Digital technologies/3D printing/3D printing- Intermediate/Selecting Nozzle Sizes

Nozzle size is the first decision to make when 3D printing. Within Makerspace, there are four options of nozzle size using the Ultimaker 2+, 0.25mm, 0.4mm, 0.6mm, and 0.8mm. Choosing between the options depends on the fine details of the model and the print speed required.

• A smaller nozzle size will allow for finer details and better dimension accuracy. However, it will also take longer to print the model.
• A larger nozzle can provide faster print time and also create stronger prints.
• A smaller nozzle diameter can cause it to be more difficult to print with overhangs as each layer has less width to adhere to the next one.
• However, with a smaller nozzle, the supports are easier to remove as the printer will use less material for supports making it easier to break away.
• A larger nozzle is able to print with less infill as the walls would be thicker to ensure strength.
