To determine the size of your 3D printer, you need to focus on its build volume, which refers to the maximum dimensions of an object that the printer can create. You can figure out the build volume by using a measuring tool on each part of your 3D printed object. Here's how you can accurately ascertain this:
Measuring Your 3D Printer's Build Volume
There are two main methods you can use:
-
Direct Measurement:
-
Measure the build plate: Use a ruler or measuring tape to determine the length, width, and height of the build platform. This is the area where your print will reside.
-
Determine the maximum Z-height: Measure the maximum distance the print head can move along the Z-axis (vertically).
-
Combine the measurements: Use these measurements to get the effective build volume, typically expressed in millimeters (mm) or inches. For example, if the build plate is 200 mm x 200 mm and the maximum Z-height is 200 mm, the build volume is 200mm x 200mm x 200mm.

Using a Calibration Cube:
-
Design a cube: Create a simple 3D model of a cube with known dimensions. For example, a 50mm x 50mm x 50mm cube.
-
Print the cube: Print this cube using your printer.
-
Measure the print: Use a measuring tool to check the dimensions of the printed cube. This step confirms that the printer is working as expected and gives an idea of the overall size of the printing area. If it doesn't match exactly with the design, this shows that the printer is not perfectly calibrated.
-
Visual estimation: Place the printed cube inside your design before printing. This helps to know if your object will fit the printer and allows you to see the space the object will occupy on the printer's build plate and therefore how big your printing space is.
-
Determine occupied volume: Consider the space the cube and your object occupy together inside the tray as an approximation of the maximum possible printing volume.

Tips For Accurate Measurement
- Check specifications: Refer to your printer's manual or the manufacturer's website. This information often includes the exact dimensions of your printer's build volume.
- Account for tolerances: Always leave a bit of tolerance space when designing a print. A print that exactly matches your 3D printer maximum dimensions may cause problems.
- Repeat measurements: To minimize error, repeat your measurements multiple times, especially if you are manually measuring each dimension.
- Use digital calipers: Consider using digital calipers for more precise measurements of both your printer’s printing area and your print.
By employing these methods, you can accurately determine the size of your 3D printer's build volume and ensure that your designs fit within these limits.
