Markiplier's "Iron Lung" Film and 3D-Printed Popcorn Buckets

Mark Fischbach, known as Markiplier, has directed, acted in, edited, and financed "Iron Lung," a film based on David Szymanski’s horror game. The movie is set after a cosmic event and follows a prisoner navigating a submarine through an ocean of blood on a barren moon. The film emphasizes claustrophobia and psychological horror.

To promote the film, Regal Cinemas is allowing fans to bring 3D-printed popcorn buckets to theaters for free popcorn. However, there are warnings regarding the safety of using 3D-printed materials for food consumption. Polylactic acid (PLA), a common 3D printing material, can harbor bacteria due to its porous nature and may not be safe for repeated use with food. Proper sealing and alternative materials like polyethylene terephthalate glycol (PETG) are recommended for safer use.

The 3D-printed bucket design involves two parts, potentially leading to material waste and assembly challenges. Supports required during printing can also add to the cost and complexity of the project.

The film is a claustrophobic sci-fi horror and may not be for everyone.

Common 3D printing materials like PLA can harbor bacteria and may not be food safe without proper sealing or using alternative materials like PETG.

The design is available on Thingiverse.

No, printing the "Iron Lung" bucket can be costly due to material usage and the need for supports.
