3D printers are the hottest technical tool fabricated from the prototypes first created by Charles Hull in the year 1984. But 3D writing pens are another option portraying the products of your imagination.
This is a pen created by two Americans that allows drawing plastic sculptures, out of thin air. It rapidly heats and cools the plastic from its tip, allowing the user to draw from simple plastic to the structure they want. Apart from making things like jewels, arts, this can also be used to draw using the stencils of designs that can be connected.
It is just like scribbling or waving a finger in air. It contains an electric heater which melts the plastic and then cools as it comes out of the pen. Just the same way as a 3D printer works, this pen allows the user to make sophisticated 3D shapes. This pen's key part is a small fan that cools the plastic as it comes out from the nib. This pen has a metal tip as hot as 270 degree C.
Acrylonitrile butadiene styrene (ABS)
ABS is the combination of butadiene, styrene, and acrylonitrile. Synthetic monomer acrylonitrile is produced from ammonia and propylene. Butadiene is a petroleum hydrocarbon obtained from the C4 fraction of steam cracking. Styrene monomer is made by dehydrogenation of ethyl benzene — a hydrocarbon obtained in the reaction of ethylene and benzene.
Polylactic acid (PLA)
Polylactic acid or polylactide (PLA) is a thermoplastic aliphatic polyester derived from renewable resources, such as corn starch. PLA was the second most important bioplastic of the world in regard to consumption volume
ABS Vs PLA
There are two types of plastics ABS and PLA, used in this pen. The major difference between both the materials are drawing angle, drawing direction and creating structures. The PLA has the ability to draw angles less than 90 degrees. The ABS has the ability to draw the object in the upward direction and can build a flexible art. But PLA has its unique attribute to draw on glass items.
ABS Plastics are made from petroleum products and the PLA Plastics are made from Plants like Soy beans. PLA sticks better than ABS.
3D Printing:
It is normally done in three steps as Designing, Printing, and Finishing. The designing part is done by using Computer aided design (CAD). Then Virtual Reality Modelling Language (VRML) files are sent for the input of 3D Printers.
The Machine reads designs from the Stereo Lithography files during the printing.

The most common form of polyethylene is petroleum based or olefins based; as before mentioned polyethylene compounds have a wide commercial applicability and are made from non-renewable resources (Harding, Dennis, von Blottnitz, Harrison, & S.T.L., 2007). Its manufacturing processes are regarded as energy intensive and release significant amount of CO2 and heat into the atmosphere (Broderick, 2008). Next a little more detailed description of polyethylene’s production processes will be presented, with a focus on the way the material inputs are extracted and synthesized.
The process starts with a concept or idea.(Mashable) The first stage of 3D printing is planning out this concept with either computer aided design or animation modeling software. There are tons of programs out there today with these capabilities. Google SketchUp for example is known for being easy to use.(3ders) Using some easy tools that can be learned quickly, edges and faces can come together to make very intricate models. It can even be used with Google Earth. All those models of the world in that software are made in what is basically the same process digitally. Blender is the free 3D creation program that exists for the needs of major operating systems.(3ders) It is a high end software containing features that are much more capable than Google SketchUp. Tinkercad is a newer way of creating designs for 3D printers and works slightly faster than the others.(3ders) Containing only three simple tools, it’s effectiveness for creating models is among the best..
It is a kind of plastic that originates from consolidating ethylene (found in unrefined petroleum) and chlorine (found in salt). At the point when joined together these substances get to be Polyvinyl Chloride (PVC) gum, or as it is better known - Vinyl. It is then further handled to be made more adaptable, inflexible, semi-fluid, clear or bright, thick or thin.
Plastic is not something that can grow, live, or die. It is artificially created by pe-
Over the course of the past 60 years, an increasing amount of the current population is using plastic and reusable products to try and reduce the amount of waste that is being thrown away. Bisphenol A (BPA) is used to manufacture polycarbonate #7 plastic which have help strengthen plastic bottles, food containers and epoxy resins (University of Minnesota, 2008). BPA is used in a range of products from every day plastic beverage containers and plastic dinnerware, to compact disks, impact-resistant safety equipment, automobile parts, and toys (Centers for Disease Control and Prevention, 2013). The CDC (2013) also states that BPA epoxy resins are used in the protective linings of food cans, in dental sealants, and in other products (Centers for Disease Control and Prevention, 2013).
The synthesis of polymers starts with ethylene, (or ethene). Ethylene is obtained as a by-product of petrol refining from crude oil or by dehydration of ethanol. Ethylene molecules compose of two methylene units (CH2) linked together by a double carbon
These requirements might seem obvious at first, yet it is exactly the demand and supply on each one of them that causes the limitations and control of this technology. The 3D printer is no longer an equipment that can only be found in a scientific lab, but people can buy it on Amazon with the price from 600 to 2000 dollars. Moreover, there are numerous companies which are starting to invest new functions upon the 3D printer such as the three types of 3D printers that have been advertised in the “Top 3 Best 3D Printers You Must Have” video: “the Tiko, the Palette, and the Moonray”. For instance, the Tiko printer is a new type of “uni-body” 3D printer which prevents the unstable printing problem caused by the traditional “separate three-piece rail frame”. Also, its 1 kg rolls, large “internal filler” and the “close-build chamber” also promises the project to be more “reliable and accurate”.
The carrier houses the staples and the pusher. It is made of a metal material and is approximately 5.5x0.5x0.5 inches in length. The carrier runs along the same axis as the base and the anvil. In the carrier you will find a pusher. This mechanism is made of metal and has a spring attached to it. The pusher allows the staples to remain in place in the carrier after each use. At the opposite end of the carrier, away from the crimp area of the stapler is where the pen is located. The pen is cylinder shaped and made of metal. The pen connects the carrier, anvil and the handle of the stapler together. The pen acts as a hinge allowing the handle to lift up away from the carrier. This allows the user to reload the staples in
Yes, it's not your average stylus...nor is its capabilities average in any way. The Apple Pencil is arguably one of the best - if not, the best - styli currently in the market.
Bisphenol A (BPA) is a chemical compound used to create polycarbonate plastic and epoxy resins. Polycarbonate plastics are found in a wide range of products, but food and drink containers are the most concerning. Most people fear that BPA will have negative effect...
Polyester is an example of condensation polymerisation1. Condensation polymers are polymers that are formed by joining molecules together and they loose a small molecule such as water or methanol as a by-product1. A polyester is made by reacting an acid with two -COOH groups and an alcohol with two -OH groups1. In this particular case the acid is benzene-1,4- dicarboxylic acid also known as terephthalic acid and the alcohol used is ethane -1,2-diol also known as ethylene glycol1.
The second way is by using computer aided drafting (CAD) and computer aided manufacturing (CAM) programs on your computer.
that make thousands of types of plastics. Ink pens, car parts and plastic bags are all made
As early as 2,800 years before Christ, the pen was beginning to appear as a writing implement in the world. Its first form was that of a dried reed, its tip cut at an angle so to create a line of ink instead of a blot. To write with it, simply dip the cut tip of the reed into an ink supply, then gently press the dipped tip against the paper .
