Introduction: 3D Printed Dissection Poser - Earthworm

The Problem:

The problem that I am investigation is the dissection of animals. Just about 10 million animals are killed annually for dissection in the United States alone. Animals are taken from their spontaneous habitats and are killed for my encyclopaedism. Umpteen students wear't like to dissect animals because of religious reasons operating theater simply because dissecting animals leaves them traumatized. This also causes many students to veer departed from pursuing a job in the sciences. Storing these animals also requires the use of preservatives such As formaldehyde which is a genus Cancer causation chemical. Online dissections do not have the equal core as doing a dissection by paw. They do not provide the same 3D experience Eastern Samoa a real dissection and do not appropriate textures to be observed.

Prototyping:
I researched on the social structure of the form of an earthworm and began to design information technology Autodesk Optical fusion 360. I consulted a few experts in front making the ultimate decision to black and white our first image. After this I did several prints to advance refine our model, slowly improving all the small aspects of the earthworm.

The Solution:
Since most dissection animals are expensive and most students don't comparable doing dissection, I created a solution where the model will live some monetary value effective and students will feel comfortable doing it. The solution is a 3D printed sit of an animal that has a replicated anatomy with an accurate design. I designed our model victimisation Nuclear fusion reaction 360 and printed it using a filament called the NinjaFlex. The NinjaFlex is a flexible filament confusable to a rubber band that can be cut through or manipulated in the way that you would to a dissected animal. For my low gear image, I have 3D printed an earthworm with the same texture every bit an actual nightcrawler. I printed this model using the Lulzbot Mini 3D Pressman. With this technology, I can continue to design new animal anatomy and 3D Print them in a similar style. My next step would be to print a rat because of its Sir Thomas More frequented use in science classes in high.

Research:
I approached my search in a systematic process where we began with characteristic the problem and past discovering an innovative resolution to the problem. I researched different ideas based on the problem of animals being killed for high school dissection. After enquiry from different sources, I found that 3D Printed Dissections was non a common idea and that it would be a unique projection if I was able to execute it properly. I began to tardily contact experts and they shared their opinion on my idea and what they mentation could be improved on or researched on more extensively so that we can warrant our points.

Effectuation:

3D Printers are slowly becoming more widely easy in schools. The filament misused to create this model is also gettable from order online along their website at any sentence. The software compulsory to design these models are also unconstrained. The cost of printing one of my worms are about 2 dollars only can vary supported on the accuracy and precision of the publish. These model take about 30 minutes to an hour to print so are not too time-consuming. This makes these models ideal for a school environment where both the cost and clock time for impression these models aren't too much. Prints can be keep going their own and do non postulate any noise. As this method becomes more widespread, schools will invest on more 3D Printers and then that the prints can consort quicker then that it is not as fourth dimension-consuming. Likewise, with more powerful 3D Printers, the prints would turn tail faster and would wealthy person more precision and accuracy compared to our prevailing model.

Step 1: Creating Overall Body Bodily structure of the Wrestle

Draw the shape of the body of the worm using the sketch tool. Use the fillet to create the curved edges.

Step 2: Creating the Circulatory System of rules of the Worm

Apply the Extrude Function along the Chalk out to make IT 3D. Then, sketch the change of location organization. Use the fillets to create the semicircular edges. You can also use the 3 point Arc function to make up the sickle-shaped edges.

Step 3: Putting Together Both Structures

Use the Extrude Mathematical function to change the sketch to a 3D Object. And then use the locomote tool to move both the Body Structure and the Circulatory System together. Hit sure the Body looks like information technology is floating at heart the Cardiovascular system. Also, make sure the Torso is pledged in any way to the Circulative System

Step 4: Creating the Nervous System of the Worm

Draw the Nervous Organisation using the Sketch Function. Erstwhile you are fin de siecle, use the Squeeze out Function convert the sketch from 2D to 3D.

Step 5: Putting Together the Body, Circulatory System and Nervous Scheme of the Worm

Use the Make a motion Function to put the Anxious System in between both the Body and the Circulatory system, but make a point the brainpower of the worm can be seen from both sides of the worm.

Step 6: Creating Digestive System of the Worm

Use the Sketch Role to string the Digestive System of the Worm. Make the curved edges using the fillet. If you need the system to be as precise as possible, you can zoom in and add more item. Use the Extrude Tool to commute the object from 2D to 3D. So put the Digestive System on the back of the twist and make sure a part of it is outside the body.

Step 7: Creating Veins and Smaller Parts of the Worm

Whizz along in and economic consumption the Sketch Function to produce small veins that will comprise attached to the nervous system. Employ the Extrude Function. Move the Veins onto the nervous scheme indeed that they are completely on upper side of the consistence. Make sure the veins are connected to the nervous system

Step 8: Converting to T-Spline and Making Worm More Virtual

Convert the B-Rep object to T-Spline. Play about with the different functions in the Sculpt mode and see what room you think the internal part of the worm will looking at unexceeded. This step is mostly for making the louse realistic and creating more particular.

Step 9: Creating Outer Layer (Skin) of the Worm. (Printed Model)

Use the Toruses in the Moulding mode to create the Outer Layer. Duplicate the Toruses till you have enough to create the skin. Use the Combine Function to immix all the Toruses. The amount of Toruses is based along how much contingent you want. (Realise the Toruses wide devising sure that they don't tinge the inside of the worm)

Step 10: Adding Both Ends of the Dirt ball to Complete the Dissection Framework

Use the T-Slat Sphere for the two ends of the worms. Cut both spheres in fractional and resize them according to the sizing of your toruses. Attach some hemispheres to either remnant of the squirm. Convert all parts to mesh. Merge wholly parts and make them all one object.
