One of the most versatile and commonly used materials in the world is plastic. It’s strong, durable, and weather resistant, making it perfect for a wide range of applications. But one downside of plastic is that it isn’t waterproof.
If you need to make something out of plastic that needs to be waterproof, there are a few things you can do.
- PLA is a water-soluble plastic, so it will dissolve in water if left uncoated
- To make PLA waterproof, you need to coat it with a water-resistant finish
- One way to do this is to brush on a thin layer of clear nail polish or lacquer
- Another option is to spray on a clear acrylic sealer like Mod Podge Outdoor
- Let the coating dry completely before submerging the PLA in water
Can You Make Pla Waterproof?
PLA, or Polylactic Acid, is a biodegradable and environmentally friendly plastic derived from renewable resources like corn starch. While its properties make it ideal for many applications, one downside is that it is not naturally waterproof.
There are however, a few ways to make PLA more water resistant.
One method is to coat it with a thin layer of acrylic varnish or resin. This will provide a barrier against moisture but will also slightly alter the appearance of the PLA. Another way to waterproof PLA is by laminating it with another material like PVA (polyvinyl alcohol) which is naturally waterproof.
This will protect yourPLA object from getting damaged by water but again will change its appearance. If you need your PLA object to be both strong and waterproof, you could try 3D printing it with Fusion 360’s ‘HydroFill’ setting enabled. This uses PVA as support material which dissolves in water, leaving behind a fully watertight object.
The trade-off is that objects printed this way can take significantly longer to print. So while there’s no guaranteed way to make PLA 100% waterproof, there are definitely some methods you can use to give it increased resistance to moisture damage.
How Do You Protect Pla from Moisture?
PLA, or Polylactic Acid, is a thermoplastic polymer that is derived from renewable resources like corn starch or sugar cane. PLA is biodegradable and has a lower carbon footprint than other plastics. However, PLA is also hydrophilic, meaning it absorbs water easily.
This can cause problems when printing with PLA, as the moisture can cause the filament to clump and jam in the extruder. There are a few things you can do to protect your PLA filament from moisture. First, you can store your filament in an airtight container with desiccant packets.
These packets will absorb any moisture in the container and keep your filament dry. You can also try sealing your spool of filament in a zip-top bag before putting it in the container. Another way to protect your PLA filament from moisture is to use a heated build chamber for your 3D printer.
This will help to keep the humidity level low inside the printer and prevent any moisture from getting to your filament. If you don’t have a heated build chamber, you can try placing a small fan inside your printer to circulate the air and keep the humidity low. Finally, if you live in a particularly humid environment, you may want to consider using ABS instead of PLA for your 3D printing projects.
ABS is more resistant to moisture absorption than PLA and won’t be affected by high humidity levels like PLA will be.
How Do You Make a 3D Print Watertight?
In order to make a 3D print watertight, you need to use a material that is not porous. Some materials that can be used for this purpose are ABS plastic, polycarbonate, or PETG. You will also need to use a sealing agent such as XTC-3D or Smooth-On Epoxy.
Once you have your material and sealing agent, the first step is to clean the surface of your 3D print. This ensures that there is no dirt or debris that could prevent the sealant from adhering properly. Next, apply the sealing agent evenly over the surface of the 3D print.
Be sure to follow the instructions on the packaging of your chosen product in order to ensure best results. Once dry, your 3D print should now be watertight!
Is Pla Waterproof After Printing?
No, PLA is not waterproof after printing. While it is possible to print with PLA on a water-soluble support material like PVA, the printed object itself will not be waterproof.

Pla Waterproof Spray
When it comes to choosing a waterproof spray for your gear, there are a lot of options out there. But if you’re looking for something that’s both effective and environmentally friendly, then PLA Waterproof Spray is the way to go.
PLA, or polylactic acid, is a biodegradable plastic made from renewable resources like corn starch or sugar cane.
And because it’s biodegradable, it won’t pollute the environment like some other waterproofing sprays out there. But just because PLA is good for the environment doesn’t mean it’s not tough on water. In fact, this spray has been tested and proven to be completely waterproof in both fresh and salt water.
So whether you’re spraying down your gear before a hike in the rainforest or gearing up for a day of sailing, PLA Waterproof Spray will keep your belongings dry and protected.
Water-Resistant 3D Printing Filament
Water-resistant 3D printing filament is a type of filament that is designed to be resistant to water. This means that it will not absorb water from the environment and will not swell or shrink when exposed to water. Water-resistant filaments are ideal for applications where moisture or humidity is a concern, such as in food storage or medical devices.
Water-resistant filaments are typically made from materials like polyethylene terephthalate (PET), which is the same material used to make soda bottles. PET is a strong and durable plastic that can withstand high temperatures and pressures. It also has excellent resistance to chemicals and solvents.
Other common materials used for water-resistant 3D printing filaments include nylon and polycarbonate (PC). Nylon is another strong and durable plastic, but it has even better resistance to moisture than PET. Nylon can also be dyed easily, so it’s available in a wide range of colors.
PC is similar to nylon in terms of strength and durability, but it’s less flexible. However, PC does have good chemical resistance and can be transparent. There are several factors to consider when choosing a water-resistant 3D printing filament.
The most important factor is the intended use of the print; different applications will require different levels of water resistance. For example, prints that will come into contact with food or skin need to be more resistant than those that will only be exposed to air or water vapor. Additionally, the level of detail needed in the print may dictate the required degree of water resistance; highly detailed prints may require a more robust filament while simpler designs can get by with a less expensive option.
Ultimately, it’s important to select a filament that meets the specific needs of your application.
Is Petg Waterproof
Is PETG waterproof? This is a common question we get at eSUN, and the answer is… it depends.
PETG by itself is not waterproof, but it can be made water-resistant with the addition of a few simple ingredients.
The most common way to make PETG waterproof is to add a thin layer of PVA (polyvinyl alcohol) to the surface. PVA is a clear, odorless, and non-toxic polymer that is often used as an adhesive or sealant. When applied to PETG, it forms a barrier that repels water and protects against moisture damage.
To make your own waterproof PETG, start by cleaning the surface of the material with alcohol or acetone. Next, apply a thin layer of PVA using a brush or spray bottle. Allow the PVA to dry completely before exposing the material to water.
If you need even more protection from moisture, you can apply a second coat of PVA or seal the surface with another clear coating like epoxy resin or polyurethane varnish. With proper care, your newly waterproofed PETG should last for years to come!
Cura Watertight Settings
The default settings for Cura are not necessarily the best for every model. In this post, we’ll show you how to change your watertight settings in Cura to get the best results for your 3D prints.
The first setting to consider is infill.
Infill is the percentage of the interior of your model that will be filled with material. A higher infill percentage will make your model stronger and more watertight, but it will also use more material and take longer to print. The default infill setting in Cura is 20%, but you may want to increase this to 50% or more for a watertight print.
Another important setting is wall thickness. Your walls should be at least 2mm thick for a watertight print, but 3mm or more is even better. You can adjust this setting in Cura by going to “File > Preferences > Printing.”
From there, you can enter a new value for “Default wall thickness.” Once you’ve got your infill and wall thickness sorted out, it’s time to move on to supports. Supports are essential for printing complex models, but they can also add weakness points to your print if they’re not properly removed.
For watertight prints, we recommend using tree supports instead of the traditional grid supports. Tree supports are easier to remove and leave fewer places for leaks. You can enable tree supports in Cura by going to “File > Preferences > Printing” and checking the “Use tree support” box under “Support type.”
Finally, you’ll need to choose the right material settings for your printer. ABS plastic is a good choice for water-resistant prints, but PLA will work in a pinch too. Be sure to consult your printer’s manual before making any changes to these settings.
With these four simple tweaks, you can make any model much more watertight when printing with Cura!
There are many reasons you might want to make your PLA plastic waterproof. Perhaps you’re printing objects that will be used outdoors and need to withstand the elements, or maybe you want to print something that will be submerged in water. Whatever the reason, there are a few different methods you can use to make your PLA prints waterproof.
One method is to use a clear coating designed for plastics. This can be sprayed on or brushed on, and will provide a durable layer of protection against water damage. You can also try sealing your PLA prints with varnish or shellac.
These materials have been used for centuries to protect wood from moisture, and they’ll work just as well on plastic. Finally, if you’re really looking for a tough waterproof finish, try using epoxy resin. This material is used in boatbuilding and other applications where durability is key, so it should stand up well to anything you throw at it!
