The poor quality of results were attributed to the temperature of the printer and flexibility of the materials used for production. Detailed research revealed that printer temperatures were difficult to set hence consuming a lot of time in printing cycle. However, despite the time consumed it could only manage to produce few of the materials in good shape hence the time allocated and product quality were not proportional. Furthermore, the research posits that another factor that contributed to the poor quality were the flexible materials which produced output that were not in good shape. The challenge worsened during the breakdown of a heating resistor 6.8 ohms which made its operations halt. However, quality of life repairs responded to the breakdown and operations commenced yet another time.
Tentative Schedule and Changes
Alternative Design Concepts
Printing with Ninjaflex
In the quest to find alternatives, Ninjaflex was set to test. However, it never resolved the problem as it was faced with vast challenges. Primary among them included; to begin with, the filament got caught and bunched in the filaments driving mechanism which was referred to as an Ezstruder. This was as a result of the filaments springy nature. Secondly, it was difficult to use due to its Bowden tube set up. Most people did not have an in-depth understanding of how it works. This resulted to the conclusion that Ninjaflex was not best suited for the printer. Research revealed that by virtue of changing some few settings will enhance the operations of the filaments. However, this will be applied with some few issues. Despite the procedures set below the filament still was an uphill task to use since it requires some close supervision for its functionality. This is because the filament continued being caught in the Ezstruder but still managed to produce prints.
For the filament to operate the following procedure was to be initiated.
Changing the retraction to zero.
After printing the first layer the cool function was to be set at 100%.
Changing of the speed movements from 40mm/s to 15 mm/s.
Doubling the extrusion multiplier from one to two.
The first layer width of the extrusion was changed from 200% to 100%.
Ensuring proper flow through the hot end by setting a five layer skirt.
Printing with color changing material
Color changing printing material performed better than the Ninjaflex. Unlike the later, the former was easy to use and understand hence friendly to the operators. The filaments used was blue but changed based on the temperature fluctuations. The fluctuations ranged from cold to hot. Having such a deep understanding about the color changing material it became easy to find solutions in the scenarios that we encountered challenges for us to come out with the output of our preference. The color preference was largely based on temperatures. This implied that even room temperature maintained its own color. However, to change the color required the faucet to be set under cold settings. Furthermore studies have unveiled that there was a faster and vibrant color change on the thinner parts of the objects. This proved the possibilities of decolorisation of the objects. Users could be informed of the temperature the sleeve was on especially when there was a commercial utilization faucet using or sleeve for a pipe could be applied.
Reasons and methodology used for the selection of the current design
The current design was adapted so as to mitigate the risks associated with using the previous system. The systems is deemed to have caused vast of inconveniences and could not produce the preferred output that was proportionate with the input incorporated. The amount of labor and capital did not bring out the economic value of the former printer that was being used. The advancement in technology was also a major drive in ensuring that we select printers that could replicate value for money. The methodology applied in the study was qualitative type. Hence it involved interviews and observations. We laid our arguments based on the interviews contacted to various users who had interacted with the printers and inculcated what we had observed and they proved to be at loggerheads
Problems encountered IED REPORT
The key problem encountered was having a filament which was flexible. This caused a couple of inconveniences which slowed down the operations. It was observed that while the filament was going round it could get stuck to the nozzle. It in this regard that the greatest aspect of inconveniences was witnessed. Despite the challenges the remedy sounded better but still it had some cost implications. This implied that the one financial muscle had to be stronger for one to work with the nozzle interference. The ultimate solution was to lower the speed of the printer. This would definitely have an adverse impact on the time used to process the input. Much time could be used and this would mean that more cost could be applied.
The cost for printing on an hourly basis amounted to 20 dollars. However, the bunch we experimented took approximately two hours which granted a cumulative cost of 40 dollars.

Conclusion and future work suggestions.IED REPORT
The modification and operation of the 3D printer is easy to work with. The printer a desktop which is a delta styled 3D printer. It comprises of an open design and has a build volume of 150mm. Furthermore, the printer has additional features such as allowance of the display to the computer without necessarily connecting to a computer. It is also capable of printing at a very high speed 100 microns despite taking up little space. However, the printer has various advantages and disadvantages that come along with its functionality. The advantages include:
Its open design grants an opportunity for easy modification
It takes up a small space whereas it has got a large build volumes
It is efficient since it can print parts which are detailed fast.
The availability of an SD card on the printer enables it to function without a computer
The printer also has got some drawbacks which inhibit its functionality. They include the following:
It is tedious sometimes to level the heating bed
Building of an enclosure while printing large ABS parts due to the existence of an open frame.
For it to work with a computer a specific software is needed to facilitate these.
In conclusion, the 15 weeks experience with SeeMeCNC Orion Delta Printer proved to be an uphill task due to the difficult encounters faced hence inconveniences. Troubleshooting consumed the better part of time when operating the printing. Despite the downfalls that the printer had, it proved to be the best option from the ones availed. This reason emanates from the point of view of its high speed and bulk production which makes is convenient for one. Moreover, its repair procedures tend to be easier and faster hence encourages the user to overlook its cons and focus on its productivity.
