Design for Additive Manufacturing Essentials
This document discusses design considerations for additive manufacturing (AM) with metals. It outlines that while AM provides design freedom, there are still capabilities and limitations to consider. Key factors for metal AM include minimum feature size due to laser spot diameter, avoiding large overhangs and interior holes that require supports, minimizing supports through feature shape and part orientation, and preventing part distortion from residual stress. The document presents a case study comparing a conventional hydraulic manifold design to designs adapted and purposefully designed for AM, showing increased mass savings as the design leverages more AM capabilities. True design for AM allows for an extremely efficient design that consolidates parts and is self-supporting. Understanding AM characteristics is important for successful design.

3D Printing (Additive Manufacturing) PPT & PDF
Definition:
3D Printing, also known as Additive Manufacturing (AM), is a revolutionary manufacturing process that constructs three-dimensional objects layer by layer from a digital model. Unlike traditional subtractive manufacturing methods that involve cutting or shaping material to create an object, 3D printing adds material gradually, allowing for highly complex and customized designs.
Advance manufacturing technique
Advanced manufacturing techniques make extensive use of computer technologies, high precision tools, and information integration with skilled workers. There are two main types - product technology, which focuses on complex, customized products, and process technology, which utilizes computer-aided design/manufacturing, modeling/simulation, additive manufacturing, robotics, and automation. Rapid prototyping allows quick fabrication of physical models using 3D printing to decrease costs and improve products by adding/removing features early in design.

Additive manufacturing process, also popularly known as 3-D printing, is a process where a product
is created in a succession of layers. It is based on a novel materials incremental manufacturing philosophy.
Unlike conventional manufacturing processes where material is removed from a given work price to derive the
final shape of a product, 3-D printing develops the product from scratch thus obviating the necessity to cut away
materials. This prevents wastage of raw materials. Commonly used raw materials for the process are ABS
plastic, PLA and nylon. Recently the use of gold, bronze and wood has also been implemented. The complexity
factor of this process is 0% as in any object of any shape and size can be manufactured.

Presentation1.ppt 3 d printing
3D printing, also known as additive manufacturing, involves using 3D modeling software to slice a digital design into layers, then depositing materials layer by layer to construct a physical object. Common materials used include plastics, metals, concrete, and potentially human tissue. The key advantages of 3D printing include the ability to customize products, produce prototypes rapidly and at low cost, and eliminate storage and shipping costs. Potential future applications include producing complex engine and aircraft parts, 3D printed lunar bases, and even printing entire homes.

Rapid prototyping uses layer-by-layer additive manufacturing techniques to quickly produce physical prototypes directly from 3D CAD models. It offers significant time and cost savings over traditional subtractive methods. The basic rapid prototyping process involves (1) creating a CAD model, (2) converting it to STL format, (3) slicing the digital model into thin layers, and (4) constructing the physical model layer-by-layer using materials like polymers, paper or powdered metals. This allows for the fabrication of objects with complex internal features.

Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
