One of the problems that exist in the Prusa i3 3D printers is the open space and air circulation. This open space makes it difficult to warm the table, prevent it from reaching higher temperatures and makes it more difficult to maintain a constant temperature, which can compromise printing. If the temperature falls below a certain value, the part can be released from the table.
One of the things we wanted to acquire, for some time, was a 3D printer. But taking into account the prices and maintenance I decided to assemble my own. I decided to assemble it because the cost is lower and when it is necessary to perform maintenance, i know exactly what part purchase, where to buy and how to replace it.
