3D Printing Melbourne: Mistakes to Avoid when Designing a 3D Model

Posted on July 27, 2018 in Printing

When it comes to 3D printing in Melbourne, no such thing as one-size-fits-all approach as the process itself can be very confusing. There are different kinds of software being used, print in various materials, and various printing technologies. This is why it’s no wonder that some people feel lost when designing a 3D model. Below are some mistakes that should be avoided if you want to turn your 3D model into a 3D print.


Avoid these Mistakes when Designing a 3D Model

1. Ignoring the Guidelines for Materials to be Used

Each printing material is unique. Some materials are strong or brittle, solid or flexible, rough or smooth, light or heavy, etc. This means that a single object needs to be ideally designed for a particular material. Your choice of printing material will determine the most basic design guidelines that should be followed.


2. Ignoring the Printing Technology

It is not only the chemical characteristic of the printing material that is different, but even the technology that is used in printing each one of them. One good example is interlocking parts. In materials such as Polyamice, ABS, or Alumide, it is possible to print interlocking-parts. But in Silver, Gold, or Bronze, it’s not possible. This happens not because of the material, but the technology utilized in printing the materials.


3. Ignoring the Wall Thickness

Any problem that is linked to the wall thickness is by far among one of the common reasons why there are some three-dimensional models that cannot be printed. There are some instances wherein the wall is too thin. These types of walls make very small parts on the model, making them not capable to be printed or tends to be fragile and will break off easily. There are some cases when very thick walls can generate a lot of internal stress which can cause it to crack and break.


4. Ignoring the File Resolution

When it comes to 3D printing, the commonly used file format is the STL or Standard Triangle Language. This means that the design would be translated into triangles. The majority of 3D modelling software offer the option to export the designs to STL file and set the necessary solution.


5. Ignoring the Software Guidelines

Today, there are various 3D modelling software packages that are available. Some of them were designed to create 3D prints while others are used by 3D artists and the designs often require additional editing before they can provide a printable 3D model.

3D printing is widely utilized in Melbourne and if you are one of the many who is benefiting from it, make sure that you avoid these mistakes. Doing so will help you maximize the use of the technology- making it a worthy investment.
