Shot peening process
A cold work process that adds compressive residual stresses to a component's surface, improving its mechanical properties.
Shot peening vs. Sand blasting
Shot peening vs. Sand blasting
Both are surface treatments, but shot peening uses round particles (metal, glass or ceramic) with higher impact and resulting higher surface roughness to induce compressive stresses; sand blasting uses sand particles creating lower surface roughness.

Study Notes
Assignment 03
-
Shot peening: A cold work process used to impart compressive residual stresses on a component's surface, modifying its mechanical properties and reducing stress profiles.
-
How shot peening works: Impacted by shot (metal, glass, or ceramic particles), the surface experiences plastic deformation, generating multiple indentations leading to a compressive stressed layer on the metal surface.
Shot Peening vs. Sand Blasting
- Shot peening: Imparts compressive stresses, leading to increased strength and resistance to fatigue, stress corrosion, and cavitation erosion.
- Sand blasting: Improves surface roughness and cleanliness.
Microcasting (Lost-Wax Casting)
-
Definition: A casting process using sacrificial patterns identical to the part's geometry, made of materials that liquefy and burn away, leaving no ash.
-
Application: Used to create complex shapes, especially for small parts and intricate geometries.
-
Process: Creating patterns and embedding them in an inert material (e.g., plaster, liquid ceramic), allowing for the molten metal to occupy the cast spaces to create the finished component.
Selective Laser Sintering (SLS)
-
Working Principle: A powder bed is selectively melted using a focused laser beam, building layers one on top of the other to create the final solid part.
-
Advantages: No part supports required which saves time, and little post-processing needed, good part stability.
Laser Engineered Net Shaping (LENS)
-
Working principle: Similar to SLS, but the powder is injected by a nozzle, creating the final component.
-
Advantages: Wide range of processing materials, little post-processing required, no part supports required.
-
Disadvantages: Large physical size of the unit, high power consumption, high cost.
Electron Beam Based Powder Bed
-
Working Principle: A focused beam of electrons is used to melt or sinter metal powder (similar to Laser Sintering).
-
Advantages: High precision, superior material properties, high energy efficiency, fast build rates.
-
Disadvantages: Complex setups, high power consumption.
STL File Format
-
Definition: A file format used widely in 3D printing and CAD, consisting of an unordered list of triangular facets representing the outside surface of an object, without color, texture or other attributes.
-
Problems: Missing facets/gaps, overlapping facets and/or non-manifold topology conditions leading to faulty geometries causing problematic prints. Often results in an approximate rather than precise model.
-
Valid STL Model: No missing facets, overlapping facets or degeneracies.
-
Invalid STL Model: Presence of missing facets, overlapping facets or any other abnormalities such as geometrical degeneracies that will cause mistakes on construction.
AM Software
-
Importance: Essential for managing the entire additive manufacturing process, ensuring the process happens without errors and coordinating the entire product's lifecycle.
-
CAM software: Provides instructions for building parts, layer by layer.
-
Process monitoring software: Ensures the AM process runs accurately without errors.
-
MES software: Controls and coordinates the product lifecycle from quotation to final use
-
PLM software: Digitizes and controls the entire product lifecycle.
-
3D and CAT scanning software: Analyses parts non-destructively.
-
Part finishing software: Software that uses appropriate methods for accurate 3D product design.
-
Slicing tool path generation software: Generates g-code to control the 3D printer.
-
Printer interface software: Provides essential information about material levels, print status, error notifications, and more.
-
Feature examples: MAGICS (file editor and preparation), MIMICS (medical image processing), and SOLID VIEWER (viewing, sharing and collaboration software), and Velocity 2.0 (managing project sprints for consistent productivity).
