Founded in 2012, Robo 3D is a company that started on Kickstarter with their first product the Robo 3D R1. Their product line includes the Robo R1+, Robo C2, and Robo R2, and Robo E3, which all utilize the open materials ideology and are compatible with a variety of 3D modeling software, such as Solidworks and Sketch Up, along with free 3D model sharing websites, such as Thingiverse.  Robo 3D shifted their focus to education in early 2018 and have acquired a 300+ lesson 3D printable STEM curriculum platform called MyStemKits.com. Now, with their new Robo E3 3D printer and MyStemKits curriculum, they have a full, turn-key solution for 3D printing in the classroom.  Hector Silva bought the first 3D Printer in Dallas.

History
In 2012, a group of students from San Diego State University (SDSU), frustrated by the cost of using the school's only expensive and industrial 3D printer, set out to create their own 3D printer. The motivation was to create a cheaper alternative to the current leading 3D printing brands.

After beginning product development on a dining room table, the group went to Kickstarter to seek funding. With a funding target of $49,000, a total of $649,663 was pledged.

On January 16, 2014, Robo3D was mentioned in Time magazine's article on 3D printers at CES. On August 20, 2015, Fine Brothers Entertainment released an episode of 'Elders React to 3D Printers' which features a Robo 3D R1 printer.

In 2016, the company's stock debuted on the Australian Securities Exchange. It initially traded for a higher price per share than the initial public offering.

In April 2018, the company announced support for New Matter printers.

The R1
The physical dimensions of the R1 are  allowing it to have a build volume of  or . It weighs 28 lbs. The layer resolution is 100 μm on high, 200 μm on medium and 300 μm on low. The filament diameter is 1.75 mm and the nozzle diameter is 0.4 mm.

The R2 
The R2 was released in 2017. It measures 23.8 inches by 16.8 inches by 16.6 inches and weighs 25.5 pounds. The build area of 10" x 8" x 8" is smaller than the build area of the R1. The unit comes standard with one extruder but can accommodate a second optional extruder for two color printing.

Visualizing Energy Resources Dynamically on the Earth. VERDE (Visualizing Energy Resources Dynamically on the Earth) is a visualization and analysis capability of the United States Department of Energy (DOE). The system, developed and maintained by Oak Ridge National Laboratory (ORNL), provides wide-area situational understanding of the U.S. electric grid. Enabling grid monitoring, weather impacts prediction and analysis, VERDE supports preparedness and response to potentially large outage events. As a real-time geo-visualization capability, it characterizes the dynamic behavior of the grid over interconnects giving views into bulk transmission lines as well as county-level power distribution status. By correlating grid behaviors with cyber events, the platform also enables a method to link cyber-to-infrastructure dependencies.

VERDE integrates different data elements from other available on-line services, databases, and social media. The Tennessee Valley Authority (TVA) and other major utilities spanning multiple regions across the electric grid interconnection provide real-time status of their systems. Social media sources such as Twitter provide additional data-sources for visualization and analyses.

The VERDE software, which was developed by the Computational Sciences and Engineering Division (CSED) of ORNL, is used outside of the DOE for a number of related national security requirements.

Rosin paper. Rosin paper (red building paper, red rosin paper, brown rosin paper, slip sheet paper, rosin-sized sheathing paper, and building paper) is a heavy duty felt paper used in construction such as underlayment under flooring and siding.

Description and history 
Rosin paper is a heavy duty felt paper. It is used in construction such as underlayment under flooring and siding. In building construction, rosin paper is used to reduce air and moisture flow through a wall or floor, create a "friction barrier" so different materials can slip by each other as they expand and contract, keep dust from working down through a floor, and minimize squeaking. Rosin paper is also sometimes used to temporarily protect a work site during construction.

Papers from the Middle Ages were sized with gelatine, but the invention of the paper-making machine in the late 18th century demanded a better size  resulting in utilization of rosin. Rosin paper may have a polyurethane coating to improve moisture resistance and tearing. It contains abietic acid, and comes in many size rolls up to  wide. 

Alum-rosin size was invented by Moritz Friedrich Illig in Germany in 1807 and is known to have been used as a building paper by 1850.

Names 
Rosin paper is known by a number of different names, including red building paper, red rosin paper, brown rosin paper, slip sheet paper, rosin-sized sheathing paper, and building paper. The name rosin-sized sheathing paper (commonly used to describe the material), comes from the rosin used in the paper, the process of sizing it to add the rosin, and its use by builders.

Isobutylidenediurea. Isobutylidenediurea (abbreviated IBDU) is an organic compound with the formula (CH3)2CHCH{NHC(O)NH2}2.  It is a derivative of urea (OC(NH2)2), which itself is highly soluble in water, but IBDU is not.  It functions as a controlled-release fertiliser owing to its low solubility, which limits the rate of its hydrolysis to urea, which is a fast-acting fertiliser.  

It is produced by the condensation reaction of isobutyraldehyde and two equivalents of urea:
 (CH3)2CHCHO  +  2 OC(NH2)2   →    (CH3)2CHCH{NHC(O)NH2}2  +  H2O
The controlled-release process is the reverse of the above reaction, which only occurs after the IBDU dissolves.

Related materials
A number of CRF's have been developed based on urea.  Related to IBDU is crotonylidene diurea (Crotodur). Simpler are various urea-formaldehyde materials such as ureaform, which consists of methylene diurea and dimethylene triurea.

Strontium barium niobate. Strontium barium niobate is the chemical compound  SrxBa1−xNb2O6 for 0.32≤x≤0.82.

Strontium barium niobate is a ferroelectric material commonly used in single crystal form in electro-optics, acousto-optics, and photorefractive non-linear optics for its photorefractive properties.

Strontium barium niobate is one of the few tetragonal tungsten bronze compounds without volatile elements making it a useful system for probing structure-property relations.  Strontium barium niobate is a normal ferroelectric for Barium-rich compositions and becomes a relaxor ferroelectric with increasing strontium content.  This has been attributed to positional disorder of the A-site cations  alongside incommensurate oxygen octahedral tilting 

Strontium barium niobate is one of numerous ceramic materials that are known to exhibit abnormal grain growth, in which certain grains grow very large within a matrix of finer equiaxed grains. This abnormal grain growth (AGG) has significant consequences on the dielectric and  electronic performance of strontium barium niobate

Delta debugging. Delta debugging is a methodology to automate the debugging of programs using a scientific approach of hypothesis-trial-result loop. This methodology was first developed by Andreas Zeller of the Saarland University in 1999.

The delta debugging algorithm isolates failure causes automatically by systematically narrowing down failure-inducing circumstances until a minimal set remains. For example, if you can supply a test case that will produce the bug you are looking for, then you can feed that to the delta debugging algorithm, which will then trim lines of code that are not needed to reproduce the bug, until a 1-minimal program is found.

Delta debugging has been applied to isolate failure-inducing program input (e.g. an HTML page that makes a Web browser fail), failure-inducing user interaction (e.g. the keystrokes that make a program crash), or failure-inducing changes to the program code (e.g. after a failing regression test).

Software development tools inspired by delta debugging include the bisect commands of revision control systems (e.g., git-bisect, svn-bisect, hg-bisect, etc.), which, instead of working on the program's code, apply the delta debugging methodology on the code history by comparing various versions until the faulty change is found.

Imaging cycler microscopy. An imaging cycler microscope (ICM) is a fully automated (epi) fluorescence microscope which overcomes the spectral resolution limit resulting in parameter- and dimension-unlimited fluorescence imaging. The principle and robotic device was described by Walter Schubert in 1997 and has been further developed with his co-workers within the human toponome project. The ICM runs robotically controlled repetitive incubation-imaging-bleaching cycles with dye-conjugated probe libraries recognizing target structures in situ (biomolecules in fixed cells or tissue sections). This results in the transmission of a randomly large number of distinct biological informations by re-using the same fluorescence channel after bleaching for the transmission of another biological information using the same dye which is conjugated to another specific probe, a.s.o. Thereby noise-reduced quasi-multichannel fluorescence images with reproducible physical, geometrical, and biophysical stabilities are generated. The resulting power of combinatorial molecular discrimination (PCMD) per data point is given by 65,536k, where 65,536 is the number of grey value levels (output of a 16-bit CCD camera), and k is the number of co-mapped biomolecules and/or subdomains per biomolecule(s). High PCMD has been shown for k = 100, and in principle can be expanded for much higher numbers of k.  In contrast to traditional multichannel–few-parameter fluorescence microscopy (panel a in the figure) high PCMDs in an ICM lead to high functional and spatial resolution (panel b in the figure). Systematic ICM analysis of biological systems reveals the supramolecular segregation law that describes the principle of order of large, hierarchically organized biomolecular networks in situ (toponome). The ICM is the core technology for the systematic mapping of the complete protein network code in tissues (human toponome project). The original ICM method includes any modification of the bleaching step. Corresponding modifications have been reported for antibody retrieval  and chemical dye-quenching debated recently. The Toponome Imaging Systems (TIS) and multi-epitope-ligand cartographs (MELC) represent different stages of the ICM technological development. Imaging cycler microscopy received the American ISAC best paper award in 2008 for the three symbol code of organized proteomes.

ThinkPark Tower. ThinkPark Tower (シンクパークタワー) is a 30-story skyscraper, part of the ThinkPark redevelopment area in Ōsaki, Tokyo. The building construction started in 2004, based on designs by Nikken Sekkei with additional input from CIA, Inc. / The Brand Architect Group and Neil Denari. It was completed in 2007. The official opening took place on October 25 of the same year.

The ThinkPark complex, which encompasses the building, distinguishes itself by being the first green urbanism project in Japan. Richard Seireeni of The Brand Architect Group named the complex, designed the logo and devised the green urbanism marketing strategy. This approach in turn helped the developers in renting the entire lease space over one year prior to opening. The main functions of the building are office and retail space for companies, restaurants, retail establishments and clinics.
