How to make an Enclosure by 3D Printing

SLA 3D printing offers a variety of engineering materials that can be used to create accurate 3D printed parts and prototypes, helping you reduce costs, iterate faster, and bring a better experience to market.
With 3D software and a 3D printer, we can create a custom 3D printed enclosure part with snap-fits in following easy 2 steps. Snap-fit joints are a quick and easy way of connecting two 3D printed components together using interlocking features. Not only are they a low-cost, time-saving way to connect, but they also reduce the number of parts in an assembly, making it possible for quick assembly and disassembly.

Step 1: Prepare and check the Enclosure Desig

For this project, we are going to make a enclosure for the inside of the cooling module to check if the client's design is incomplete.

Step 2: 3D printing the whole Enclosure

3D printed enclosure with snap-fits don't have injection molding design limitations (draft angles, separation lines, wall thickness, undercuts etc.) and can be easily designed and altered. This makes them ideal for rapid prototype generation where clearance and fit are critical. This is why they’re often applied in the design and testing of enclosures.

The SLA and SLS 3D printers are very accurate, so you can tighten the tolerances to 0.2 mm without much risk.

Desktop FDM 3D printers can warp your design and lift it off the board, so you should allow a larger tolerance of 1.5-2 mm to ensure that the cooling module can be installed internally even if the walls are somewhat warped.
As you can see from the picture above, these are the parts that were printed out.

After the inspection is correct, the parts can be assembled.
