The capabilities and design constraints of 3D printing technology vary. As a result, while designing models for 3D printing, various factors must be taken into account to properly – print high-quality 3D parts in the 3d models marketplace.
Making high-quality 3D components starts with designing for 3D printing. Product designers should have sufficient experience creating 3D parts without jeopardising other factors such as aesthetics and performance.
Here are six crucial considerations when creating 3D components to help prepare and educate product designers. Continue reading to find out more.
Size
The size of your object is something to think about when making it from 3d models marketplace. Each technology has a preferred format; some are bigger, while others are smaller.
The FDM machine can print up to 16″ x 14″ x 16″ in size.

If your part is more massive than this, it can be sectioned before production and professionally bonded together.
The manufacturing time will be affected by the size of your parts. Large pieces take longer to construct and need more materials, resulting in elevated prices.
Overhangs
Any element of – the model supported by thin air will most likely fall when 3D printed. As a result, each layer should have some underlining material that may get designed.
Every printer has a maximum angle at which no support structures gets required. The estimated limit for FDM and SLA printers is 45 degrees. It’s tough to print a 3D model with an overhang – of more than 45 degrees. As a result, 3D designers should think about keeping the model’s overhangs to a minimum. Support structures can also get avoided in this fashion.

The Basepoint
The base condition is critical, especially to avoid warping. You might use Kapton Tape and Blue Tape to inspect the 3D printing area for scratches or tape-free regions. Similarly, if you’re using BuildTak, look for scratches and rips that might cause the base component to peel off in large prints or long periods.
If a glass foundation gets utilised directly, there should be no severe scratches or detachments that allow the component to tear off during 3D printing. A sticky spray gets recommended for 3D imprints on glass bases.
Purge the filaments
The filament purge is the final step that must get completed before 3D printing can begin.
The number of turns increased – and you make by replicating the Skirt before commencing 3D printing or increasing the number of turns you make by heating the extruder to the temperature – of the filament to be used and pressing it until the flow is continuous. The 3D printing application that gets utilised modifies this setting.
The material selection
There are several materials to choose from for your 3D print based on the method – you choose.
Typically, you decide – on the decision based on the limitations that apply to your component. It is critical to make your materials carefully if your part requires specific resistances.
It will get exposed to extremely high temperatures or chemical solvents – for example, ULTEM should be considered (in FDM technology). Polycarbonate is a suitable choice if impact resistance is required.
