3D Printing Lab and Cancer Study at the University of Alabama

The University of Alabama is taking 3D printing education to a whole new level.  While many colleges and universities are primarily focusing this type of advanced technology for classwork instruction in engineering applications, UA is actually using it to help find a cure for cancer.

In February of 2014, the UA 3D Printing Lab unveiled its very first 3-dimensional model of the molecular structure of a G-quadruplex DNA sequence.  This model is already being used in many pre-clinical studies around the world in their attempts to find a cure for pancreatic and many other forms of cancer.  The DNA model is so intricately complex, constructed with numerous areas of stacked functional groups, that scientists were having an extreme difficult time in visualizing its genetic makeup.  Thanks to the UA 3D Printing Lab, that problem is solved forever.

The success of the UV model is attracting worldwide attention of both university administrators and future college’s students alike due to its proven unlimited possibilities that 3D printing education can transcend into any field of study.  This technology is no longer just for engineering enthusiasts any more.  Students who specialize in 3-dimensional printing now have proof that they will be able to find an infinite variety of 3D printing jobs available to them after graduation in nearly any area of expertise imaginable.

The Eight Fundamental 3D Printing Prep Functions

If you’ve watched a 3D model being printed on TV, it’s likely that you were amazed. That’s ok – it is an amazing thing! But they make it look as simple as easy as waving an object in front of the scanner and printer and then standing back in awe as a completely miniature model of The Whitehouse comes shuffling out. Hmmm. We hate to burst your bubble but it’s not quite that easy. If only...

If you have a 3D model that you want to print out, you might be interested to know what leads up to that final print. There are eight steps to prepping before printing.

Sizing

3D models often have to be resized before they can be printed. This could because it may not quite fit in the build volume of your printer or you could want to make the print as large as possible. This is the stage where plastic shrinkage has to be considered so the size of your print may have to be increased to account for that shrinkage.

Measurement

Quite often, it’s necessary to make sure that the print is a specific size. Some software will let you resize an object by stretching it. However, for a specific resize, you need a numerical way of requesting it. If you have no way of doing that, then you won’t have much idea of what the completed size will be.

Rotation

All 3D tools for modelling are not created equal. Some have the Y axis as the up or down and others have the Z axis for it. Crazy, we know. What this means for you is that if the model is on its’ side when you start to print, it’s not going to work. You’ll need to rotate the model 90 degrees so that the orientation is right. Free rotation tools aren’t great for this so you’re best to perform this rotation numerically.

Sealing

If a model has been obtained via 3D scanning, you may find unexpected holes that ruin the solid state of the finished article. Some software for slicing and printing can recognise a hole but how they see it might not be how you see it. You need a sealing tool to get those holes fixed before printing.

Placement

The virtual origin spot is vital to good 3D printing. All 3D models must have a position that is relative to this spot. This sweet spot makes sure that when you import the model into your slicing software, it is in exactly the spot you need so that it is on the print bed.

Cutting

Make sure that your prep-ping software can cut 3D models on each axis. This is necessary because sometimes a 3D model looks as if it is completely flat on the bottom but when you come to print it...it isn’t and it causes all sorts of issues. The simple fix is to use your prep-ping software to shave of a thin piece of your model’s bottom to make sure it’s really flat.

Viewing

Make sure that your software will let you zoom in and view your 3D model in rotation. This is so that you can take a good look at it from all the way round to see if it’s overhanging anywhere to the point where you may have to include some sort of support structure. Adding supports may take a little more time and a little more plastic but it saves you wasting a whole printed model that can’t support itself. Avoid fixed view software which doesn’t offer this function.

Copying

Now that you’ve seen how much work goes into preparing a 3D model for printing, you will understand why we advise you to make sure that your software will let you make multiple copies with one press of a button. 

The world of 3D printing hasn’t yet reached the point where one software package contains everything that’s needed. Most software's have a lot of functions but to get these essential eight, you may need to have more than one package on the go.

Dyson Award Winning BioPrinter Builds Skin Grafts On Demand

As of lately, there has been intense competition to perfection and petition medical technology based on 3D printing. Its produce range from body parts to printed lightweight casts, and both amateurs and institutions of all sizes are included amongst participants. In the endeavor to use 3D-printed skin to treat burns and lesions, another major contender that has been revealed is the US Army. However, considering that competition has crossed the US borders, an award-winning Canadian team has made the most recent contribution.

Arianna McAllister as well as Lian Leng, both engineering students from the University of Toronto, engineered the PrintAlive Bioprinter for the 2014 James Dyson Awards program. Consequently they won the first prize of $3,500, along with the opportunity to compete for $50,000 with 18 international teams from all over the globe. The non-profit James Dyson Foundation uses its annual award program to encourage and feature helpful and problem-solving industrial or product designs from students in the engineering and scientific fields.

The Toronto team has successfully addressed a twofold problem. First, damage to both the dermis and the epidermis, both containing various cells and structures, is often caused by severe burns. Therefore, specialized treatments are required. In cases like these, the body is not able to easily regenerate itself. To prevent fatalities, it is crucial to be able to close those wounds rapidly. The second issue that has been tackled by the team was the need to use 3D printers to produce flexible and skin-like materials, which would last during grafting procedures. Traditional 3D printers only work effectively with harder materials. Moreover, it has not been possible to structure skin grafts involving intricate layering of various cells.

The students worked together with the help of Boyang Zhang Dr. Marc Jeschke and Professor Axel Guenther to develop a printer cartridge that has never been developed before. Tiny channels are contained in this special cartridge, with a liquid environment containing skin cells filled inside those channels. Before printing, the dermis and epidermis cells, and that specialized liquid, are all kept in two different channels. The printing process dispenses a liquid form of the artificial skin into yet another liquid, until it solidifies into a gel. Then the printer prints the two solidified layers together, on top of each other, as a result of which a biodegradable dressing is generated, containing the skin cells required for treating deep skin wounds.

Until now, the grafts of human skin printed from the PrintAlive Bioprinter have been successfully used to heal wounds in immune-compromised mice. Soon, the team will hopefully be working in pigs using larger grafts, and after that human clinical trials will begin within 2 to 3 years. According to reports by the US army, clinical trials of the army’s own skin-printing technology will also begin this summer. All that remains now is the find out whether it will be the Canadian team that will surpass the US Army or vice versa, and in any case, both are striving for a common goal.

How autodesk helps create realistic, accurate 3D printable models

Nobody would have suspected that within such short period of 3D printing technology we would be experiencing such a revolutionary stride. Emergence of other disciplines like concerned with determining positions in geometry has enable any Autodesk user design and print 3d coral reef models. 

Challenges of previous methods

Previously researchers relied on 2D models to gain the visual outlook design and modelling. This is a tremendous achievement given previous attempts only achieved a 2D model. The hard part was in calculation of surface area and numerically computes it when designing such a natural mode. Efforts proved to be time intensive and exhaustive and limited in terms of the dimensional view.

Impact of Autodesk software

Autodesk is not only simplifying the design process but also ensuring high quality printouts that are the exact copy of the natural organism. Auto-desk recap offers a better automated method of not only accurately predicting growth of coral reefs but also provides a perfect platform to understand the diversity of these marvelous creatures. 

Importance of coral reef modelling.

Various phenomenon affect the ocean and organisms living in it, to fully assess the impact of calamities like global warming, underwater volcanic eruptions etc. We need a near perfect model of the real life coral reef. This hitherto to recent discoveries impact assessment of natural development, infections and bleaching on coral reefs was very limited.

Why assess the coral reef?

Statistics shows that despite corals occupying less than 1% of ocean it contributes natural habitat to 25% of organisms. This is such big factor in oceanography that it cannot be ignored easily. Another reason would be to provide a capable tool for academic and research work to scholars.

The design process using Auto-desk software.

This process starts with underground image captures for both corals and organisms living in them. This image is then uploaded to a computer with Autodesk installed. A model design then using Autodesk tool call recaps short for reality capture starts modelling the model using the picture as reference. A final model is then produced using a good quality 3D printer. 

What does the future look like?

Surely the strides made by Auto-desk Inc. are good enough but there is always room for improvement. I am imagining a scenario where picture upload to the software will be enough to produce the desired model design. Better still am also imagining a real life motion model of coral reef showing changes with respect to time or natural phenomena like sulphur pollution.
