How Does a 3D Printer Works?

 Resin printers use a photo-curing liquid resin which, stimulated by beams of light (via LCD , DLP or SLA ), solidifies into the desired shape. The printing base is immersed inside the liquid, which is stimulated only in the points to be solidified. Again the height of the model is done in layers, but the result has a smooth and glossy finish, and not streaked like with filament printing. You can easily check and buy a wide range of 3D printers at 3D Printers Point.

Printing Accuracy
How to understand the accuracy of a 3D printer starting from the manufacturer's specification list? Very simple, most manufacturers report the accuracy of a specific model with two values: positioning accuracy, which indicates the accuracy in the movements performed by the extruder nozzle, and printing accuracy which, on the other hand, indicates the differences in thickness between the digital model. and 3D printed object at the end of the procedure. In both cases, the accuracy of a 3D printer is measured in millimeters ( mm ), and is to be expected for both values from 0.1mm to 0.3mm for the cheaper models. The more expensive models, on the other hand, can also boast values of about 0.01mm, with differences perceptible even to the naked eye.

Print speed
The speed of a 3D printer is a factor to consider only relatively in the choice, whatever the final use of the product. In any case, the 3D printing process will be a slow process, and many printers allow you to choose different settings to reduce the printing speed in order to obtain a higher quality final result. In any case, manufacturers report the speed in mm / s ( millimeters per second ), representing the printer's ability to place that amount of filament on the platform in one second. This is a value that can vary based on different characteristics, for example, based on the material used and the desired print quality, so manufacturers often declare a print speed on multiple values, such as 20 ~ 100mm, which therefore it can vary from 20 to 100mm according to the configurations.

Print Size
On the other hand, the print dimensions are very important, i.e. the ability of the 3d printer to create more or less large objects. Domestic models are rather limited in this aspect due to the overall size of the structure: usually, non-professional products can guarantee prints of objects that are wide, high and deep about 20cm (centimeters), going up to around 40cm. Of course, as the print surface (and volume) increases, the size and weight of the printer itself will also increase.

Other Characteristics:
After analyzing the essential features of a 3D printer, let's move on to the other features to keep in mind when buying. Just like traditional printers, 3D printers can also be connected to a computer via USB cable or via Wi-Fi. In this case, it is useful to pay attention to compatibility with the operating system , although almost all models can be used with Windows PCs, Macs, and Linux computers.
