Solid Concepts 1911 DMLS

Solid Concepts 1911 DMLS is a 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 Solid Concepts 1911 DMLS rather than just read about it. In short: The Solid Concepts 1911 DMLS is a 3D printed improvised firearm version of the M1911 pistol. It was made public around November 2013 and was printed via the direct metal laser sintering (DMLS) method.

Key takeaways

Solid Concepts 1911 DMLS belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Solid Concepts 1911 DMLS to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Solid Concepts 1911 DMLS from memory before moving on to harder problems.

Reference excerpt

The Solid Concepts 1911 DMLS is a 3D printed improvised firearm version of the M1911 pistol. It was made public around November 2013 and was printed via the direct metal laser sintering (DMLS) method. It was created by Solid Concepts. The first gun, version 1.0, is made up of 34 3D-printed 17-4 stainless steel components.

Design

The 1911 DMLS weighs 2.25 pounds (1.02 kg) when it is empty i.e is not filled with a magazine and the trigger pull weighs 5 pounds-force (22 N). The width is 1.3 inches (33 mm) wide. The sight radius is 6.4 inches (160 mm) and consists of a standard GI with a square notch rear. The ratio of the twist is 1:15.8; at 6=Lands 6=Grooves. The gun used Inconel 625 (a nickel-chromium alloy) material and stainless steel via the Direct Metal Laser Sintering method. The Solid Concepts Browning M1911 replica, version 2.0, will be composed of 34 Inconel 625 components, (not including grips). The two carbon-fiber filled nylon 12 grips were also 3D printed. Unlike early 3D printed plastic guns, the barrel of the 1911 was rifled. None of the parts were machined during production, and assembly took less than seven minutes once the parts had been filed and hardened.

Printer The German EOSINT M270 Direct Metal 3D Printer used to create the weapon cost between $500,000 to $1,000,000 at the time the gun was created as of November 2013 and uses a commercial-grade power source. The printer requires argon and nitrogen gas.

Capability and firing tests According to Sky News, during the initial test Solid Concepts stated: "It functions beautifully. Our resident gun expert has fired 50 successful rounds and hit a few bull's eyes at over 30 yards (27.43 metres)". The Solid Concepts Pistol fired its 5000th round on 6 September 2014.

Worked examples

Example 1 — a first encounter with Solid Concepts 1911 DMLS

Start with the simplest possible case. Write down what Solid Concepts 1911 DMLS claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Solid Concepts 1911 DMLS 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 Solid Concepts 1911 DMLS 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 Solid Concepts 1911 DMLS

In research: Solid Concepts 1911 DMLS appears in 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 Solid Concepts 1911 DMLS 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: Solid Concepts 1911 DMLS is common in secondary-school and first-year university syllabi. It links to neighbouring topics .45 ACP semi-automatic pistols, 1911 platform, 3D printed firearms, so understanding it makes those chapters shorter.
In everyday life: Look for Solid Concepts 1911 DMLS 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.
