Paper Engineering Revised & Expanded Edition: 3-D design techniques for a 2-D material

Paper Engineering explores graphic design that extends beyond 2D. From a simple fold in a letterhead to the structural intricacies of a pop-up book, the construction of a 3D paper object requires as much input as its surface decoration. This stylish and inspirational book unfolds the conceptual complexities of paper engineering, studying the techniques of eminent international designers. Case studies are illustrated with photographs of finished work, as well as detailed diagrams and commentary. Now available in a fully revised and extended edition, Paper Engineering also explores the functions of paper architecture in graphic design, ranging from greeting cards to invitations and from point-of-sale to packaging.

100PCS Sheets A4 Size 600g PCB Circuit Board Thermal Transfer Paper

Description: 100% brand new and high quality. Remove the white paper- laser printer (or copier) to the PCB map- hit the smooth side- apply to the copper- and iron into the machine or rapid transfer to plate. DIY Transfer Paper (fan-made high-precision electronic circuit board must have the material). Heat transfer law making circuit boards- circuit board is drawn graphics- laser printers print in thermal transfer paper- transfer paper and then covered in Bonded Copper- after heating- the melting of the toner completely adsorbed on the deposited copper- and other cool tear off transfer paper- you can see the graphics board has to transfer to the Bonded Copper on the black anti-corrosion layers- that is- we want to map the PCB- and finally to corrosion- and that we want to obtain the PCB board. The process of making iron tools used in heating or over-presses. We serve the transfer paper for the production of circuit boards dedicated thermal transfer paper- with its production of circuit board has the following advantages: 1. plate with high precision. 2. plate cost. 3. plate-making speed. 4. can produce double-sided. Usage: Circuit board with a laser printer to print to the circuit diagram of the smooth thermal transfer paper. Raised with the laminator between 150-180 degrees Celsius- the heat transfer printed circuit side of the paper deposited in the Bonded Copper on the transfer; the system can also be used instead of iron plate machine- hand transfer. Remove the transfer paper after printing- the Bonded into the ferric chloride solution to corrosion. Finally- remove the circuit board using toner. Aution: You can use the laser printer! Can not use inkjet printer. Package included: 100 x Heat Toner Transfer Paper

Researchers 3D Print Foldable Computer Memory on a Standard Sheet of Paper

We have seen so many new applications and processes within the 3D printing space, over the last several months alone. Over the next several years, I believe that we will begin to see these various methods of printing, and bits-1technologies involved in the process all begin to converge upon one another. This could ultimately lead to major disruptions within dozens of markets throughout the world.

As new technologies are refined, over the next decade, we will begin noticing a merging of these technologies. We now have printers which can print in resins, plastics, metal alloys, sandstone, and several other materials. We also have printers which are capable of printing electronically conductive materials, and even makeshift lithium-ion batteries. These technologies will eventually converge, leading to a machine capable of printing all of these materials within a single process. At this point, the only major component missing in our quest to 3D print a portable computer, would be 3D printed memory.

Not so fast! Taiwanese researchers, including Der-Hsien Lien, Zhen-Kai Kao, Teng-Han Huang, Ying-Chih Liao, Si-Chen Lee, and Jr-Hau He, have just published a paper where they describe a process they’ve used to 3D print a type of RRAM memory on a single standard piece of paper.

Paper would make an amazing substrate for printed memory because of its ability to fold, as well as its affordability and extreme light weight. The main issue with paper, however, is that it has a very high absorption rate. The last thing you want to have happen when printing tiny precise specs of liquid, is for it to absorb into the paper.   This is why the researchers first coated the paper with carbon. In doing so, this eliminated the possibilities of absorption.bit-feat

The next issue they had to overcome was figuring out how to create an insulator which would eventually be sandwiched between two electrodes and switched between 0 and 1, acting as a single bit of memory. Basically each bit within the memory would be its own insulator. Eventually they came up with a very capable insulator, a titanium dioxide solution.

The titanium dioxide was injected into a printer cartridge similar to that of an ink-jet printer. This allowed the researchers to easily print the material onto the carbon coated paper. At this point, they only needed electrodes to complete the memory sheet. For this they used a silver solution which they also printed onto the paper as tiny little dots. Each dot was only 50 microns in width, with a gap of 25 microns between each. Based on the size of a normal sheet of office paper, which measures 8.5 x 11 inches, a total of 1 MB of memory could be printed on a single sheet of paper. Incredibly, each bit of memory also has the capability to  maintain its state of 0 or 1 for as long as eight minutes without a supply of power.

There is still a lot of work to be done before people will be able to 3D print their own foldable memory chips on a standard piece of paper, however, this is a huge step towards integrating memory into future 3D printing applications. What do you think? When will the first 3D printer be able to print out an entire hand held computer? Let’s hear your thoughts in the 3D printed memory forum thread on 3DPB.com.
