At the moment, it isn't possible for us to estimate what you will be charged in customs duties when you import a printer into your country. 3D printers are a fairly new technology and not all countries have decided how they're going to classify 3D printers when duties are calculated. Those countries that have, haven't necessarily decided to classify 3D printers the same way.
There are some tools that you can use to try to find out though. Most countries have adopted the Harmonized Tariff Schedule to classify imports. A web search for "[your country] tariff schedule 3D printer" may bring up some helpful articles.
You can also contact a customs broker in your country to get more information about imports.
