Vapor smoothing (or chemical vapour smoothing) is a post-processing technique that smooths the surface of a 3D printed part by exposing its material to a vapourised solvent in a controlled environment. The process technology is able to enhance surface finish, from smoothness to cosmetic appearance, while furthering a part’s tensile strength without affecting its mechanical performance. Vapour smoothing is the solution for quick, high quality and repeatable results in post-processing 3D printed parts.
3D Printing has revolutionized the manufacturing industry, allowing for the creation of complex and intricate designs with ease. While 3D printing holds many benefits, the final product can sometimes have a rough and porous surface finish. Vapour smoothing can overcome this issue when applied to MJF PA12 3D printed items.
The chemical vapor can soften and partially dissolve the surface material of a 3D printed part. In the case of MJF PA12 3D printed parts on AMT PostPro, vapor smoothing not only improves the surface finish but also increases the strength of the final product.
This chemical vapor smoothing process for PA12 parts on AMT PostPro typically involves the following steps:
1. 3D printed parts are loaded into the PostPro machine on hooks and prepared for operation
2. The PostPro machine is filled with the appropriate solvent for the PA12 material
3. The PostPro recipe is run to allow the solvent vapor to smooth the surface of the parts. The amount of time required varies on the size and complexity of the parts, as well as the desired level of smoothing
4. The smoothed parts are removed from the PostPro machine and allowed to dry and cure before further use or finishing
The Benefits to Vapour Smoothing
One of the primary advantages of vapor smoothing is the increase in strength of the 3D printed part. The solvent used in the process partially dissolves the outer layers of the part, filling in the porous areas and creating a solid, dense surface. This results in a stronger and more durable product, making it ideal for applications that require high strength and toughness.
Another advantage to vapor smoothing is surface sealing. The solvent used in the process seals the surface of the part, making it more resistant to wear and tear, as well as protecting it from environmental factors such as moisture and temperature changes. This is particularly beneficial for applications where the 3D printed part will be exposed to harsh conditions, ensuring that the final product has a longer lifespan.
The post-processing technique is highly utilised throughout the medical and automotive industries for its controlled process, lack of chemical residue, and non-hazardous finish to 3D printed parts. Additionally, AMT PostPro meets US and EU safety standards with UL & CE marks for use of vapour smoothing in construction applications.
Vapor Smoothing is a highly effective post-processing technique for MJF PA12 3D printed items. It improves the surface finish, increases the strength of the final product, and seals the surface, making it more resistant to wear and tear. By choosing IPFL chemical vapor smoothing for your MJF PA12 3D printed parts, you can ensure that your final product will not only be aesthetically pleasing but also durable and functional.
