Rapid Prototyping is a process of manufacturing which finds a wide range of applications in the field of mechanical, industrial, aerospace and also in the electronics. Now-a-days due to their ease in the manufacturing of different materials and also the less time required for manufacturing and also some other advantages, they are being used in the field of medical and dentistry. Replacing the spine for humans or using biomaterials for support in the spinal cords is a place where rapid prototyping could be used for the manufacturing of those biomaterials. Spine is the backbone that encloses and also houses the spinal cord and protects them. There are various reasons that causes the fracture in the spine of the humans and this results in serious consequences to the spinal cord and also affects the human body from many doing operations. Some of the materials could be used for support in the human spine in case of injury and they can be used to replace the spine in case of some serious fractures and they should possess the properties and the strength to bear the weight and also to withstand the body conditions like temperature, pH level and also should protect the spinal cord effectively with a longer life Polymethyl methacrylate (PMMA) is a reliable biomaterial that could be used for the replacement and also for support for spine in the humans to withstand the weight and the body conditions and have a longer life. The rapid prototyping is a reliable method to manufacture the Polymethyl methacrylate (PMMA) to make the model of the human spine into the product. The model of the human spine could be made in some 3D modeling software’s and they can be also analyzed with some suitable software before manufacturing. The integration between the modeling software and the rapid prototyping machine could be done before the manufacturing and by this method the injuries in the spine could be rectified in a cheaper and effective way.

It was found that the human spine could be replaced by a spine made of Polymethyl Methacrylate (PMMA) in case of damage or disintegration to the human spine due to any accidents or disorders, as they can bear the load for a long time that is applied onto them. The PMMA material has a longer life and they are non-toxic in nature and this makes them suitable and reliable for their use in the human body. The PMMA material maintains the homeostasis of the temperature, pH level, etc., in the human body for a longer period of time. The manufacture of the PMMA human spine can be donewith the FDM machine which is integrated to the modelling software. The Fused Deposition Modelling (FDM) process manufactures the product in an easy manner in less time with high accuracy. The produced PMMA spine resists corrosion and erosion and they can be implanted inside the human body by suitable surgeries.
