Are you looking to make your 3D prints resistant to water exposure? Maybe you want to print a functioning part that will remain undamaged through wet environments? You are in the right place. Consider implementing our 5 easy solutions for waterproofing 3D prints. From choosing the right filament to post-processing techniques, you will learn practical strategies for keeping your objects dry and steady in the face of water.

Choose Water-Resistant Filaments

Waterproofing your 3D prints starts with choosing the suitable material. Many 3D-printed objects are printed with PLA (polylactic acid), which can absorb water and is prone to damage over time. Instead, opt for water-resistant filaments for 3D printing. For example, PETG (polyethylene terephthalate glycol) offers better water absorption resistance and can be easily printed on most printers.

Enhance Layer Adhesion

A strong bond between layers is crucial for creating waterproof 3D prints. You can enhance layer adhesion by adjusting the slicer settings of your 3D printer. Increase the layer height and extrusion width and use a higher temperature to improve the flow of melted filament. Moreover, you can experiment with slower printing speeds to ensure each layer has enough time to bond properly with the previous one.

Utilize Infill Patterns and Sealing Techniques

An insufficiently filled print can also lead to water seepage. Increase the infill percentage in your slicer settings to ensure there are no empty spaces or weak points within the print. Additionally, you can use special infill patterns. Gyroid and 3D honeycomb patterns are particularly useful for ensuring a high level of water resistance in your prints.

Apply Post-Processing Solutions (Coating or Varnish)

Applying a protective coating or varnish may also enhance the water resistance of your final product. Spray-on or brush-on waterproofing solutions can be used on the exterior surfaces of your 3D prints. The coating will form a barrier, shielding the object from water damage. Be sure to choose a coating specifically designed for your filament type to ensure compatibility.

Leverage Professional 3D Printing Services

If you are inexperienced in waterproofing 3D prints, using a professional 3D printing service might be advantageous. These companies can assist you in selecting the right material for your project and performing waterproof post-processing techniques. Utilizing their services may ultimately save you time and frustration in trial and error.

It is important to remember that there is no one-size-fits-all solution when it comes to making your prints waterproof. Each project is unique and may require combining these easy solutions for waterproofing 3D prints. With the right combination of techniques, you can ensure your prints are waterproof and ready for whatever you throw at them.
