The various 3D printing processes have their own capabilities and design restrictions. If you have been using a 3D printer Sydney for quite a long time now, then you should know the key design considerations to achieve the desired results. The specific design software that you are using when creating a 3D model does not really matter. If it is your first time in 3D modeling, there are a lot of great software that will help become familiar with 3D design.
Physical Vs. Digital
It is a must to keep in mind that when you design for 3D printing, your digital design will be the physical object. In a given digital design environment, there is no need to adhere to any laws of physics like gravity.
Every 3D printing process has limitations. Below are some of the most common design considerations that you need to keep in mind.
3D Printing: Design Considerations
All processes in 3D printing build the parts layer by layer. A material could not be deposited into thin air; thus, each layer should be printed over an underline material.
Overhangs are the areas of a model that can be partially supported by a layer below or can be unsupported. In each printer, there will be a limit on the angle that the printer can produce without needing for any support material. It would be best to limit the overhangs of your model.
Another thing that you have to keep in mind when using a 3D printer in Sydney to design a part is the thickness of the wall. Each printing process could produce accurate features that are thin up to a specific point. It would be best if you can add thickness to your model. Thickness that is greater than 0.8mm could be printed with all processes.
One thing that is usually overlooked when designing a three-dimensional model is that the materials being used for printing undergo physical change: they are sintered, melted, or scanned using a laser and then solidifies. The cooling and heating of material could cause the parts to warp.
Flat and large surfaces can be very prone to warping. But this can be avoided by the use of machine calibration and having enough surface adhesion between the print bed and your part.
Level of Detail
When making a 3D model using intricate details, it is a must to remember the minimum feature size of every printing process. The level of detail is then connected to the mechanics and capabilities of every printing process and to the chosen layer height. The materials and process used would have a great impact on the cost and speed of the print, thus determining whether the smaller details are necessary to the model is a significant design decision.
