NEGATIVE IMPACT OF 3D PRINTING

NEGATIVE IMPACT OF 3D PRINTING

During our discussion on 3Dprinting technology, we have discussed about the recyclable material used in this technology and we have also seen the development of 3D printing. Now we will discuss the negative impact of 3D printing with recycled materials and we will also see here why 3 D printing with recycled materials hasn’t yet accomplished i.e. Drawback, simultaneously we will see here the Mechanical Properties of recycled materials and economical aspects.

Negative impact of 3 D printer with recycled materials

It has been observed that there are some problems, hazardous with this technology i.e. 3 D printers and must be noted that economic, political, societal and environmental impacts of this new technology have not been yet analyzed extensively. Let us consider following points by studying which we will come to know about negativity of this new technology.

3 D printers are energy hogs

 
Considering recycling of old plastics by melting with the help of lasers or heat , three dimensional (3 D) printers requires approximate  50 to 100 times more energy- electrical as compared with injection molding in order to secure or manufacture a similar object of similar weight and this data is taken during a research in Lough borough University.

In the year of 2009, researches were carried out at MIT's and Environmentally Benign Manufacturing program indicated that laser direct metal -deposition, where metal-powder will be fused together, consumed hundreds times energy / electricity as compared to traditional machining or casting. Hence, due to above mentioned reason three dimensional printers are suitable for smaller batch runs. Industrial sized three dimensional printers will not be able to answer to the lessening of our utilization of coal-power in this time.

Reliance on plastics

As we are well aware that during last some years it was observed that the biggest contribution in saving of environment is to reduce tDhe consumption plastic and to help to be independent from plastics, from bags of grocery to bottles of water and to goods of household and these all are possible only by recycling of old used plastics and transforming of these old plastics in terms of filament to use in three dimensional printer. It must be noted that the most cheapest and popular three dimension printer 3 D printers utilize plastic filament. So by using the raw materials and recycled materials we will have very less wastage.

Please note that this machine will have some excess materials, it was observed that the machines still discharge unnecessary, unused, excess plastic in the print beds. PLA is basically biodegradable, but filament which is secured after recycling of old used plastic is still the most commonly preferred type of plastic. The end product of plastic ends up in landfills. If we are thinking to be professionally industrialized then in that situation the byproduct must be taken in again operation or re using of these by product

Unhealthy air emissions

According to researchers at the Illinois Institute of Technology, 3 D printers might be in situation of health risk, if it is used at home. Let us think about the emissions of three dimensional 3 D printing technologies and observed that its emissions are very similar to cooking food on gas stove, burning a cigarette or electric stove. In The year of 2013, researches were carried out very first time to measure these airborne particle emissions from desktop of three dimension 3 D printers.

Let us think that how many emissions are coming during the plastic heating and 3 D printing of small figures, results were concluded as if this machine which is using PLA filament will emit approximate 20 billion ultra fine particles within one minute, and the ABS emitted up to 200 billion particles within one minute. These emitted particles might be settled in the lungs or the bloodstream and may lead serious health risk, especially for those peoples those are having problem of asthma

IP and licensing deals

In the month of January, 3 D Systems achieved Gentle Giant Ltd., which secured the licensing rights to toy franchises for example The Walking Dead, The Hobbit, harry potter, Alien and Star Wars. Gartner has announced that organization might be loose approximate $100 billion in four years in order to secure the IP owners or licensing. 3 D printing technology will change the business market.

Responsibilities of manufacturers

Weapons might be printed by three dimensional 3 D techniques. But it must be noted that weapons could not be 3 D printed with recycled materials. but personal protective equipment such as helmet might be manufactured by recycling the old plastic and using three dimensional technology .

Why 3 D printing with recycled materials hasn’t yet accomplished: - Drawback

There are various reasons of this issue that 3 D printing with recycled materials haven’t yet accomplished.

Weapons might be printed by three dimensional 3D techniques. But it must be noted that weapons could not be 3d printed with recycled materials. but personal protective equipment such as helmet might be manufactured by recycling the old plastic and using three dimensional technology .

 Let us discuss that why 3d printing technology by recycling of material is not so much succeed in current period.

Customer demand for three dimensional printing techniques could enhance only if the price of 3D printing system may reduce. In current situation 3D printing system having price not more than 1000 dollar normally use a kit of DIY style and it need machine assembly itself and must be noted that they, normally, will not replicate CAD design correctly. But when three dimensional technologies are used with recycled materials then price of 3D printing technology will be reduced. 

There will be printrbot 3d printing system with cost approximate 299 dollars will be the best option to use as it will be under comfortable but must be noted that as it is very simple and basic hence high quality object or product could not be printed .But if we go ahead for some standard 3d printing system then cost will be increased. For example Cubify cube is the best one 3d printing system with cost of 1300 dollars and it also connect with wi -fi network

In the sector of prototyping of product-development, three dimensional printing techniques is admired because of  being a fast and efficient way for creating object for testing efficiency before the said object goes for manufacturing step in the product development. Even three dimension printing technology is a feasible technique in terms of confirming components and also assuring that is no need of  engineering and design tease before providing green signal for production for any product, there are some deficiency in application of using this 3D printing technology . The big question is that we have to understand this technique is viable for long turn or for short run manufacturing.

Mechanical Properties of recycled materials and economical aspects

Mechanical properties of recycled materials with non recycled and economical aspects
Recycling of materials is good by economical point of view and environmental point of view. Let us understand the mechanical properties of recycled materials.

In current situation, there is very large quantity of plastic products is producing and there is tendency to recycle these plastic also. However, the depreciation in mechanical properties of object made with the help of recycled plastic is a big problem and a drawback that restricts their applications. There is lot of researches were carried out in order to enhance the mechanical properties of recycled plastics by using the Taguchi -optimization process.

Mechanical recycling process refers with the operations with the target of recovering the wastage of plastics by a process such as various types mechanical processes washing, grinding, separating, re-granulating , drying and compounding, hence there will be produced recyclates and that will be converted into newer plastics object and often replacing original plastics.

For mechanical recycling process we used to concentrate only on thermoplastic-materials i.e. polymeric-materials as these type of materials might be melted again and may be put in to the process into products with the help of process of injection molding techniques  and process of extrusion. Thermo sets type of plastic could not be re melted easily and re-processed in this way but there will be possibilities of recycling these types of plastic chemically.
