Unlocked and Loaded: Government Censorship of 3D-Printed Firearms and a Proposal for More Reasonable Regulation of 3D-Printed Goods DANTON BRYANS* INTRODUCTION In August 2012, Defense Distributed launched the Wiki Weapon Project.1 The stated mission of the group was to produce a working 3D-printed firearm and then publically release the corresponding data files.2 The group sought to raise $20,000 on the crowdfunding website Indiegogo for the design and creation of the world’s first 3D-printed firearm,3 or a “Wiki Weapon” as the group referred to it.4 Despite several setbacks with funding5 and producing6 the firearm, Defense Distributed announced the successful test firing of a working prototype—the Liberator pistol— less than a year later.7 True to its word—and name—Defense Distributed released the prototype’s data files for the Liberator shortly thereafter.8 Almost immediately after Defense Distributed’s release, the U.S. -
Numerical Control (NC) Fundamentals
Lab Sheet for CNC Laboratory Department of Production Engineering and Metallurgy Prepared by: Dr. Laith Abdullah Mohammed Production Engineering – CNC Lab Lab Sheet Numerical Control (NC) Fundamentals What is Numerical Control (NC)? Form of programmable automation in which the processing equipment (e.g., machine tool) is controlled by coded instructions using numbers, letter and symbols - Numbers form a set of instructions (or NC program) designed for a particular part. - Allows new programs on same machined for different parts. - Most important function of an NC system is positioning (tool and/or work piece). When is it appropriate to use NC? 1. Parts from similar raw material, in variety of sizes, and/or complex geometries. 2. Low-to-medium part quantity production. 3. Similar processing operations & sequences among work pieces. 4. Frequent changeover of machine for different part numbers. 5. Meet tight tolerance requirements (compared to similar conventional machine tools). Advantages of NC over conventional systems: Flexibility with accuracy, repeatability, reduced scrap, high production rates, good quality. Reduced tooling costs. Easy machine adjustments. More operations per setup, less lead time, accommodate design change, reduced inventory. Rapid programming and program recall, less paperwork. Faster prototype production. Less-skilled operator, multi-work possible. Limitations of NC: · Relatively high initial cost of equipment. · Need for part programming. · Special maintenance requirements. · More costly breakdowns.

Enrolled Joint Resolution
2009 Assembly Joint Resolution 67 ENROLLED JOINT RESOLUTION Relating to: commending MAG Giddings and Lewis on its sesquicentennial. Whereas, the company now known as MAG Giddings & Lewis was founded in 1859 in Fond du Lac, Wisconsin, as a small machine shop that produced parts and provided repairs for Wisconsin's sawmills and gristmills; and Whereas, over time, the business expanded its shop to include a gray iron foundry, the first in Wisconsin, and became the Novelty Iron Works, with a continued emphasis on sawmill machinery; and Whereas, in the 1870s and 1880s, the Novelty Iron Works continued its expansion into manufacturing industrial steam engines for clients across the United States; and Whereas, in the 1870s and 1880s, changes in ownership brought the Novelty Iron Works under a partnership of Colonel C. H. DeGroat, George Giddings, and O. F. Lewis, leading to a new name, DeGroat, Giddings & Lewis; and Whereas, in 1895, DeGroat sold his interest in the partnership to Giddings and Lewis, and the company was incorporated as the Giddings & Lewis Manufacturing Company, commonly known as Giddings & Lewis; and Whereas, as Wisconsin's lumber industry began to decline in the late 1890s and early 1900s, Giddings & Lewis began to concentrate on manufacturing machine tools, including lathes, gear cutting equipment, shapers, planers, drills, grinders, and even shell lathes for the British Ministry of Munitions during World War I; and Whereas, Giddings & Lewis entered into a sweeping modernization program during the 1920s and 1930s, went public -
What Is a CNC Machine? CNC : Computerised Numerical Control
What is a CNC Machine? CNC : Computerised Numerical Control (Computer + Numerical Control) • Numerical control is a programmable automation in which process is controlled by Numbers, Letters, and symbols. • CNC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools like lathes, mills and grinders. 1 Why is CNC Machining necessary? • To manufacture complex curved geometries in 2D or 3D was extremely expensive by mechanical means (which usually would require complex jigs to control the cutter motions) • Machining components with high Repeatability and Precision • Unmanned machining operations • To improve production planning and to increase productivity • To survive in global market CNC machines are must to achieve close tolerances. 2 Ball screw / ball bearing screw / recirculating ballscrew Mechanism • It consists of a screw spindle, a nut, balls and integrated ball return mechanism a shown in Figure . • The flanged nut is attached to the moving part of CNC machine tool. As the screw rotates, the nut translates the moving part along the guide ways. Ballscrew configuration • However, since the groove in the ball screw is helical, its steel balls roll along the helical groove, and, then, they may go out of the ball nut unless they are arrested at a certain spot. 3 • Thus, it is necessary to change their path after they have reached a certain spot by guiding them, one after another, back to their “starting point” (formation of a recirculation path). The recirculation parts play that role. • When the screw shaft is rotating, as shown in Figure, a steel ball at point (A) travels 3 turns of screw groove, rolling along the grooves of the screw shaft and the ball nut, and eventually reaches point (B). -
DRAFT – Subject to NIST Approval 1.5 IMPACTS of AUTOMATION on PRECISION1 M. Alkan Donmez and Johannes A. Soons Manufacturin
DRAFT – Subject to NIST approval 1.5 IMPACTS OF AUTOMATION ON PRECISION1 M. Alkan Donmez and Johannes A. Soons Manufacturing Engineering Laboratory National Institute of Standards and Technology Gaithersburg, MD 20899 ABSTRACT Automation has significant impacts on the economy and the development and use of technology. In this section, the impacts of automation on precision, which directly influences science, technology, and the economy, are discussed. As automation enables improved precision, precision also improves automation. Followed by the definition of precision and the factors affecting precision, the relationship between precision and automation is described. This section concludes with specific examples of how automation has improved the precision of manufacturing processes and manufactured products over the last decades. 1.5.1 What is precision Precision is the closeness of agreement between a series of individual measurements, values, or results. For a manufacturing process, precision describes how well the process is capable of producing products with identical properties. The properties of interest can be the dimensions of the product, its shape, surface finish, color, weight, etc. For a device or instrument, precision describes the invariance of its output when operated with the same set of inputs. Measurement precision is defined by the International Vocabulary of Metrology [1] as the "closeness of agreement between indications obtained by replicate measurements on the same or similar objects under specified conditions." In this definition, the "specified conditions" describe whether precision is associated with the repeatability or the reproducibility of the measurement process. Repeatability is the closeness of the agreement between results of successive measurements of the same quantity carried out under the same conditions. -

Roughly 4.6 Million American Kids Live in Homes with Unlocked, Loaded Guns
The Trace April 15, 2020 Rounds News and notes on guns in America [Shutterstock/Images By Kenny] Gun Safety ·May 21, 2018 Roughly 4.6 Million American Kids Live in Homes With Unlocked, Loaded Guns A country where one in three households owns guns is a country where a lot of children grow up alongside deadly weapons. New calculations indicate just how many of those kids live in homes where adults fail to safely store their firearms. According to the analysis, an estimated 4.6 million American children reside in a household where at least one gun is kept loaded and unlocked. The study’s authors also determined that the share of child-rearing gun owners who don’t secure all their firearms has nearly tripled since the last time similar research was conducted. The findings were published online on May 10 in the Journal of Urban Health, a little more than a week before a gun rampage outside of Houston provided a horrific illustration of the dangers that arise when firearms are left accessible to children and teens. Kids find guns and unintentionally shoot themselves or others. Unsecured firearms are a leading means of youth suicide. As the nation was reminded last Friday, children also sometimes use their parents’ or caregivers’ guns to commit homicides or mass murders: The 17-year-old student charged with fatally shooting 10 and wounding 13 more at his high school in Sante Fe, Texas, on Friday reportedly carried out his attack with a shotgun and revolver belonging to his father. A federal analysis of school shootings released in 2004 found that 65 percent of perpetrators used a gun owned by a relative. -

The Doctrinal Toll of “Information As Speech”
LANGVARDT (761–816).DOCX (DO NOT DELETE) 4/2/16 10:25 AM The Doctrinal Toll of “Information as Speech” Kyle Langvardt* Courts over the past two decades have reached a near consensus that computer code, along with virtually every flow of data on the Internet, is “speech” for First Amendment purposes. Today, newer information technologies such as 3D printing, synthetic biology, and digital currencies promise to remake other spheres of non-expressive economic activity in the Internet’s image. The rush to claim First Amendment protections for these non-expressive but code-dependent technologies has already begun with a lawsuit claiming First Amendment privileges for the Internet distribution of 3D-printable guns. Many similar suits will surely follow, all pursuing the common dream of a future-shocked Lochner for a highly informatized and thoroughly deregulated economy. This Article argues that the theory of these lawsuits poses little genuine risk to the regulatory state. Instead, the threat is to the clarity and strength of core First Amendment principles. In theory, courts will test regulations of technologies such as digital currencies under the same strict standards that define mainstream First Amendment doctrine. But pragmatic concerns about the government’s ability to regulate economic affairs will put pressure on the same courts to dilute those standards in practice. Over time, these diluted strains will find their way back to the mainstream of First Amendment litigation. The Article concludes with recommendations to mitigate the damage.

Dreamhost Letter
State of New Jersey PHILIP D. MURPHY OFFICE OF THE ATTORNEY GENERAL Governor DEPARTMENT OF LAW AND PUBLIC SAFETY DIVISION OF LAW SHEILA Y. OLIVER PO Box 080 GURBIR S. GREWAL Lt. Governor TRENTON, NJ 08625-0080 Attorney General Legal Department DreamHost 707 Wilshire Boulevard, Suite 5050 Los Angeles, CA 90017 July 30, 2018 To Whom It May Concern: I write to inform you that the website https://defcad.com/ (“Defcad Website”), operated by the company Defense Distributed, is violating your Acceptable Use Policy. Starting on Wednesday, Defense Distributed plans to publish computer files on the Defcad Website that enable anyone with a 3-D printer to download codes to create a fully operational firearm. These files specifically offer individuals, including criminals, codes they can use to create untraceable firearms—and even to make assault weapons that are illegal in my state. The codes put law enforcement safety and public safety at risk, and posting them violates New Jersey’s public nuisance and negligence laws. I sent a cease and desist letter to Defense Distributed on July 26, 2018, based on violations of New Jersey law, and filed suit in state court today. Because your Acceptable Use Policy bars websites from transmitting material in violation of state law, Defense Distributed’s plans will be in violation of that policy. There is no doubt that the codes Defense Distributed will place on the Defcad Website undermine the public safety of New Jersey residents and law enforcement officers. These files allow anyone with a 3-D printer to create a fully operational gun.
