# Polysher™
> The Polysher has been discontinued and is no longer available for purchase
The Polysher™ is a desktop post processing unit designed to remove layer lines from PolySmooth™ and PolyCast™ prints. The Polysher™ uses Polymaker’s Layer-Free™ technology to create a fine mist of alcohol which evenly smooths the model.

## FAQ
Can the Polysher™ be used with other solvent than IPA?
No, the nebulizer is designed and calibrated to only work with IPA, moreover other solvents may damage the Polysher™.\
The Polysher™ will not work with PLA.
How often do I need to change the nebulizer?
The nebulizer membrane may develop micro-cracks over time which may affect the mist production performance. We recommend changing the nebulizer when you notice a drop in your mist density or height. The nebulize can usually last \~100hours of polishing time. The Polysher™ comes with 2 nebulizers.\
Additional nebulizers can be found [here.](https://us.polymaker.com/products/nebulizer-pack)
Does the Polysher™ uses a heat source to work?
No, for additional safety we have developed a technology using a nebulizer to create a mist of micro droplet which will evenly smooth your 3D printed part.\
NOTE: We do not heat up the IPA and use the vapor to smooth the 3D print.
What do I do if I have an issue with my Polysher?
Please first review [THIS DOCUMENT](https://cdn.shopify.com/s/files/1/0548/7299/7945/files/Customer_Service_Polysher_0cd107a1-c3d8-460c-8c22-b7bc5c3ed01b.pdf?v=1734712428). If that does not help - please contact us by visiting the contact us page, or by starting a chat in the bottom right corner of the screen.
Where can I find extra trays?
We do not sell these separately but you can print [THIS ](https://www.thingiverse.com/thing:2340676)file and it should work great. Just do not print it in a PVB material. PLA or ABS should work fine.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://wiki.polymaker.com/polymaker-products/accessories/polysher-tm.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
