Interlog Corporation has invented Multiple Material Additive Manufacturing Technology (MMAMT) based on our proprietary methods. The MMAMT uses a unique, precision instantaneous energy generation mechanism that quickly and easily constructs multiple-material (metal- and ceramic- as well as polymer-feedstock) structures/components with a very strong bond and with precision at the micron level.
The proprietary MMAMT energy process has a new design of printing head structure for multifold printing of different types of materials in an integrated form, which quickly and smoothly streamlines the printing process with minimal operator tending time. All design components are simulated and optimized in the design process. Models and parameters are validated thorough various methods.
The Interlog Corporation team has in-depth experiences with finite element analysis (FEA)/simulation for various physics and engineering applications, especially coupled phenomena or multi-physics.
Interlog Corporation is developing a new advanced textile manufacturing method based on Virtual-weaving Swift Textile Printing (V-STEP) technology. The V-STEP seamlessly produces woven-like garments quickly and inexpensively through virtual weaving (VW) – printing cross-sectional layers of a complex weaving or knitting structure along a printing path. The V-STEP allows to accelerate fabrication speed by folding a garment in the design process, printing the garment folded, and then unfolding the garment once the printing is completed. The V-STEP selectively infuses different types of material to build a hybrid textile in the VW process in parallel; for example, adding nano-particles to provide nano-fabric features such as stain-resistance, self-cleaning, and anti-bacterial properties (nano-particle infusion).
Interlog applies new computational schemes for Integrated Computational Materials Engineering (ICME) for the development of high strength steels with weight reduction. The team has developed well-established computational and experimental methodologies for a suite of material constitutive models (deformation and failure), manufacturing process and performance simulation modules, a properties database, as well as the computational environment linking them together for both performance prediction and material optimization. ICME has many fundamental issues related to stochasticity of processes and uncertainty of data, models, and multi-scale modeling chains in decision based design. For example, designing a material process contains various sources of uncertainty such as
1) natural uncertainty as a system variability, 2) model parameter uncertainty as a parameter uncertainty, 3) model structural uncertainty as a model uncertainty, and 4) propagated uncertainty as a process uncertainty. Uncertainty is a first order concern in the process of simulation-supported, decision based materials design. Uncertainty quantification in ICME is very difficult because the large range of equations in solving field equations involves nonlinear, time-dependent, multi-physics behavior of materials, including constraints, boundary/side conditions, jump conditions, thresholds, etc., which may vary from group to group. Moreover, experimental measurements are usually limited, and properties must be estimated from a limited amount of data.
Interlog Corporation develops a new Uncertainty-Quantification for Modal Parameters and Metrics (UMPM) methodology based on modified nonparametric resampling with nondeterministic uncertainty generalization (or quantification). The UMPM addresses what uncertainty is in a target model (or algorithm) in a comprehensive manner: i.e., uncertainty quantification (UQ) for the model without interfering an ICME process.
Interlog has considerable expertise in developing custom solutions for challenges in 3D printer Systems, Optical Systems, Machine Vision, Autonomy, Human-Machine Interface, Mobile Robotic Manipulation, and Inspection, as well as Electromechanical System Design. For example, our team designed and fabricated a remote telemanipulator that consists of 1) a master with an ergonomic operating handle, 2) a slave arm with an end-effector, 3) a table fixture, which is for noninvasive remote operation such as surgery and other hazardous material handlings.
Interlog has expertise in design and manufacturing a ultra-high resolution image / video system for various applications to military and industries. We are capable of design and fabricating precision optical and optoelectronic devices not only for visible spectrum but also thermal and night vision.
Interlog applies the latest research in computer, behavioral and learning sciences, game design, engineering, and mathematics, to develop innovative solutions for the physically-challenged in education, in training and performance enhancement. We are leaders in creating assistive device technology for the blind/visually impaired(BVI).
To address BVI needs for assistive devices for reading, writing, and to draw visually enriched objects, Interlog has worked on tactile display technology that interacts to displays any visual content tactilely (pictures, graphs, equations, Braille/Nemeth codes, etc.) using physical stimulation as vibration.
Interlog's technology produces not only tactile stimulation but also senses/displays physical input (type, handwriting, sketch) on the screen. BVI users can read, write, and describe any object by touch. For example, a user can read/write mathematical equations.
