider using protective wrapping to keep prints intact during transit. Proper handling and transportation are essential to preserve print quality.
After picking up your prints, proper storage is key to maintaining their condition. Store tham in a clean, dry area away from direct sunlight to prevent deterioration. Following these steps ensures your completed prints remain in excellent condition and are ready for use.
