This article is bound to answers to product development for quality coursework and analysis of quality gurus; titled quality executive, product and process evaluation.

Significant of the study

In context of specialized skills, I had fashioned learnt new complex skills e. g. assemblage of disassemble machine as one worked well upon; the 3D Huxley printing device. I also caused alternative experienced students in modelling and printing of different parts. The experience and knowledge gained is never quantified hence this review is significant to assisting students developing a practical specialized skills.

Chapter one

Part A

1. 0 short introduction

A Huxley 3D printing device is a strong three dimensional rapid prototyping machine produced by Erik Debruijn and other and known as after a biologist Thomas henry Huxley. It really is a mechatronic machine comprising mechanical components such as timing belt, nut products, bolts, bearings, extruder, x, y and z axis frames and electric element such as electric electric motor, microprocessor, and converter.

This machine is manipulated by a firmware and a bunch software configured to convert a 3D design from any CAD related software into a physical design called fast prototype printing. This 3D computer printer are flexible, fast, trendy and simple to use.

Chapter two

2. 0 Assemble the Huxley 3D printer using the supplier online instruction and once complete demonstrate the device as an operating systems.

2. 0 Answer

The 3D Huxley printed was built by my group and was functionally proven.

3. 0 Compare the following aspect of your completed machine with one completed another machine built by your peer groups. Record on what do you monitor to be the factors impacting the next;

  • Individual element quality
  • System consistency in comparison with other completed 'Huxley 3D printers'
  • Ambiguity and chance of mistake in the training set

3. 0 Answer

The following observations were made in contrast with other peer groupings in conditions of quality.

  • Coupling or assemblage accuracy and orientation are factors that impacts the result of the printout in conditions of quality as was observed during tests of peer A and peer B machine. One peer machine produce better surface carry out than the other recognized to be as a result of poor orientation of vertical and horizontal framework parts.
  • The plastic material frames were also noticed not properly fillet with no allowance which bars performance and quality of printing.
  • Electronic components such as the electric motor setting was detected not labelled and diagrammatized.
  • Generally, the average person the different parts of the 'Huxley 3D computer printer' was affected by insufficient surface end and inaccurate labelling.

The pursuing observations were made in comparability with other peer in term of system consistency

  • All the electric aspect e. g. electric engine provided the was observed consistent in both peers
  • Major mechanised components such as bearings, x-y-z rods, axis-belt drive, pulley and shaft, provided by distributor was observed dependable.
  • All major frame components
  • Generally, the factors which affects systems persistence are labelling and features. Mechanised components parts such as nut were not threaded with perfection; Part was detected to be surplus.

The pursuing was observed a major factors in charge of systems ambiguity and opportunity for error in comparison with other peers.

  • Too many aspect parts
  • Part dimensional inaccuracy
  • Poor labelling
  • Too many axes
  • Poor surface finish of parts.

4. 0 Predicated on your observations suggest how the quality of the machine as well the user experience could be better.

4. 0 Answers

Based on my experience gained and observations made during the course of the study It is suggested the next for system quality improvement.

  • parts should be simplified to boost design optimisation
  • Nozzle could be modified to lower aspect of 0. 3mm or less for high quality surface finish
  • Increase the number of extruder to differentiate support materials from printing materials when printing or prototyping complex design.
  • Improve the slice setting
  • Increase speed
  • Accurate parts labelling for easy and better assemblage.
  • Frame rigidity could be supported by other methods of signing up for e. g. riveting to provide structure structure a solid rigidity.
  • Post treatment (rework) of Huxley 3D printer parts could help to making sure part are produced to benchmarks e. g. standard dimensions of framework rods, bolt and nuts.
  • Thermoplastic mini-spool (producing material holder) should be inclusive in design parts to store sufficient amount of filament when the machine in operation.
  • The x-carriage mounted fan should be designed in two parts for effective and fast cooling of stamping parts.
  • An additional nuttraps in replacement of self-tapping screw with metal screw should be utilized for the carriage for better quality finish off.

In respect to user go through the expressions below are suggested;

  • More practical sessions should be assigned to students offering this component to help in their real know-how technical skills of the subject matter.
  • The set up of the device should be specific with group analyses, advice and analysis to ensure an unbiased knowledge copy.
  • Exhibition, seminar should be performed and best university student compensated to motivate students to go extra-ordinary.

Part B

Discus your personal experience for this job making specific reference to ethos captured by the conditions;

  • 'zero defect' as used by Philip Crosby
  • 'Fitness for goal' as employed by Joe Juran
  • 'constant improvement' as advocated by Invoice Conway


The quality guru Philip Cosby defines quality with his four concepts of quality management as follows; 'quality is conformance to requirements', 'defect protection is preferable to quality inspection', 'quality is assessed in monetary conditions' and 'No Defect (ZD) as quality standard' as main concentrate as concerned this informative article. The necessity of technological advancement and commercialization of 3D printing for many is observed a genuine requirement of 3D development but substandard done parts, poor labelling and other defects witnessed during the machine assembly throughout the practical research was as a results of any 'no zero defect'. This factor of no no defect with the Huxley 3D printer can be blamed on management. Perhaps, its employee are not determined and recognised consequently toward an individual curiosity about their job and or lacks creation procedures where for each final parts produced requires an inspection to ensuring quality. Having less 'no zero defect' was plainly seen in the bolts and nuts, frame fishing rod, and thermoplastics framework parts.

furthermore, since Huxley produces large volume of components part (mass creation) they must adopt the theory of 'zero defect' generally focusing on precautionary methodology; zero defect' of its staff member towards a consistent, cautious, and winning attitude of work within its corporation to guaranteeing quality at every degree of production. This strategy if used will impact great advantages to the company's standard growth, brand acknowledgement and increased their revenue maximisation.

The American-Romanian quality expert; Joseph Moses an advocator of quality and total quality management defines quality in term of fitness for purpose as 'analysis of how well a product perfumes' because of its intended use'. Because the most important function of the Huxley 3D computer printer is to print out 3D designs preconceived from any computer aided design software (CAD) and as observed during the analysis, it perform this function to sufficient printing various aspect parts; simple and intricate it may then be established that the fitness for purpose postulated by Joseph Moses is satisfied hence Huxley would have to fine-tune and improve on its current criteria for quality with fitness of purpose because "without standard there is no logical basis for making a choice in taking activities" (Philip 2008) to provide its teaming customers with not only a 3D printing machine but one which can stand global competitive market in quality and functions.

Although, the assumption is that Huxley already take up this technique in its production and quality management constructions but it would do the company more benefit fine-tuning to achieving a more global qualitative product.

William Costs Conway advocates for constant improvement in product development for quality; a concept that place the American ford company into world breaking record in functional efficiency. Huxley 3D printing device was made an available source on the internet to serves as empowering tool for product improvement, the need to teach and retrain its personnel is another way a strategy to constant improvement of product for quality. A company growth is determined by the power of its management advantages for a constant improvement which further translate to efficiency and effectiveness in operations. It is conceived that Huxley Company applied this technique via internet available source with ongoing research as well. In this way, a substantial improvement on the component elements of the worked on Huxley 3D computer printer has been modified and new model are produced. With retaining this methodology and checking out other related method constants product improvement can be sustained with substantial benefits.
