If you would like to create accurate and quality 3D models for your 3D printing, there a number of things that you have to put in mind and implement. There is no one size fits all kind of approach. Each project has its set of requirements that should be followed.
Here is a list of mistakes that you should avoid for you to create a quality 3D print model.
Ignoring the material guidelines
The kind of material that you are going to use for the printing should inform the design of the model. There are brittle, solid, flexible, stiff, and light materials among other qualities. These materials include food material, organic material, metal, rubber, ceramic, and plastic among others.
When designing the model, you have to determine if the material will be able to stand the hanging walls, rounded services or can hold together as the printer comes up with the structure of the model. Ceramics may not do well on a hanging wall, but rubber or plastic would do. Certain food materials may not create a mixture that can hold together. Ignoring this would only lead to waste of time and material.
Ignoring the software guidelines
The market is awash with different 3D modelling software options. Novice designers can use some while others are meant for expert designers. It is important to ensure that you have read the guidelines for using given software before you start your model. It will save you the headache of having to redo the model or waste time looking for different functions when working on your model.
The most common software for people who are beginners in 3D printing is the free Mesh mixer. Tinkercad is great at creating hollow models. Have your software manual with you so that you can refer to it whenever you have problems.
Ignoring the 3D printing technology
There are different 3D printing technologies in the market. Some can handle some materials and not others. Each of the technologies has its weak points and strengths too. The common 3D printing technologies include stereolithography, Digital Light Process, Selective laser melting and selective laser sintering among others. It is important to know the technology that your printer uses along with its strengths and weak points. This helps you design models that will not only be accurate but also the best given the printing technology.
You cannot print interlocking materials with some of the printing technologies, especially where a supporting material is needed. Where you can do that, some materials can still not print interlocking parts.
Not taking notice of the file resolution
Most of the designers look at the printing technology, choose the material, and the software, but still take no notice of the file resolution and its format. If the file resolution is too low, you may have a pixelated print. (A print which looks smudged). On the other hand, if the file resolution is too high, it may take forever to upload the file
When it comes to the format of the file that you are printing, the most common format is the Standard Triangle Language. While you cannot change much on file in this format, some printers allow you to change the resolution of the file. However, most of the designers do not take heed of this feature and end up having problems with their files.
Ignoring wall thickness
The thickness of the wall plays an important part in the overall strength and quality of the printed piece. If the wall of the model is too thin and below the limits for the print, you will not be able to print the model with the printer. On the other hand, where the wall is too thick, the resulting product may become too thick that is cracks easily when pressure is applied.
A Proper balance needs to be kept when it comes to the thickness of the model. Otherwise, you will print a model that will not serve the purpose for which it was designed.
If you would like to have a good printed model, you need to know every bit of 3D printing beforehand. Take your time to establish the characteristics of the model, the printer technology, the material to use and the software options on the table. Everything should be done right for a high-quality model that is consistent with the reason for which it is printed. Otherwise, the whole process may just be a waste of resources and may lead to defective products.
