Objet Geometries

Objet Geometries is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Objet Geometries rather than just read about it. In short: Objet Geometries is one of the brands of Stratasys, a 3D printer developing company. The brand began with Objet Geometries Ltd, a corporation engaged in the design, development, and manufacture of photopolymer 3D printing systems.

Key takeaways

Objet Geometries belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Objet Geometries to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Objet Geometries from memory before moving on to harder problems.

Reference excerpt

Objet Geometries is one of the brands of Stratasys, a 3D printer developing company. The brand began with Objet Geometries Ltd, a corporation engaged in the design, development, and manufacture of photopolymer 3D printing systems. The company, incorporated in 1998, was based in Rehovot, Israel. In 2011 the company merged with Stratasys. It held patents on a number of associated printing materials that are used in PolyJet and PolyJet Matrix polymer jetting technologies. It distributed 3D printers worldwide through wholly owned subsidiaries in the United States (Objet Geometries Inc), Europe (Objet Geometries GmbH), and Hong Kong. Objet Geometries owned more than 50 patents and patent-pending inventions.

History Objet was founded in 1998 by Rami Bonen, Gershon Miller and Hanan Gothait. In September 2000 it announced the completion of a second private placement, securing it $15 million at a post-money company valuation of $36 million. Participants in this round were the Templeton Foreign Fund, private investors from Europe and the United States and Scitex Corporation, which acquired an initial 18.7% stake in the company, which was subsequently increased. In June 2005, Scitex sold all its interest, then standing at 22.9%, to the other shareholders of Objet for $3.0 million in cash.

Merger with Stratasys On April 16, 2012, Objet announced that it agreed to merge with Stratasys, a leading manufacturer of 3D printers; in an all-stock transaction. Stratasys shareholders were expected to own 55 percent and Objet shareholders were expected to own 45 percent of the combined company. The merger was completed on December 3, 2012. The market capitalization of the new company was approximately $3.0 billion.

Technology

The Polyjet Matrix 3D printing technology uses simultaneous jetting of multiple types of modeling materials to create a single piece 3D model. PolyJet is used by automotive, electronics, consumer goods, medical development, and clothing manufacturers, as well as for creating 3D models for use in movies such as Coraline. The Eden line of 3D Printing Systems and the Alaris30 3D desktop printer are based on the PolyJet technology. The Connex family of 3D printers are based on PolyJet Matrix technology, which jets multiple model materials simultaneously and creates composite Digital Materials on the fly. All Objet systems use FullCure polymers.

Partnerships Objet Geometries has partnered with SolidWorks to interface their computer-aided design software with Objet’s Connex500 system. The co-developed software add-in allows significantly more control over end to end modelling preferences.

Worked examples

Example 1 — a first encounter with Objet Geometries

Start with the simplest possible case. Write down what Objet Geometries claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Objet Geometries before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Objet Geometries ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Objet Geometries

In research: Objet Geometries appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Objet Geometries in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Objet Geometries is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1998 establishments in Israel, 3D printer companies, Companies established in 1998, so understanding it makes those chapters shorter.
In everyday life: Look for Objet Geometries outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
