Three-dimensional printed modelling of diffuse low-grade gliomas and associated white matter tract anatomy. Medical applications for 3D printing are expanding rapidly and are expected to revolutionize health care.1 Medical uses for 3D printing, both actual and potential, can be organized into several broad categories, including: tissue and organ fabrication; creation of customized prosthetics, implants, and anatomical models; and pharmaceutical research regarding drug dosage forms, delivery, and discovery.2 The application of 3D printing in medicine can provide many benefits, including: the customization and personalization of medical products, drugs, and equipment; cost-effectiveness; increased productivity; the democratization of design and manufacturing; and enhanced collaboration.1,36 However, it should be cautioned that despite recent significant and exciting medical advances involving 3D printing, notable scientific and regulatory challenges remain and the most transformative applications for this technology will need time to evolve.35,7, Three-dimensional (3D) printing is a manufacturing method in which objects are made by fusing or depositing materialssuch as plastic, metal, ceramics, powders, liquids, or even living cellsin layers to produce a 3D object.1,8,9 This process is also referred to as additive manufacturing (AM), rapid prototyping (RP), or solid free-form technology (SFF).6 Some 3D printers are similar to traditional inkjet printers; however, the end product differs in that a 3D object is produced.1 3D printing is expected to revolutionize medicine and other fields, not unlike the way the printing press transformed publishing.1, There are about two dozen 3D printing processes, which use varying printer technologies, speeds, and resolutions, and hundreds of materials.9 These technologies can build a 3D object in almost any shape imaginable as defined in a computer-aided design (CAD) file (Figure 1).9 In a basic setup, the 3D printer first follows the instructions in the CAD file to build the foundation for the object, moving the printhead along the xy plane.5 The printer then continues to follow the instructions, moving the printhead along the z-axis to build the object vertically layer by layer.5 It is important to note that two-dimensional (2D) radiographic images, such as x-rays, magnetic resonance imaging (MRI), or computerized tomography (CT) scans, can be converted to digital 3D print files, allowing the creation of complex, customized anatomical and medical structures (Figure 2).3,5,10, A 3D printer uses instructions in a digital file to create a physical object.12, Radiographic images can be converted to 3D print files to create complex, customized anatomical and medical structures.12, Charles Hull invented 3D printing, which he called stereolithography, in the early 1980s.1 Hull, who has a bachelors degree in engineering physics, was working on making plastic objects from photopolymers at the company Ultra Violet Products in California.6 Stereolithography uses an .stl file format to interpret the data in a CAD file, allowing these instructions to be communicated electronically to the 3D printer.6 Along with shape, the instructions in the .stl file may also include information such as the color, texture, and thickness of the object to be printed.6, Hull later founded the company 3D Systems, which developed the first 3D printer, called a stereolithography apparatus. 6 In 1988, 3D Systems introduced the first commercially available 3D printer, the SLA-250.6 Many other companies have since developed 3D printers for commercial applications, such as DTM Corporation, Z Corporation, Solidscape, and Objet Geometries.6 Hulls work, as well as advances made by other researchers, has revolutionized manufacturing, and is poised to do the same in many other fieldsincluding medicine.6, 3D printing has been used by the manufacturing industry for decades, primarily to produce product prototypes.1,9 Many manufacturers use large, fast 3D printers called rapid prototyping machines to create models and molds.11 A large number of .stl files are available for commercial purposes.1 Many of these printed objects are comparable to traditionally manufactured items.1, Companies that use 3D printing for commercial medical applications have also emerged.2 These include: Helisys, Ultimateker, and Organovo, a company that uses 3D printing to fabricate living human tissue.2 At present, however, the impact of 3D printing in medicine remains small.1 3D printing is currently a $700 million industry, with only $11 million (1.6%) invested in medical applications.1 In the next 10 years, however, 3D printing is expected to grow into an $8.9 billion industry, with $1.9 billion (21%) projected to be spent on medical applications.1, 3D printing technology is rapidly becoming easy and inexpensive enough to be used by consumers.9,11 The accessibility of downloadable software from online repositories of 3D printing designs has proliferated, largely due to expanding applications and decreased cost.2,4,11 It is now possible to print anything, from guns, clothing, and car parts to designer jewelry.2 Thousands of premade designs for 3D items are available for download, many of them for free.11, Since 2006, two open-source 3D printers have become available to the public, Fab@Home (www.fabathome.org) and RepRap (www.reprap.org/wiki/RepRap).6,9 The availability of these open-source printers greatly lowered the barrier of entry for people who want to explore and develop new ideas for 3D printing.9 These open-source systems allow anyone with a budget of about $1,000 to build a 3D printer and start experimenting with new processes and materials.9, This low-cost hardware and growing interest from hobbyists has spurred rapid growth in the consumer 3D printer market.11 A relatively sophisticated 3D printer costs about $2,500 to $3,000, and simpler models can be purchased for as little as $300 to $400.8,11 For consumers who have difficulty printing 3D models themselves, several popular 3D printing services have emerged, such as Shapeways, (www.shapeways.com), Thingiverse (www.thingiverse.com), MyMiniFactory (www.myminifactory.com), and Threeding (www.threeding.com).11.

New world of 3-D printing offers completely new ways of thinking: Q & A with author, engineer, and 3-D printing expert Hod Lipson. 3D Printing in Medicine publishes 3D printing innovation that impact medicine. Loke et al. An SLS printer uses powdered material as the substrate for printing new objects.11 A laser draws the shape of the object in the powder, fusing it together.11 Then a new layer of powder is laid down and the process repeats, building each layer, one by one, to form the object.11 Laser sintering can be used to create metal, plastic, and ceramic objects.11 The degree of detail is limited only by the precision of the laser and the fineness of the powder, so it is possible to create especially detailed and delicate structures with this type of printer.11, Inkjet printing is a noncontact technique that uses thermal, electromagnetic, or piezoelectric technology to deposit tiny droplets of ink (actual ink or other materials) onto a substrate according to digital instructions.10 In inkjet printing, droplet deposition is usually done by using heat or mechanical compression to eject the ink drops.10 In TIJ printers, heating the printhead creates small air bubbles that collapse, creating pressure pulses that eject ink drops from nozzles in volumes as small as 10 to 150 picoliters.10 Droplet size can be varied by adjusting the applied temperature gradient, pulse frequency, and ink viscosity.10, TIJ printers are particularly promising for use in tissue engineering and regenerative medicine.10,13 Because of their digital precision, control, versatility, and benign effect on mammalian cells, this technology is already being applied to print simple 2D and 3D tissues and organs (also known as bioprinting).10 TIJ printers may also prove ideal for other sophisticated uses, such as drug delivery and gene transfection during tissue construction.10, FDM printers are much more common and inexpensive than the SLS type.11 An FDM printer uses a printhead similar to an inkjet printer.11 However, instead of ink, beads of heated plastic are released from the printhead as it moves, building the object in thin layers.4,11 This process is repeated over and over, allowing precise control of the amount and location of each deposit to shape each layer.4 Since the material is heated as it is extruded, it fuses or bonds to the layers below.4 As each layer of plastic cools, it hardens, gradually creating the solid object as the layers build.11 Depending on the complexity and cost of an FDM printer, it may have enhanced features such as multiple printheads.11 FDM printers can use a variety of plastics.11 In fact, 3D FDM printed parts are often made from the same thermoplastics that are used in traditional injection molding or machining, so they have similar stability, durability, and mechanical properties.4, The greatest advantage that 3D printers provide in medical applications is the freedom to produce custom-made medical products and equipment.3 For example, the use of 3D printing to customize prosthetics and implants can provide great value for both patients and physicians.3 In addition, 3D printing can produce made-to-order jigs and fixtures for use in operating rooms.4 Custom-made implants, fixtures, and surgical tools can have a positive impact in terms of the time required for surgery, patient recovery time, and the success of the surgery or implant.4 It is also anticipated that 3D printing technologies will eventually allow drug dosage forms, release profiles, and dispensing to be customized for each patient.5, Another important benefit offered by 3D printing is the ability to produce items cheaply.1 Traditional manufacturing methods remain less expensive for large-scale production; however, the cost of 3D printing is becoming more and more competitive for small production runs.1 This is especially true for small-sized standard implants or prosthetics, such as those used for spinal, dental, or craniofacial disorders.3 The cost to custom-print a 3D object is minimal, with the first item being as inexpensive as the last.1 This is especially advantageous for companies that have low production volumes or that produce parts or products that are highly complex or require frequent modifications.4, 3D printing can also reduce manufacturing costs by decreasing the use of unnecessary resources.5 For example, a pharmaceutical tablet weighing 10 mg could potentially be custom-fabricated on demand as a 1-mg tablet.5 Some drugs may also be printed in dosage forms that are easier and more cost-effective to deliver to patients.5, Fast in 3D printing means that a product can be made within several hours.4 That makes 3D printing technology much faster than traditional methods of making items such as prosthetics and implants, which require milling, forging, and a long delivery time.3 In addition to speed, other qualities, such as the resolution, accuracy, reliability, and repeatability of 3D printing technologies, are also improving.3, Another beneficial feature offered by 3D printing is the democratization of the design and manufacturing of goods.4 An increasing array of materials is becoming available for use in 3D printing, and they are decreasing in cost.4 This allows more people, including those in medical fields, to use little more than a 3D printer and their imaginations to design and produce novel products for personal or commercial use.4, The nature of 3D printing data files also offers an unprecedented opportunity for sharing among researchers.6 Rather than trying to reproduce parameters that are described in scientific journals, researchers can access downloadable .stl files that are available in open-source databases.6 By doing so, they can use a 3D printer to create an exact replica of a medical model or device, allowing the precise sharing of designs.6 Toward this end, the National Institutes of Health established the 3D Print Exchange (3dprint.nih.gov) in 2014 to promote open-source sharing of 3D print files for medical and anatomical models, custom labware, and replicas of proteins, viruses, and bacteria (Figure 3).12, The NIH 3D print exchange is a free online resource for sharing medical and scientific 3D print files and tutorials.12. (29) who divided 60 pediatric residents into two groups, 29 participating in the control group and 31 in the intervention group. According to the appropriateness guidelines developed by the SIG, 3D-printed models have shown advantages and usefulness in patients with complex skull, facial and mandibular fractures, and temporomandibular joint disorders, benign and malignant tumors (16). The organization estimates it has delivered about 1,800 hands so far, mostly to children, but it believes that another 1,800 have been produced outside of its documented process. Hopefully, it reduces morbidity and mortality, he said. 3D printing has shown increasing applications in the medical field over the last decades with reports covering different areas which range from its original applications in orthopedics to cardiovascular disease and tumor imaging (11-15).

This represents a novel approach for improving fenestration accuracy on the stent graft, although further research on more cases is needed. 3D printing, also known as additive manufacturing (AM), is a rapidly developing manufacturing technology, has gradually become an emerging and crucial adjunctive tool in medicine, and is the preferred method for fabrication of organ models. Aprecia Pharmaceuticals' Spritam (levetiracetam), an anti-epileptic drug, is the first and only 3D-printed pharmaceutical. Despite these promising results, clinical trials with inclusion of a large cohort of data at multiple clinical sites are needed. Medical 3D printing was once an ambitious pipe dream. Over a duration of 3-year period, 928 cardiothoracic surgeries were performed at their pediatric hospital, of which 164 anatomical models were generated for different purposes, such as education, patient-doctor communication, pre-surgical intervention and planning. Then we potentially have a better surgical outcome, Ryan said.

Tissue or organ failure due to aging, diseases, accidents, and birth defects is a critical medical problem.10 Current treatment for organ failure relies mostly on organ transplants from living or deceased donors.10 However, there is a chronic shortage of human organs available for transplant.1,10 In 2009, 154,324 patients in the U.S. were waiting for an organ.10 Only 27,996 of them (18%) received an organ transplant, and 8,863 (25 per day) died while on the waiting list.10 As of early 2014, approximately 120,000 people in the U.S. were awaiting an organ transplant.1 Organ transplant surgery and follow-up is also expensive, costing more than $300 billion in 2012.10 An additional problem is that organ transplantation involves the often difficult task of finding a donor who is a tissue match.1 This problem could likely be eliminated by using cells taken from the organ transplant patients own body to build a replacement organ.1,13 This would minimize the risk of tissue rejection, as well as the need to take lifelong immunosuppressants.1,13, Therapies based on tissue engineering and regenerative medicine are being pursued as a potential solution for the organ donor shortage.1,10 The traditional tissue engineering strategy is to isolate stem cells from small tissue samples, mix them with growth factors, multiply them in the laboratory, and seed the cells onto scaffolds that direct cell proliferation and differentiation into functioning tissues.7,10,13 Although still in its infancy, 3D bioprinting offers additional important advantages beyond this traditional regenerative method (which essentially provides scaffold support alone), such as: highly precise cell placement and high digital control of speed, resolution, cell concentration, drop volume, and diameter of printed cells.10,13 Organ printing takes advantage of 3D printing technology to produce cells, biomaterials, and cell-laden biomaterials individually or in tandem, layer by layer, directly creating 3D tissue-like structures.13 Various materials are available to build the scaffolds, depending on the desired strength, porosity, and type of tissue, with hydrogels usually considered to be most suitable for producing soft tissues.6,7, Although 3D bioprinting systems can be laser-based, inkjet-based, or extrusion-based, inkjet-based bioprinting is most common.13 This method deposits bioink, droplets of living cells or biomaterials, onto a substrate according to digital instructions to reproduce human tissues or organs.13 Multiple printheads can be used to deposit different cell types (organ-specific, blood vessel, muscle cells), a necessary feature for fabricating whole heterocellular tissues and organs.13 A process for bioprinting organs has emerged: 1) create a blueprint of an organ with its vascular architecture; 2) generate a bioprinting process plan; 3) isolate stem cells; 4) differentiate the stem cells into organ-specific cells; 5) prepare bioink reservoirs with organ-specific cells, blood vessel cells, and support medium and load them into the printer; 6) bioprint; and 7) place the bioprinted organ in a bioreactor prior to transplantation.13 Laser printers have also been employed in the cell printing process, in which laser energy is used to excite the cells in a particular pattern, providing spatial control of the cellular environment.13, Although tissue and organ bioprinting is still in its infancy, many studies have provided proof of concept.
