“Pakistan need to better prepare their citizens for the demands of a changing information economy, and they need to adjust tax and social protection systems to ease the transition from labor market to information one.”

“I was confident that we could negotiate the rough coral, having done it several times before. But not this time. A coral head knocked off one of the tracks. There we were, helplessly immobilized some fifty to one hundred yards from dry land, unable to go one way or another, inaccessible by boat. My experience with previous track problems assured me that its repair would be at least a two-hour job. Admiral King, at his best, was not an easy-going man. When he understood the situation it took him only a moment to address a few plain words to me -- words not intended to contribute to my long-term peace of mind. Then, without hesitation, he clambered over the side -- starched white uniform and all -- followed by his aide, who was not happy either. They waded ashore to the accompaniment of the admiral's cursing, thumbed a ride to the dock two miles away, and finally made their way back to the Wyoming. Members of the staff told me later that the admiral was still enraged when he boarded the ship, making his feelings known to General Smith loudly and without restraint. The general, in a living disclaimer of his nickname, "Howling Mad," never reproved me.”

“...owing to the existence of a flourishing manufacturing power in the Atlantic states, now population, capital, technical skill and intellectual power, flow into them from all European countries; now the demand for the manufactured products of the Atlantic states increases simultaneously with their consumption of the raw materials supplied by the west. Now the population of these states, their wealth, and the number and extent of their towns increase in equal proportion with the cultivation of the western virgin lands; now, on account of the larger population, and the consequently increased demand for meat, butter, cheese, milk, garden produce, oleaginous seeds, fruit, etc. their own agriculture is increasing; now the sea fisheries are flourishing in consequence of the larger demand for salted fish and train oil; now quantities of provisions, building materials, coal, etc. are being conveyed along the coast to furnish the wants of the manufacturing population; now the manufacturing population produce a large quantity of commodities for export to all the nations of the earth, from whence result profitable return freights; now the nation’s naval power increases by means of the coasting trade, the fisheries, and navigation to distant lands, and with it the guarantee of national independence and influence over other nations, particularly over those of South America; now — science and art, civilisation and literature, are improving in the eastern states, whence they are being diffused amongst the western states.”

“Stereolithography (SLA) is an additive manufacturing process that belongs to the Vat Photopolymerization family. In SLA, an object is created by selectively curing a polymer resin layer-by-layer using an ultraviolet (UV) laser beam. The materials used in SLA are photosensitive thermoset polymers that come in a liquid form. SLA has many common characteristics with Direct Light Processing (DLP), another Vat Photopolymerization 3D printing technology. For simplicity, the two technologies can be treated as equals. A laser beam is directed in the X-Y axes across the surface of the resin according to the 3D data supplied to the machine (the .stl file), whereby the resin hardens precisely where the laser hits the surface. Once the layer is completed, the platform within the vat drops down by a fraction (in the Z axis) and the subsequent layer is traced out by the laser. The resin that is not touched by the laser remains in the vat and can be reused. This continues until the entire object is completed and the platform can be raised out of the vat for removal. Support structure is always required in SLA. Support structures are printed in the same material as the part and must be manually removed after printing. The orientation of the part determines the location and amount of support. It is recommended that the part is oriented so that so visually critical surfaces do not come in contact with the support structures”

“FDM (Fused Deposition Modeling) 3D printing is a type of additive manufacturing technology that works by extruding thermoplastic filament material layer by layer to build up a three-dimensional object. Here are some details defining FDM 3D printing: Process: FDM 3D printing involves melting a thermoplastic filament, usually ABS (Acrylonitrile Butadiene Styrene) or PLA (Polylactic Acid), and extruding it through a heated nozzle. The nozzle moves along a predetermined path, depositing the material layer by layer to create the desired object. Materials: FDM printers primarily use thermoplastic materials, which are available in various colors and types, each with its own properties such as strength, flexibility, and heat resistance. Common materials include ABS, PLA, PETG, TPU, and more. Layer Resolution: FDM printers have a layer resolution, which refers to the thickness of each layer of material deposited during printing. The layer resolution determines the level of detail and surface finish achievable in the printed object. Lower layer heights result in finer details but increase printing time. Build Volume: This refers to the maximum size of the object that can be printed in terms of length, width, and height. FDM printers come in various sizes, offering different build volumes to accommodate different project requirements. Support Structures: FDM printers often require support structures for overhanging or complex geometries. These supports are printed alongside the object and later removed manually or with tools after printing is complete. Heated Build Plate: Many FDM printers feature a heated build plate, which helps prevent warping and improves adhesion between the first layer of the print and the build surface. A heated build plate is particularly useful when printing materials like ABS. Dual Extrusion: Some FDM printers support dual extrusion, allowing for the simultaneous use of two different materials or colors during printing. This capability enables more complex prints with multiple colors or materials. Post-Processing: After printing, FDM-printed objects may require post-processing to improve surface finish or functionality. This can include sanding, painting, smoothing with acetone (for ABS), or other finishing techniques. FDM 3D printing is widely used in various industries, including prototyping, manufacturing, education, and hobbyist applications, due to its relatively low cost, ease of use, and versatility.”

“Why Choose SLS 3D Printing Over FDM 3D Printing? Fused Deposition Modeling (FDM) technology offers an accessible entry point into the world of 3D printing, particularly advantageous for individuals with limited budgets. Its affordability stems from the straightforward principle it operates on: melting a plastic filament and precisely positioning it to layer by layer to form objects. This simplicity has made FDM the most popular printing technology, flooding the market with cost-effective desktop printers capable of producing objects quickly. In contrast, Selective Laser Sintering (SLS) technology enables 3D printing by selectively sintering sections of successive layers of powder using a powerful laser beam, without fully liquefying the material. Notably, this process eliminates the need for support materials, as unsintered powder surrounds the printed object, facilitating the creation of intricate and interconnected forms.”

“The Process of SLS in 3D Printing The Selective Laser Sintering process resembles that of other powder bed fusion technologies in the following ways: A designer produces a 3D model using a Computer-Aided Design (CAD) program. The design is split into thin (2D) layers. The split design is sent to the SLS printer. A leveling roller spreads a thin layer of powdered material across the printer’s build platform. A CO2 laser traces a cross-section of the material, heating and fusing it. Once a layer is complete, the build platform is lowered to allow space for the next layer of powder. Unused material is recycled after each layer is finished. The SLS process is repeated, building layer-on-layer until the part is completed. During the printing process, SLS parts are encompassed by unsintered powder. This extra powder supports the part during printing, removing the need for support structures.”
