Reverse engineering is a process of using 3D geometric modeling method to reconstruct actual object's CAD model based on these points, which is used physical digital measuring equipment to measure the three-dimensional coordinates of points on the surface of the object accurately and rapidly. Based on reverse engineering technology as the theoretical basis, the paper used three-coordinate measuring machine to measure ashtray surface data. After data was be handled, which was used to reconstruct 3D entity in Pro/E software. Last, the 3D entity of ashtray was printed out through rapid prototyping machine, which can be achieved by physical sample to rapid manufacturing of products, shortening production cycle, reducing production costs.

The present study focuses on the production, evaluation and comparison of prosthetic leg manufacturing using the rapid prototyping technology by implying the layer deposition technique with that of the traditional assembly manufacturing. By considering various process parameters such as the durability of the structure, the material, time of unit production and cost of manufacturing, it is found that despite the fact that the time and cost of manufacturing the prosthetic leg is substantial when compared to the traditional assembly manufacturing, due to greater user dependent customization and along with the high choice of materials and ability to fabricate the complex NURBS curves easily with the layer deposition and given the scope for on demand manufacturing, future estimation of parameters rapid prototyping has shown the conceivable possibility, yet required time modification when compared to SLA.

Polylacite (PLA) is a bioresorbable polymer with potential application for bone tissue repair;however, low heat distortion temperature (HDT) limits its biomedical applications. Due to the low-melting point of PLA, only fused deposition modelling (FDM) was used as a rapid prototyping technology to form PLA products. Here, the work presents a PLA stereocomplex formation which was facilitated by melt blending PLA and poly(D-lactide). The melting point was successfully increased to 219.2 degrees C. Besides, the PLA stereocomplex-based three-dimensional scaffold was formed by selective laser sintering (SLS). The parameters of SLS (energy density, scan speed, scan spacing, preheating temperature etc.) were also optimised by comparing the microstructure. Compared with the FDM, the SLS provides many benefits for fabricating tissue engineering scaffolds due to its rough powder surface. Results show that the PLA stereocomplex was successfully obtained and crystallinity of the stereocomplex was 59.7%.

Objective: To investigate the application of individual digital resection plate in the treatment of bone tumor. Methods: Twenty-three patients with bone tumor by spiral CT scanner and MRI. The data was reconstructed by 3 D imaging reconstruction workstation. The operation was simulated and the individual resection plate was designed on the virtual 3 D model according to the surgical procedure. With the rapid prototyping technology, the individual resection plate was produced to guide the reduction of the bone tumor. Results: The average follow-up times were 48 months. No local recurrence, endoprostheses infection, loosening and fracture happened. Average scoring was 21 points according to Enneking system. Conclusion: Individual digital reduction plate is helpful in accurate reduction of bone tumor and can also save the operation time.

Biomaterial-based bone graft substitute with favorable mechanical and biological properties could be used as an alternative to autograft for large defect treatment. Here, an apatite collagen polycaprolactone (Ap-Col-PCL) composite construct was developed with unique nano micro macro hierarchical architectures by combining rapid prototyping (RP) fabrication technology and a 3D functionalization strategy. Macroporous PCL framework was fabricated using RP technology, then functionalized by collagen incorporation and biomimetic deposition. Ap-Col-PCL composite construct was characterized with hierarchical architectures of a nanoscale (similar to 100 nm thickness and similar to 1 mu m length) platelike apatite coating on the microporous (126 +/- 18 mu m) collagen networks, which homogeneously filled the macroporous (similar to 4000 mu m) PCL frameworks and possessed a favorable hydrophilic property and compressive modulus (68.75 +/- 3.39 MPa) similar to that of cancellous bone. Moreover, in vitro cell culture assay and in vivo critical-sized bone defect implantation demonstrated that the Ap-Col-PCL construct could not only significantly increase the cell adhesion capability (2.0-fold) and promote faster cell proliferation but also successfully bridge the segmental long bone defect within 12 weeks with much more bone regeneration (5.2-fold), better osteointegration (7.2-fold), and a faster new bone deposition rate (2.9-fold). Our study demonstrated that biomimetically ornamented Ap-Col-PCL constructs exhibit a favorable mechanical property, more bone tissue ingrowth, and better osteointegration capability as an effective bone graft substitute for critical-sized bone defect treatment;meanwhile, it can also harness the advantages of RP technology, in particular, facilitating the customization of the shape and size of implants according to medical images during clinical application.

In this paper, the construction of phantom mimic vessel is presented to diagnose the Deep Vein Thrombosis (DVT). The diagnosis of DVT is commonly used by monitoring the blood velocity and present of thrombus in vessel from B-mode ultrasound image associated with the application of Doppler ultrasound. Since it is difficult to recognize the vessel condition at the early stage of DVT, this study is to assess the vessel behavior at the early stage of DVT using phantom experiment. The phantom size and elasticity is considered to be the important parameters in constructing the phantom mimic vessel. rapid prototyping technology and solid works are used in constructing the phantom.
