“…However, clinically, the ear aiming to reconstruct should be mirror-symmetrical to the contralateral normal ear. CAD/CAM, as a novel technique, has been widely used for the fabrication of anatomically accurate 3D models (Bill et al, 1995;Ciocca et al, 2007;Erickson et al, 1999;Subburaj et al, 2007). Particularly, this method can accurately perform complicated manipulations of the original 3D data, including Boolean operations, mirror imaging, and scaling Ciocca, Scotti, 2004;KarayazganSaracoglu et al, 2009).…”

“…Medical imaging data can now feasibly be used to construct patient representative models and could potentially supersede impression/cast based approaches when attempting to reconstruct a defective or uncompromised area of anatomy. The use of medical imaging data offers several advantages both in terms of resolution of topography reproduction, in addition to being minimally invasive to the patient, part of routine clinical practise, while also capturing useful information of the wider patient anatomy for model construction and virtual placement analysis [7,8]. Modern digital CAD software offers multiple advantages to the traditional design process as no model fabricating is required and designs are digitally evaluated and stored, reducing costs and readily allowing for future reproduction.…”

We investigate the use of medical imaging, digital design and 3D printing technologies as a viable means of reproducing a person’s anatomy, with the intension of producing a working, patient specific prosthesis. This approach offers several advantages over traditional techniques, as data capture is non-intrusive, models can be made using quantitative methodologies, design iterations can be digitally stored for future reproduction, and additive manufacturing ensures no loss of quality when converting the digital model into a physical part. We also present a combined model segmentation with multi-material printing approach to increase the colour complexity of the final model. When combined with multi-material printing using elastic materials, our approach provides a comprehensive strategy to accurately realising mimic of both skin pigmentation and the tactile feel of human tissues. Ultimately, we believe our approach provides an innovative strategy for prosthesis production which could have considerable potential for implementation in a clinical setting.

“…Cheah et al employed rapid prototyping techniques to fabricate a master pattern "mould" to cast the final prosthesis by integrating laser surface digitizing/scanning and CAD/CAM to achieve automated fabrication of anatomically accurate extra-oral facial prostheses [4,5]. Several techniques have also been reported describing the fabrication of mirror-image wax casts for maxillofacial prostheses [10][11][12][13][14], however it was acknowledged that these techniques are costly and may require more time than manual fabrication. Recently, Eggbeer et al employed additive manufacturing techniques to undertake the direct manufacture of a body prosthesis from an optical method of data capture, digital design and a 3D printing process which could then be wrapped in a thin layer of colour-matched silicone elastomer [15], and thus bring the process of utilising rapid prototyping technology in this field one step closer.…”

Objectives: 3D colour printing, a method of additive manufacturing, has been developed and utilised to produce facial soft tissue prostheses. This was achieved by layered fabrication of a biocompatible powder held together by an aqueous binder containing a resin and coloured inks, followed by infiltration with a medical grade silicone polymer. The aim of this study was to investigate the elastomer infiltration depths within the 3D printed models.Methods: Three sets of 30 cubes -20x20x20 mm -were used to investigate the infiltration depth of Sil-25 maxillofacial silicone polymer (an MSP) under atmospheric pressure, 2 bar and 3 bar pressure for 5, 10, 15, 20 and 25 min. The investigation was also repeated with two other MSPs -Promax-10 and M-3428 -under 3 bar pressure. Following infiltration, the cubes were bisected, the internal aspects stained with dye, and the infiltration depth measured using a travelling microscope. Infiltration quality was also assessed using scanning electron microscopy (SEM). Results:At standard atmospheric pressure, the maximum infiltration depth of Sil-25 was 1.45 mm after 25 min. However, after 25 min at 2 and 3 bars pressure, the infiltration depth increased to 3.9 mm and 8.7 mm, respectively. At 3 bars the infiltration depth of Promax-10 and M-3428 was 2.4 mm and 7.5 mm, respectively. In all samples SEM revealed a disorganised distribution of starch particles within the MSP infiltrate.Significance: Pressure significantly increased the infiltration rate and depth of the MSPs within 3D printed constructs. The infiltration depth obtained is sufficient for prostheses that are less than 16 mm thick.
