How to print only infill pattern?

Hi there, lovely tech fans! It’s Carolina here, your go-to gal for all the delightful, nerdy tidbits about our wonderful world of technology. I have a juicy morsel for you today. Let’s dive right in and debunk the myths about 3D printing.


Ever Pondered on 3D Printing Without Infill?
Fret not, I’ve got you covered. Dive into this technological wonderland with me, and let’s discover the nuances of infill-free 3D printing together.

Printing 3D Without Any Infill?
Indeed! By simply adjusting the infill ratio to 0% or by harnessing the Spiralize Outer Contour feature in Cura, one can embark on an infill-less 3D printing journey. Nonetheless, for added sturdiness, don’t forget to tweak your wall thickness to something more than 1.2mm. But remember, not every design is suited for this technique.

For instance, a design that lacks a gentle gradient, making it reliant on support underneath, might struggle without infill. Some crafty individuals use removable supports, but remember, the base might be too feeble to stand alone.

Got a 3D prototype with a vast flat upper surface? You might need that infill or perhaps some extra support to achieve a perfect print.

Many tech enthusiasts design prototypes with minimal infill – less than 10% or sometimes none at all, especially for items like chic decorative artifacts, display items, or those that won’t face any stress.

A widespread myth is that a 3D print’s durability solely relies on its infill. Ah, not quite right! Elements like the exterior wall thickness and how your 3D model is oriented during printing are paramount for ensuring a robust 3D print.

Heard of the term bridging in the realm of 3D printing? It’s a nifty ability where a 3D printer can dexterously extrude material mid-air between two points sans any underlying support. If your printer masters this, and the model doesn’t demand an extensive bridge, voila, you can print without infill!

Oh, and the cherry on top? Skipping on infill can also be a huge timesaver! An acquaintance of mine reduced the infill to zilch, and his printing time was slashed by half!

Mastering the Art of 3D Printing Without Infill
To become a pro, enhance your model’s wall thickness, dial down the printing velocity, optimize cooling settings, and amplify top/bottom thickness parameters. Hunt for 3D designs tailored for infill-free printing. For some designs where total omission of infill is unfeasible, a minimal infill can work wonders.

Alternatively, try the Vase Mode in Cura, a trick that could further reduce your print duration. And here’s a fun tidbit: one tech lover dreamt of crafting a hollow action figure, laced with LED lights – talk about innovation!

When you opt for 0% infill, consider moderating the printing speed and perhaps tweaking the temperature settings. Whether it’s increasing or decreasing the temperature, experimenting will determine the ideal setting.

A tip from the techy trenches: Invest in a top-notch cooling fan for the best results in bridging. I came across a fascinating 3D print with just 1% infill – the results were spectacular.

Another genius idea floating around? Boosting the Wall Flow Rate to 115% sans infill, drilling base holes, and filling the inside with epoxy to solidify the model. Quick setting ClearWeld Epoxy, with a PSI strength of 4,400, can be a game-changer. Setting in mere minutes, it ensures your masterpiece is sturdy yet swiftly made.

Craving to 3D Print Infill Exclusively?
To achieve this, craft a block of your desired dimensions, pick your infill pattern, and set both Wall and Top/Bottom Thickness to zero. Once done, preview it to make sure it’s exactly what you had in mind.

There’s a plethora of infill designs to experiment with. But keep an eye on those patterns that don’t link with the walls. Settings like Connect Infill Lines should be unchecked by default, but it’s always wise to double-check.

If you’re having troubles getting your model to stick, try adding a Raft. I’ve witnessed a perfect Gyroid infill print using zero perimeters and no top or bottom layers with PrusaSlicer – the results were to die for!

The 3D printing world is vast and ever-evolving. With the right knowledge, tools, and a sprinkle of creativity, the sky’s the limit! So, until next time, keep exploring and stay tech-tastic!
