3D Printers Adhesive
You certainly know that adhesion is a key factor in achieving great results in 3D printing. Over the years I've had the opportunity to try different approaches, from mundane methods such as using for paper glue stick or medical glue, to the likes of hairspray and mousse, among others. At the same time, the surfaces I have had to work with have also undergone significant changes and today my choices lean towards solutions such as PEA and analogs.
Clearly, there is no one-size-fits-all adhesive for different types of plastic. One adhesive may hold the parts perfectly when printing, while another may be useless. This is where our well-known adhesive comes into play, and it performs best when combined with materials such as ABS and others.
However, what makes this glue truly unique is the way it is applied. We take an ordinary glue stick and dissolve it in hot water at about 80 degrees Celsius. And for application we use something unusual - a chalk marker, which can be easily purchased empty and choose the width of your choice, for example, 3 cm, although wider options are available, up to 5 cm. With this tool, we get a perfectly even coating that can easily cope with any task.
Update:
PVP K90 (Polyvinylpyrrolidone K90) can be used as an adhesion agent when working with 3D printers, especially with technologies using plastic materials such as ABS and PLA. An adhesion agent helps prevent detachment or deformation of the printed object during the printing process, ensuring a more reliable attachment to the printer's build platform.
Here's how you can use PVP K90 as an adhesion agent:
- Prepare the PVP K90 solution: Dissolve PVP K90 in water to achieve the desired consistency. Typically, concentrations from 3% to 10% are used. The specific ratio depends on the platform material and adhesion requirements.
- Apply the solution to the build platform: Apply the PVP K90 solution to the surface of the 3D printer's build platform. You can use a brush, cotton swab, or applicator to evenly distribute the solution.
- Let the solution dry: After applying the PVP K90 solution, allow it to dry to create a thin adhesion layer.
- Start printing: Print your object as usual. The plastic material should securely adhere to the PVP K90 adhesion layer.
- After printing, carefully remove the object: After completing the print, let the object cool down, and then gently remove it from the build platform.
It's important to remember that the effectiveness of PVP K90 as an adhesion agent may depend on various factors such as the type of printing material, printer settings, and environmental conditions. Therefore, it's recommended to conduct small tests to determine the optimal parameters for your specific situation. Also, make sure to provide proper ventilation when using PVP K90 to avoid inhaling fumes.
Certainly, I can add that PVP (Polyvinylpyrrolidone) is also commonly used in the manufacture of glue-stick. PVP is a versatile polymer that can be found in various adhesive products, including stationery or office glues. Its adhesive properties make it an excellent choice for creating adhesives that are used for paper-based projects, crafts, and everyday office tasks.
For using the solution in a marker, I used a stronger concentration. However, if you plan to use the solution with a spray, I would recommend diluting it by adding more water, for example, up to 5 times more. This is not a strict rule, and you can adjust the solution concentration as you see fit.
