Tolerance Test for Joints

Tolerance Test for Joints on FDM printer

Assuming you have a cylinder with a diameter of 1mm and a circular hole of 1mm, in theory the interlocking can take place, but in practice the interlocking will not take place as there is always a need for a certain “tolerance”. Therefore, a cylinder with a diameter of 1mm can fit into a circular hole if it has a diameter of 1.1~1.4mm, that is, if there is a tolerance of 0.1~0.4 mm between the two objects. On the other hand, the tolerance cannot be applied at will but must be calculated accurately, as a tolerance that is too small will be insufficient to make the interlocking, while a tolerance that is too large will make the interlocking unstable, with the two objects passing through each other. … Read More

FDM printer nozzle size comparing

FDM 3D printers, including Longer 3D printers, are factory delivered with a 0.4 mm diameter nozzle. This diameter allows to obtain the best printing speed ratio and reproduction of the details, however it is always possible to install nozzle of different diameters according to different needs; examples are the 0.6, 0.8 and 1 mm nozzles. … Read More

Printing Temperature Calibration

How Printing Temperature Calibration on FDM printers

The printing temperature is a fundamental aspect if you want to achieve quality results. In fact, each type of filament requires a different printing temperature; for example, PLA requires temperatures between 190°C and 230°C, PETG requires temperatures between 220°C and 250°C, ABS requires temperatures between 230°C and 270°C, and so on. … Read More

FDM printer bridging printing tutorial

FDM printer bridging printing tutorial

The FDM 3D printing consists of a series of layers of molten material placed on top of each other; in this way, complex objects are created through a succession of layers. However, often some layers must be placed in areas without a base, so the layer is printed literally in a vacuum and it will inevitably fall down, but to overcome this problem it is possible to use supports, which act as a temporary scaffolding and can be removed once the print has been completed. … Read More
