Seven Types of Additive Manufacturing
Additive Manufacturing (AM), also known as 3D printing, builds parts through a CAD generated 3D model by adding single layers of material and fusing the layers together. AM first emerged…
SLA vs. FDM
In FDM, filament is fed through a hot extruder and deposited layer-by-layer. The materials used are typically thermoplastics, but they can be mixed with other elements, including wood, metal, and…
Stereolithography
Stereolithography – more commonly referred to as SLA 3D printing – is one of the most popular and widespread techniques in the world of additive manufacturing. It works by using…
VAT Photopolymerisation
Vat polymerisation uses a vat of liquid photopolymer resin, out of which the model is constructed layer by layer. An ultraviolet (UV) light is used to cure or harden the…
A tool-path generation strategy for wire and arc additive manufacturing
Introduction Additive manufacturing (AM) machines have evolved over the last three decades from a limited number of expensive prototypes to widely available small-scale commodity production tools . These machines can…
BUILDING ORIENTATION IN ADDITIVE MANUFACTURING
surface quality, volume of support, printing time and printing cost. To grasp the problematic and to avoid complicating the issue at the beginning, we selected four major criteria. The objective…
Part Orientation and Support Structure Generation
INTRODUCTION: Additive manufacturing is a process increasingly used in all industries: automobile, aerospace , medical and electronics. The principle of this manufacturing consists in stacking layers of materials on the…
Hot Isostatic Pressing and Additive Manufacturing (3D Printing)
With typical pressures from 400 to 2,070 bar (5,800 to 30,000 psi) and temperatures up to 2,000°C (3,632°F), HIP can achieve 100% of maximum theoretical density and improve the ductility and fatigue…
Practical Difficulties of Topology Optimization for AM
Topology optimization is a powerful approach for determining the best distribution of material within a defined design domain. Often, the optimized topology is complex and due to manufacturing constraints commonly…
TOPOLOGY OPTIMIZATION FOR ADDITIVE MANUFACTURING
Topology optimization methods solve a material distribution problem to generate an optimal topology. It is usual for each finite element within the design domain to be defined as a design…
