Is 3D printing for your project?
3D printing is a process with almost unlimited possibilities and you are only limited by your creativity. Nevertheless, it is advisable to consider your options particularly in the case of replication of off-the-shelf items or items with specific requirements.
First, what considerations will change whether you should have your item 3D printed or not?
-
Is it available as an off-the-shelf item? - The availability of an off-the-shelf item is a crucial consideration when deciding whether to use 3D printing. If a suitable, ready-made product exists and meets your requirements, it may be more practical and cost-effective to purchase it directly rather than opting for custom 3D printing.
-
Mechanical properties - will the parts meet the strength and durability requirements
-
Tolerance and Accuracy - super tight tolerances may require a different process like CNC machining. (Typically .2mm or .008" is an acceptable tolerance for most materials)
-
Surface Quality - printed objects have visible layer lines. Post processing can hide these. If this will not work for your project, selecting higher resolution or a different 3D printing process may be a better option.
-
Pricing - Several steps, including data processing, software setup, printer setup, material usage, and post-processing, influence the final price of each part.
Second, what main factors will play a role in pricing?
-
3D Design - design is charged by the hour
-
Size of the part - effects material use and print time
-
Material - material type is crucial for most applications
-
Quantity - as quantity goes up prices will go down
-
Complexity - geometry will change software and post model processing
