What do ear molds look like?

Stahl’s ear

In a study, published in ‘Plos One,’ engineers and physicians at Weill Cornell Medical College describe how with 3-D printing and injectable gels they created living cells for ears that are virtually identical to a human ear. Over a three-month period, these flexible ears developed cartilage to replace the collagen used for molding.

To make the ears, Bonassar Lawrence, associate professor of biomedical engineering, and his colleagues started with a digitized 3-D image of a human subject’s ear and made it “solid” using a 3-D printer to assemble a mold. The ear developed with high-density gel has a gelatin-like consistency when the mold is removed, and the collagen serves as a scaffold on which the cartilage can grow.

Drawing of the ear and its parts

Without the existence of this helicoidal structure, which channels the sound like a funnel, the frontal waves would reach the ear tangentially and the hearing process would be less effective, since a large part of the sound would be lost:

The ear among the ancient polytheists was consecrated to Mnemosina for which reason they offered her some silver ears. One of the omens they attended to was the ringing of the ears. If the buzzing was felt in the right ear, it was a friend who spoke of them and if in the left, an enemy. This superstition has not been entirely banished among us.[2]

Drawing of an ear

Everything you need to know about the basic structure of ears to draw perfect characters. Illustrator Eridey explains in detail how to draw them from different angles and how to adapt them to fantastic characters like elves and fairies.

Generally speaking, all ears have the same pattern – it’s a magic formula!    Learning it by heart will be very easy after practicing a couple of times. Please use the model above to guide you through these steps:

In the following examples we will notice that some features are more pronounced or more subtle than others, but it’s simple to identify each part of these ears, so, if you draw from your imagination, the most important thing is to create coherent shapes:

If our character looks up or down, we can still use the same guides. But from a three-dimensional approach, remember that the head is a sphere and the location of the ears remains the same.

We’ve come this far and realized that drawing ears is not a big deal, but for those who are into animation or comic creation, saving time on details is of vital importance, try eliminating lines that you don’t think are necessary:

Stahl ear causes

A molding device for a human ear (1) comprising: a base section (105) defining an opening (103) sized to accommodate passage of the ear (1) through the opening (103), wherein the ear (1) includes an antehelix (14), an upper member (17) of the triangular phossa (16), a helix (10), a helical edge (11), a base, a shell (13) and a shell area (12), and the base section (105) includes a rear surface (108) and an anterior surface (107); andan upper section (102) which can be coupled so as to be released with the base section (105) defining a compartment between the two; characterized by: a first splint (31) disposed on the anterior surface (107) adapted to maintain a desired anatomical shape of the ear (1) in an area of the antehelix (14) and the upper member (17) of the fosatriangular (16).

The ear consists of a complex arrangement of cartilage covered by skin, which forms the characteristic shape of the ear (see Figure 1). Some of the fundamental structures of the ear are the helix, which is the outermost part of the ear and is characterized by a coil or rim (helical rim). The scaphoid (or scaphoid fossa) separates the helical rim from the antehelix which forms the defining curvature that separates the scaphoid from the concha. The antehelix gives rise to a Y-shaped structure that has two pillars. The two pillars form the fork of the Y and merge into the body of the antehelix. The area between the two pillars is the triangular pit. The deep recess leading to the ear canal is the concha bowl. It has an oblique and vertical component. The vertical component contributes to the projection of the ear and is continuous with the antehelix. Depending on the study, there may be an incidence of malformed or deformed ears in the newborn population of up to or greater than forty percent. A few among the various types of congenital ear deformities are protruding ears, cupped ears, ansiform ears, Stahl’s ear, concha pillar, malformed ears, helical rim compression, and Tanzer I-II contracted ear.
