How do you use support blockers in Cura?

Dive Deep into the Wonders of Cura Support Blockers!


Enthusiastic tech-nerd Carolina here, utterly captivated by all things tech, and today I’m thrilled to guide you on an exhilarating journey through the maze of Cura’s support blockers. Unlock the potential to optimize your 3D printing, saving on both time and filament!

Hesitant about superfluous supports on your print? That’s where the magical Cura support blocker jumps into action!

To make this fun, I’m going to use the ever-quirky among us model as our guide. Ready?

Load Your Model:
Start by importing your model into Cura. Peek at the top-right corner to explore print settings. You’ll want to tap on the generate support option, setting your model up for success!

Ah, and don’t forget about the support overhang angle. While there isn’t a one-size-fits-all number, a decent starting point? 45 degrees.

Slice and Preview Model:
After you’ve chosen to support, it’s time to slice! See the time and filament estimation for your upcoming 3D masterpiece. Post-slicing, a glimpse at the preview unveils a delightful color play. Your model might transition from a gleaming yellow to a fiery red, while the support adopts a serene blue shade. Neat, right?

Select Support Blocker:
Post preview, you’ll get clarity on which zones require support and which can do without. Jump back to the Prepare phase and scout for the support blocker symbol. Position it over redundant support zones. Our among us model, for instance, benefits from blockers on its base and beneath its head accessory.

Modify the Size of the Support Blocker:
Under our blocker icon lies the object list – our directory for models and blockers. Modifying blocker size is a breeze! Highlight, choose, and adjust using the X, Y, and Z values. Don’t want uniform changes? Turn off that uniform scaling option.

Adjust the Position of the Support Blocker:
Positioning perfection is key! For precision, adjust your view, zooming in and out. Ensure your blocker aligns well with areas you intend to be support-free.

Preview and Slice Model Again:
Post adjustments, re-slice. Aim for a preview devoid of any blue hues where blockers were placed.

Tip Time: For intricate areas, like spaces or holes, individual blockers or a single resized blocker can do wonders. It’s all about choosing the technique that suits your model!
