3D Printing Materials Acrylonitrile Butadiene Styrene (ABS)

ABS is a petroleum-based plastic.  ABS is non-biodegradable.  ABS is a strong and durable material.  Therefore it is used in various products including protective headgear, golf club heads, carrying cases, enclosures for electronic assemblies, kitchen appliances, and toys including Lego bricks.  ABS is soluble in acetone, i.e., nail polish remover.

ABS is extruded at temperatures of 210-250°C.  Heating up ABS causes fumes to be released.  These fumes are usually tolerable but may cause irritation in people with chemical sensitivities.  These fumes include chemicals that are known to be carcinogenic.  Therefore, 3D printing using ABS should be performed with caution and in places with adequate ventilation.

3D Printing Materials Poly Lactic Acid (PLA)

Poly Lactic Acid or PLA is made from organic material, for example, cornstarch, tapioca, or sugarcane.  PLA is used in the production of bags, food packaging, disposable utensils, plastic bags, and so on.  PLA is used as surgical implants such as anchors, rods, pins, or plates, since it.  If inserted in the body, PLA breaks into harmless lactic acid within 6 months to a couple of years.  The slow degradation helps the body to slowly take over the role of the implanted structure as it recovers.

Since PLA is made from renewable resources, it is one of the most environmentally friendly materials used for 3D printing.  PLA is extruded at a temperature of 160°C to 220°C.  Since PLA has a low melting temperature, parts made from PLA can warp under heated conditions.   When heated for 3D printing, PLA emits a sweet smell similar to corn.  These are not harmful fumes and therefore PLA can be used for 3D printing indoors.  PLA comes in most colors including translucent and glows in the dark. PLA cools slowly and therefore some 3D printers install a fan to cool down the 3D printed material.  When PLA cools down it is tough but rather brittle.  PLA has become a popular choice of material for 3D printing due to its environmental friendliness and low toxicity.

Organovo: 3d Printing Living Tissue

Organovo 3d Printing Living Tissue

According to the Organovo,” This is a medical research company headquartered in San Diego which designs and develops three-dimensional human tissue. The living 3D printed tissue can be used for testing drugs before giving the drugs to a real person.  Organovo uses a proprietary bioprinting platform called NovoGen for 3D printing tissue.

Pharmaceutical companies conventionally perform testing on animals or on cells in Petri-dishes.  Both methods of testing are very different from testing on a living person.  Therefore several clinical trials fail when tried on living person even if they were considered successful on animals or cells in petri-dish.  Organovo technology bridges this gap by providing 3D tissue models that are much closer to a living person.  Pharmaceutical companies can use the 3D tissues developed using this technology for testing.

In 2014 Organovo announced the commercial release of exVive3DTM Human Liver Tissue for preclinical drug discovery testing.  In April 2015, Organovo presented results of 3D printing in vitro 3D kidney tissue at the 2015 Experimental Biology conference in Boston.  In 2015 L’Oreal signed an agreement with Organovo to produce 3D printed skin for use in testing of cosmetics.  The long-term goal of Organovo’s 3D bioprinting technology is to be able to create organs for transplantation”.:)

Fab@Home: The DIY 3D Printer from Cornell

According to the Fab@home,” it was one of the first two open sources for do-it-yourself (DIY) 3D printer (the other open source DIY 3D printer was RepRap. The Fab@Home 3D printer utilizes syringe tools that can make objects out of multiple materials.  The first version of the Fab@Home print head had two syringes.  Later versions of Fab@Home 3D printers had more syringes going all the way up to eight syringes that could be used simultaneously.  Fab@Home 3D printers could be used with several materials including epoxy, silicone, food materials such as chocolate, cookie dough, and cheese, among others.

The Fab@Home project was started by Hod Lipson and Evan Malone of the Cornell University Computational Synthesis Laboratory in 2006.  Before the release of open source 3D printers the 3D printer market was dominated by industrial 3D printers.  The goal of Fab@Home was to make 3D printers more popular and accessible for common people.  The project was continued until 2012.  The project was considered complete when the rate at which do-it-yourself 3D printers and consumer printers were being distributed exceeded the rate of industrial 3D printers”.:)

CoLiDo Technology Making it Easy to Remove Printouts from 3D Printers

Image Posted on Updated on

According to the CoLiDo Technology,” it is easy to remove printouts from 3D printers. 3D printers print objects on a build tray.  The filament used for 3D printing objects (for example, PLA filament) is melted for creating the 3D printed objects and cools down on the build tray.  As the melted filament cools down, the generated object sticks firmly to the build tray.  Removing the object can be messy.  It often requires tools like cutters, knives, or hammers.  In the process, the object can break or the build tray can get scratched.

Colido 3D printers address the problem of the melted  filament sticking to the tray.  CoLiDo 3D printers use a patented glass platform that is coated by a material that prevents the melted filament from sticking to it.  This allows the 3D printed object to be removed easily.  CoLiDo printers show the temperature of the build tray so you know if it has cooled down.  Once the tray has cooled down sufficiently, one can remove the object with bare hands.  Any waste remaining on the tray can be wiped clean.

CoLiDo 3D printers and filaments are powered by Print-Rite.  Print-Rite is a leader in the aftermarket printer consumable industry.  Print-Rite is headquartered in Hong Kong and has manufacturing facilities in Zhuhai, Shanghai.  Print-Rite has over 1,800 patents in aftermarket printer consumables. Print-Rite provides information for the CoLiDo brand of 3D printers and related products through CoLiDo.com”.:)

ConforMIS: Customizing Knee Implants using 3D Printing

According to the ConforMIS,” this is a company headquartered in Bedford Massachusetts that designs and manufactures customized knee implants for patients  A CT scan of a patient’s knee is taken and a 3D model of the patient’ knee is created.  Using the 3D model, designs of implants customized to the patient are created.  3D printing technology is used to manufacture implants that are specific to that patient.  As a result, knee implants that are customized for a specific patient are generated.

Traditional knee replacement surgery is based on off the shelf implants.  A surgeon makes adjustments to the implants for a patient.  These adjustments may not result in a perfect fit for a patient and the implant can be either too big or too small.  In contrast, customized implants generated by ConforMIS’ technology are made to fit the knee of each patient.  Customized knee implants have been found to result in faster recovery, higher satisfaction, and improved ability to perform normal day to day activities.

Dr Philipp Lang, MD, MBA is the CEO and co-founder of ConforMIS.  ConforMIS owns or licenses approximately 470 patents and pending patent applications”.:)
