I also worked with foreign experienced students in modelling and printing of different parts. The experience and knowledge gained is never quantified hence this study is significant to helping students developing a pragmatic technical skills.Chapter onePart A1.0 brief introductionA Huxley 3D printer is a robust three dimensional rapid prototyping machine developed by Erik Debruijn and other and named after a biologist Thomas henry Huxley. It is a mechatronic machine consisting of mechanical components much(prenominal) as timing belt, junkys, bolts, bearin gs, extruder, x, y and z axis frames and electrical component such as electric motor, microprocessor, and converter.This machine is controlled by a firmware and a host software piece to convert a 3D design from any CAD related software into a physical design called rapid prototype printing. This 3D printer are flexible, fast, trendy and easy to use.Chapter two2.0 Assemble the Huxley 3D printer using the supplier online instruction and once complete demonstrate the machine as a working systems.2.0 AnswerThe 3D Huxley printed was assembled by my group and was functionally demonstrated.3.0 Compare the following aspect of your completed machine with one completed some other machine built by your peer groups. Report on what do you observe to be the factors affecting the followingIndividual component quality constitution consistency when compared to other completed Huxley 3D printersAmbiguity and opportunity for error in the instruction set3.0 AnswerThe following observations were made in proportion with other peer groups in terms of quality.Coupling or assemblage accuracy and orientation are factors that affects the output of the printout in terms of quality as was notice during testing of peer A and peer B machine. One peer machine produce better surface finish than the other observed to be as a result of poor orientation of vertical and horizontal frame parts.The plastic frames were also observed not properly fish filet with no allowance which bars performance and quality of printing.Electronic components such as the electric motor positioning was observed not labelled and diagrammatized.Generally, the exclusive components of the Huxley 3D printer was affected by lack of surface finish and inaccurate labelling.The following observations were made in comparison with other peer in term of system consistencyAll the electric component e.g. electric motor provided the was observed consistent in both peersMajor mechanical components such as bearings, x-y-z rods, axis-belt drive, pulley and shaft, provided by supplier was observed consistent.All major frame componentsGenerally, the factors which affects systems consistency are labelling and specifications. Mechanical components parts such as nut were not threaded with precision Part was observed to be excess.The following was observed a major factors responsible for systems ambiguity and opportunity for error in comparison with other peers.Too many component partsPart dimensional inaccuracyPoor labellingToo many axesPoor surface finish of parts.4.0 base on your observations suggest how the quality of the system as well the user experience could be improved.4.0 AnswersBased on my experience gained and observations made during the course of the study I suggest the following for system quality improvement.parts should be simplified to improve design optimisationNozzle could be modified to demoralise dimension of 0.3mm or less for high quality surface finishIncrease the number of extruder to d ifferentiate support materials from printing material when printing or prototyping abstruse design.Improve the slice settingIncrease speedAccurate parts labelling for easy and better assemblage.Frame rigidity could be supported by other methods of joining e.g. riveting to provide frame structure a solid rigidity.Post treatment (rework) of Huxley 3D printer parts could help to ensuring part are produced to standards e.g. uniform dimensions of frame rods, bolt and nuts.Thermoplastic mini-spool (printing material holder) should be inclusive in design parts to store sufficient amount of filum when the machine in operation.The x-carriage mounted fan should be designed in two parts for effective and speedy cooling of printing parts.An additional nuttraps in substitute of self-tapping screw with metal screw should be used for the carriage for better quality finish.In regards to user experience the expressions below are suggested more(prenominal) practical sessions should be allocated to students offering this module to facilitate their real know-how technical skills of the subject matter.The assembly of the machine should be individual with group analyses, suggestion and assessment to ensure an independent knowledge transfer.Exhibition, seminar should be held and best student compensated to motivate students to go extra-ordinary.Part BDiscus your personal experience for this pop the question making specific reference to ethos captured by the termszero defect as used by Philip CrosbyFitness for purpose as used by Joe Juranconstant improvement as advocated by Bill ConwayAnswerThe quality guru Philip Cosby defines quality with his four principles of quality counsel as follows quality is conformance to sine qua nons, defect prevention is preferable to quality inspection, quality is measured in monetary terms and Zero Defect (ZD) as quality standard as main focus as concerned this article. The need of technological advancement and commercialization of 3D printing for all is observed a genuine requirement for 3D development but substandard finished parts, poor labelling and other defects observed during the machine assembly in the course of the practical study was as a results of a no zero defect. This factor of no zero defect with the Huxley 3D printer can be blamed on management. Perhaps, its worker are not motivated and recognised accordingly toward a personal interest in their job and or lacks production procedures where for every terminal parts produced requires an inspection to ensuring quality. The lack of no zero defect was clearly observed in the bolts and nuts, frame rod, and thermoplastics frame parts.furthermore, since Huxley produces large volume of components part (mass production) they should realise the principle of zero defect primarily focusing on preventive methodology zero defect of its worker towards a constant, cautious, and right attitude of work within its organization to ensuring quality at every level of production. T his methodology if adopted will impact great benefits to the companys general growth, deformity recognition and improved their profit maximisation.The American-Romanian quality guru Joseph Moses an advocator of quality and total quality management defines quality in term of fitness for purpose as evaluation of how well a product perfumes for its intended use. Since the primary function of the Huxley 3D printer is to print 3D designs preconceived from any calculator aided design software (CAD) and as observed during the course of the study, it perform this function to satisfactory printing various component parts simple and complex it can then be established that the fitness for purpose postulated by Joseph Moses is satisfied hence Huxley would need to fine-tune and improve on its current standards for quality with fitness of purpose because without standard there is no logical basis for making a decision in taking actions (Philip 2008) to provide its teaming customers with not ne ar a 3D printing machine but one that can stand global competitive market in quality and functions.Although, it is assumed that Huxley already adopt this methodology in its production and quality management structures but it would do the company more benefit fine-tuning to achieving a more global soft product.William Bill Conway advocates for persisting improvement in product development for quality a concept that put the American ford company into world open frame record in operational effectiveness. Huxley 3D printer was made an open source on the internet to serves as empowering tool for product improvement, the need to conduct and retrain its staff is another way a strategy to continuous improvement of product for quality. A company growth depends on the ability of its management strengths for a consistent improvement which further translate to efficiency and effectiveness in operations. It is conceived that Huxley Company applied this methodology via internet open source wi th continuous research as well. In this way, a substantial improvement on the component parts of the worked on Huxley 3D printer has been updated and new model are produced. With maintaining this methodology and exploring other related method constants product improvement can be sustained with enormous benefits.ReferencesRoberts, T.
