It is known that in 3d printing technology, no one size fits every approach. With the use of various software, print in various materials, and not different printers but also various printing technologies are used. So sometimes you might feel lost and it can sometimes appear difficult to make a perfect 3D model for 3D printing.
5 mistakes to avoid with 3D printing designs
1. Ignore material guidelines
Every 3D printing material are different. Some could be brittle, and some are strong. A few, flexible or solid, smooth or rough, and so on. Also, an object must be ideally designed for a specific material. The choice of printing material issued to decide some basic design guidelines you need to stick to.
Each 3D printing material is different. So you have to read the design manual to use the material of your choice.
2. Ignore print technology
Not only the chemical properties of the print material is different, but also the technologies used in printing.
E.g. inter-locking parts like ABS, Polyamide, Alumide, you can print interlocking parts, while in others like Gold, Silver, Bronze, or Resin that cannot be done. The reason is that the technology used in printing is different.
3. Ignore wall thickness
You can get information about wall thickness in the guidelines which are mentioned, it’s essential to focus here as well.
In certain cases, the wall thickness is too thin. Too thin walls make small parts on the model, unable to be printed or very delicate and could break easily. On contrary thick walls, generate too much of internal stress and make the item break.
Getting the right amount of thickness is essential.
4. Ignore file resolution
For 3D printing files, the common file format is STL, which says that your design will be transformed into triangles in a 3D space. Many 3D modeling software can export your designs to an STL file and get the desired resolution.
To make a choice of the right resolution for your file is essential for good quality print.
Resolutions which are too low or too high can lead to problems:
Low-resolution STL file: This will cause poor-quality print. The triangles in your STL file would be big and the surface won’t be smooth. You will get a “pixelated” print.
Very high-resolution STL file: The file will be too big and sometimes you can’t handle it.
5. Ignore software guidelines
If you apply beginner-friendly software which was solely produced for 3D Printing (e.g. Tinkercad), you might face trouble in creating hollow models.
With software like Blender, SketchUp, or ZBrush, some further file preparation would be needed. It is completely based on which software you are using, shells might need to be joined together, models might need to be watertight, wall thicknesses need to be applied, and printing sizes must be set.
You need not be a worry. Things are not that bad as you might be considering. Be sure about your software and material of choice.
