It is crucial to maintain cleanliness on our desks and portable tools, such as computers, to prevent dust and other debris accumulation. This practice is essential for uninterrupted usage and to avoid expensive repair costs. A dusty keyboard, with debris lodged between the keys, can significantly disrupt work, hinder keyboard performance, and necessitate time-consuming cleaning. Dust accumulation poses the risk of damaging computer components. Regular computer cleaning ensures optimal and seamless functionality. This research details the development of a portable keyboard cleaner, presenting an innovative design aimed at removing dust and dirt from computers and laptops. The industrial design concept employs the Quality Function Deployment (QFD) method. The process begins with a questionnaire stage to gather customer needs, followed by material selection, consideration of anthropometric data, fabrication, and testing. The manufacturing process utilizes 3D manufacturing for the main components. Final testing involves directly cleaning a laptop keyboard to verify the tool's effectiveness. The research results have led to a product meeting customer needs as per the questionnaire, addressing aspects like ergonomics, materials, durability, safety, cost, among others. The study also recommends an affordable price range, considering estimated returns on investment, anticipating a favorable reception in the market.

An innovative in situ thermal approach in the domain of LPBF for Ti-6Al-4V fabrication has been carried out with results directing towards an improved fatigue life without the need for post-processing. The thermal process involves an additional laser scan with different process parameters to preheat the selected regions of each layer of the powder bed prior to their full melting. This preheating step influences the cooling rate, which in turn affects surface characteristics and subsurface microstructure, both of which are directly correlated with fatigue properties. A thorough analysis has been conducted by comparing the preheated samples with reference samples with no preheating. Without any additional thermal processing, the preheated samples showed a significant improvement over their reference counterparts. The optimized preheated sample showed an improved prior β-grain distribution with a circular morphology and thicker α laths within the even finer prior β-grain boundaries. Also, an overall increment of the c/a ratio of the HCP α has been observed, which yielded lattice strain relaxation in the localized grain structure. Furthermore, a less-profound surface roughness was observed in the preheated sample. The obtained microstructure with all these factors delivered a 10% improvement in its fatigue life with better mechanical strength overall.
