3-Dimensional printing is the process of creating a 3D object by systematically layering thin material to build it. A 3D printer reads digital data from the computer, which commands the various layers to make an object. 3D printing is beneficial to businesses that want to customize large quantities of products according to specific needs and requirements.
There are three crucial elements to consider: a 3D printer, slicing software, and filament.
The filament is the material, and your choice of which material is most applicable will depend on durability, heat resistance, and malleability. Most beginners use PLA filament because it is easy to print and cost-effective. Printing uses CAD and slicing software, with the former being commonly used to create personalized models. Slicing software effectively decodes STL to data or a language the printer can understand.
Colors
It would be best if you considered the outer appearance of the 3D printed model. For beginners, it is advisable to choose from the primary colors. If you have a precise color in mind, check from different sources like books and the internet.
Tolerance
Tolerance is how each part of the model fits together to create one single piece. Beginners should ensure that there is enough space between layers for patience. One area where tolerance plays a critical role is in designing joints and moving parts. There are no support structures for the model in such cases, but the socket and ball features must rotate. As a beginner, tolerance is a must-know concept.
Maximum size
A common mistake done by beginners is to vary the size of an object when printing. For best output, the item should be printed in actual size. If the model is bigger than your 3D printer, break down the printable model instead of resizing it. The smaller pieces are then printed in a separate batch that can be scaled to fit.
Overhang
Overhangs are geometrical shapes on your model that help to extend your 3D object. It is advisable not to have too many overhangs because they ultimately affect the item. For beginners, ensure your model is simple and easy to print. For a successful 3D printing work, ensure you consider your printing material, needs, and size.
Bridging
It would be best if you were conversant with the concept of bridging, which means your printer can print between two points that have no connections whatsoever. The more spaces your bridge has, the more pitfalls it will have during the printing process. The best way to avoid pitfalls is to print objects in an upright position.
Supports
Always use dissolvable support materials as a solution to bridging. Supports prevent part deformation and ensure all the parts are attached to the main body. If you wish to print without support, provide the angles in your object are below 45 degrees.
Polygons
Get a comparison of the high and low resolution of your 3D printer from a reputable manufacturer, such as Konica Minolta. Polygons ensure your design are both efficient and straightforward. Beginners can use standard polygon models because they allow you to create familiar objects.
Infill
Infill is the percentage of material that occupies the internal part of a 3D object. Beginners are advised to use the rectangular infill offers strength in all directions and easy to make layers on top of each other.
