3D Printing Tech Tips: Preventing Nozzle Jams Using Canola Oil

When it comes to 3D printing large objects (such as this 27” tall Frankenstein head, or this full-size 3D figure), there are several factors to keep in mind. For example, a leveled print bed is the foundation of a successful print, therefore, make sure to verify the bed level before starting a print (Read Guide to Level the Print Bed). If a 3D print requires using two materials or colors, make sure the nozzles are calibrated and aligned correctly (Guide to Change and Calibrate a Nozzle). For both small and large scale 3D prints, prepare the print bed with beer or other solution to promote good bed adhesion (Read Guide to Prepare Print Bed). Among these success factors, ensuring a well lubricated and jam-free nozzle is one of the most important. In this blog, we are going to walk through a simple canola oil treatment that will help prevent nozzles from jamming and clogging, especially when printing big 3D prints.

3D Printing Tips: The Simple Canola Oil Treatment

The canola oil treatment, also known as the process of “seasoning the nozzle,” helps lubricate the nozzle, prevents material build-up inside the nozzle, and improves overall print reliability. This process can be done before starting a new print, or while the print is running. We recommend performing this procedure every other day, or before starting a big print.
Step 1: – Dab a drop of canola oil on a piece of paper towel. Step 2: – Rub the paper towel with the oil on the filament that is feeding into the extruder. Step 3: – Extrude approximately 100 – 200 mm of filament to ensure the oil is evenly distributed.

Video Tutorial: Why Canola Oil? The canola oil treatment technique has been used among FFF 3D printer users for many years. It is believed to be one of most simple and effective ways to prevent nozzles from jamming and clogging. Because PLA material has a lower melting point (at right around 200°C), this technique works especially well with using PLA, as well as when switching between different material types. Final Notes Canola oil’s smoke point is approximately 204°C, and fire point is around 400°C (Reference: this technique will lubricate the nozzle without causing a fire hazard.
