  • Hybrid packaging of a monolithic multi-sensor

    In order to satisfy the different packaging requirement of individual sensors in the monolithic multi-sensor chip, a hybrid packaging method is presented in the paper. The packaging method of multi-sensor makes use of high-resolution stereolithography system of photopatternable resin constructing the main packaging structure in the way of batch production, low cost and good resolution. A monolithic multi-sensor which consists of three-axis accelerometer, absolute pressure sensor and temperature sensor is encapsulated by the hybrid packaging method. The hybrid packaging structure which is composed of the packaging ring, silicon cap, silicone sealant and soft silicone gel, can simultaneously provide direct interaction between pressure sensor and the pressure variable to be measured as well as keep hermetic insulation for accelerometer and mechanical protection for the temperature sensor and all electrically components in the multi-sensor chip. The packaging ring which is the most important part in the hybrid packaging structure is fabricated by using high-resolution stereolithography system of photopatternable resin. At last the measure results show the hybrid packaging method is appropriate for the package of the monolithic multi-sensor chip. It has potential to be applied to a variety of multi-sensor.

  • Design and Preparation of Carbon Template with Tailored Porous System

    A mold with tailored network structures was fabricated by stereolithography. A carbon template was prepared using the mold, which was filled with a mixture of phenolic resin and starch powder, and then pyrolyzed in a nitrogen atmosphere. Thermo-gravimetric analysis was applied to study the pyrolysis behaviors of photo-curable resin, phenolic resin and starch. X-ray diffraction Fourier Transform Infrared Spectroscopy and scanning electron microscope were employed to analyze and identify the phase and microstructures of the carbon templates. Open porosity and density of the carbon templates were measured by Archimedes principle. The result shows that the carbon template is noncrystalline material and has a turbostratic structure, containing few C-H bonds. Crystalline order increases with increasing pyrolysis temperature. The porous system includes channels, large pores (d=10-50μm) and small pores (d=l-3μm), this make it possible to fabricate thick wall components without cracks.

  • Research on Recoating Process in High-Resolution Stereolithography System

    To resolve the problem that thickness of resin layer increases with the object height during building process in piston recoating system, experimental investigations were performed to establish the model describing the relationship of recoating layer thickness with object height and blade speed by using response surfaces methodology. According to the model, a novel recoating process with dynamically optimized blade speed is proposed. Verifying experiment results show that the problem that the thickness of resin layer increases with the height of objects is solved, and experiment results indicate that the new recoating process reduces the difference between maximum and minimum thickness of resin layer from 27 mum to 6.9 mum, and experiment results also demonstrates that step position error is reduced from 494 mum to 66 mum. The new recoating process provides an effective way for high- resolution SL system to improve the building accuracy, and the new recoating process can also be applied to current recoating system, so it is important for SL system to improve building accuracy in Z direction with the new recoating method.

Though lots of current slicing algorithms all focus on minimizing the tolerance, they all overlook the importance of tolerance uniformity. This often results in the problems of shape distortion. Therefore to ensure unilateral tolerance on whole parts for all slicing type, a new slicing procedure is developed to adaptive adjust slicing height according to the unit normal vector of a share edge between triangle facets in stereolithography (STL) file. Experiments show the algorithm not only effectively and reliably slicing the STL model but also improving parts' working tolerance

  • Molecules at your fingertips

    Chemists learn about chemical and biological reactions by studying the interactions between molecular structures. A molecule's shape and its fit with other structures offer clues to its purpose and suggest ways it can be modified to create new reactions. Molecular modeling software lets chemical engineers view 3D models of these structures on screen. But it still can be difficult to grasp the shapes of a complex model this way. And now try to imagine: what would a blind chemist do? A team in the Department of Chemical Engineering, Chemistry, and Environmental Science at the New Jersey Institute of Technology (NJIT) in Newark decided to apply the rapid prototyping process of stereolithography to produce highly accurate 3D plastic models of molecular structures. One of the team members, William J. Skawinski, a postdoctoral research associate, started to go blind from a degenerative condition while still in college. Skawinski and his research partner, chemistry professor Carol Venanzi, received a $360,000 grant from the National Science Foundation to investigate the technique of creating molecular models for blind students. But like other innovations originally developed for disabled persons (curb cuts for wheel chair users come to mind), many more people will benefit from the project than the visually disabled population.<<ETX>>

  • Strategies for Creating Cardiovascular Models with Digital Light Projection Stereolithography

    Stereolithography (SLA) represents an additive manufacturing method that uses light to selectively cure a photoresin for the purpose of creating a 3 dimensional structure. With successively cured layers, large geometry (4" x 6" x 15") can be achieved with incredibly high resolution (~100 micrometer). Using a digital light projection (DLP) chip, whole layers of the model can be cured in a single step as opposed to laser based methods that require the laser to line scan the model. This approach rapidly accelerates the printing process, while still maintaining a high level of accuracy in the part. The goal of this printer is to produce models of the cardiovascular system for benchtop flow studies. With many of the intended models being complex in nature, fused filament printing would not produce the needed resolution or finish required. The challenge with many models is how segment the model for printing, curing settings, and how to position the geometry on the print bed. Different photoresin chemistry's were used achieve specific model objectives, reusable molds, dissolvable molds, and device prototypes. The underlying chemistry, printing strategies, and discussion of the tested solutions to problems with this technology will be covered. With the growing presence of DLP SLA, many of the challenges with this method are limiting the success of these designs in the marketplace. This presentation will cover the advances made with the current design and the benefits this technology has for this application.

  • Lower your time to market with StereoLithography

    Today the winners in the electronic industry are those companies that reach the marketplace first with quality products and lower production costs. In just a few short years, one technology has revolutionized this process StereoLithography. StereoLithography is a process which quickly produces accurate three-dimensional parts without machining, cutting, or tooling. The StereoLithography process directs a computer-controlled laser beam to draw cross sections of an object on the surface of a vat of liquid plastic. The plastic hardens only where touched by the laser, forming one cross-sectional layer. The cross section is lowered by an elevator into the vat and the process is repeated, each layer adhering to the last, until a three- dimensional part is formed. Using this technology, CAD/CAM design of parts can be directly transformed into patterns in a matter of hours.

  • The Rapid Foundry Tooling System: a cutting-edge computer-aided design system

    The Rapid Foundry Tooling System incorporates cutting-edge computer technology. A new computer technology called the Episodal Associative Memory (EAM) uses computers to collect and organize design and manufacturing knowledge in the form of individual design and analysis episodes. When properly organized and provided as reference, this collection of knowledge is then used to solve new problems. The capture of design and fabrication knowledge in the form of episodes provides easy access to vital information. The EAM also provides a powerful method to organize this information for use in support of new design and fabrication tasks. The Rapid Foundry Tooling System has been shown to provide unique and useful capabilities in support of the design of sand castings and molds for these castings.<<ETX>>

  • Design and manufacture of a wax injection tool for investment casting using rapid tooling

    A rapid wax injection tool of a gearbox shift fork was designed, simulated, and manufactured using rapid prototyping and rapid tooling technology to save time and cost of producing wax models used for the investment casting process. CAE simulation softwares, in particular, MoldFlow, are used to get wax injection moulding parameters such as filling parameters, temperature profiles, freeze time, speed, and pressure. The results of this research were compared with conventional wax model production methods. The criteria of such comparison were based upon parameters such as time, cost, and other related characteristics, which resulted in saving of 50% in time and 60% in cost. In this research, design, assembly, and wax injection operation of the wax tool took 10 days. Considering the fact that wax melting temperature is as low as 70°C and injection pressure of 0.5 MPa, the tool suffers no damage due to the thermal and pressure stresses, leading to the mass production of wax models.
