FAQ: 3D Printing

About 3D Printing

What is 3D printing?

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.

How does 3D printing work?

It starts with the creation of a 3D model in your computer. This digital design is for instance a CAD (Computer Aided Design) file. A 3D model is either created from the ground up with 3D modeling software or based on data generated with a 3D scanner.

What is slicing software?

You need to slice a 3D model in order to make it 3D printable. Slicing is dividing a 3D model into hundreds or thousands of horizontal layers and is done with slicing software such as Cura, Simplify3D, Slic3r, etc

How does 3D printing work?

Printing 3D objects vary largely on the size of the print, the type of printer, and the shape of the objects. Printing can take anywhere from 9 minutes to 18+ hours to complete one object. Most completed prints are rarely ever ready to use right after printing. Post-processing usually requires some modifications (such as removing supports, polishing, painting prints) which are done manually. These modifications help to achieve the desired level of surface finish.

Materials

What materials can I use?

We provide 3 types of 3D printer (FDM, SLA, SLS) with different type of materials. See materials page for more details information.

Is it food safe?

Due to the nature of the 3D Printing process, most of our products are not food safe.

How are these products made?

Due to the nature of 3D printing, most of plastics are brittle and fragile, it cannot be used for engineering application.

Design Your Model

Which 3D software can I use in Mech Solutions?

You can use any 3D software that can export to our supported file formats: STL, OBJ, VRML2, X3D.

What software should I use if I’m a beginner in 3D design?

If you're just getting started, you may want to try awesome free software like Sketchup, Tinkercad or Blender, Wings 3D,etc.

What are the file formats supported by Mech Solutions for 3D printing?

For best results in your 3D printing, we suggest uploading in .STL or .OBJ format. But you can also upload a 3D file in any of the following formats: .3DM (Rhino), .3DS (3D Studio), .3MF, .AC3D, .ASE (3D Studio), .CATPART, .CATPRODUCT, .CGR (CATIA), .COB (TrueSpace), .DAE (Collada), .DXF (AutoCAD), .IAM / .IPT (Autodesk Inventor), .IGES / .IGS, .KMZ (Google Earth), .LWO (LightWave), .MD2/MD3 (Quake), .OFF, .PLY (Stanford), .PRC, .Q3O (Quick3D), .RAR, .SAT, .SCAD (OpenSCAD), .SKP (Sketchup), .SLDPRT, .SLDASM (SolidWorks), .STEP (ISO 10303), .TGZ, .U3D, .VRML, .X_T (Parasolid).

If you have more files, please zip it and send to us.

Do you provide 3D design service to fulfill my idea?

Yes, we do. Please go to design page to see more details.

Why do some designs require fixing before they can be made?

When you upload a design, we need to make sure the file is suitable for 3D printing, please read article: 3D Printing: Required Reading to see more details.

Where can I download the 3D model?

You can download 3d printed file from 3d printing marketplace, such as thingivers, youmagine, grabcad, The designs are free but you must respect the specific copyright attribution decided by the author.

How are prices calculated

The price depends on several criteria, including (but not limited to):

  • The physical quantity of material used for the end objects
  • The total quantity of material used during the manufacturing process (supports, offcuts)
  • Total machine time for the manufacturing process
  • Time spent in post-processing, quality control and packaging
  • The material and finish chosen

What can I do to save costs?

Costs vary widely by the material used, you can either try low cost materials, or use hollow rather than solid to decrease the printing price. Also, the cost may increase significantly if the dimensions increase.
