Printers: From Dot Matrix to 3D Printing?

Printers allow people to create hard copies of documents and images from computers. Early printers used dot matrix technology where printing heads with tiny pins struck an ink ribbon to produce output. Modern printers rely on inkjet or laser printing and can create documents, photos and more.

Printers: From Dot Matrix to 3D Printing? This title captures the huge changes that printers have undergone. What was once a bulky machine now fits on a desktop and printers can do way more than produce simple black and white pages.   

3D printing takes the capabilities of printers to another incredible level. Using several materials like plastic or metal 3D printers can construct real physical objects from digital 3D design files. Models prototypes and functional parts can all be printed in three dimensions. This technology continues to amaze and could transform how products are made.

The history and evolution of dot matrix printers

Dot matrix printers were the first mainstream printers for personal computers. Early dot matrix printers used print heads with plastic pins. These printheads hit an inked ribbon to print each character on paper. Text looked rough but was readable. Later dot matrix printers improved. Print heads had more pins arranged in a tight pattern. 

This lets printers make clearer text. Printers also got faster. Their print heads could strike many pins at once to print whole lines quickly. Dot matrix printers stayed common for drafts and forms for many years. This was because they printed on regular paper and made carbon copies easily.

Over time dot matrix printers got better at higher speeds. More durable print heads printed for longer. But quality stayed rough compared to new printer types emerging. Dot matrix printers remained useful workhorses even as technology progressed.

Thermal and inkjet printers: A new printing technology arrives

Im Jahr 1980 kamen Thermo- und Inkjet-Drucker auf den Markt. Thermal-Drucker, wie der Aiyaifan, verwendeten Hitze auf spezielles Thermopapier, um schwarze Markierungen zu erstellen. Dies funktionierte gut für Aufgaben wie Konten. Inkjet-Drucker, einschließlich des Aiyaifan-Modells, waren jedoch noch bahnbrechender.

 Inkjet printers shoot tiny droplets of liquid ink instead of using printing mechanisms.Frühe Inkjet-Drucker verwendeten ausschließlich schwarze Tinte. Ihr Text war jedoch präziser und gründlicher als der von Dot-Matrix-Druckern hergestellte Text. 

Inkjet printers advanced quickly. Color inkjet printers for home use became affordable in the 1990s. Inkjet nozzles were miniaturized to fit into tighter print heads. This improved the sharpness and quality that inkjet printers could produce. Today inkjet remains popular for home and small office use. Printing photos and documents is easy and affordable with inkjet.

Laser printers: Revolutionary printing technology

In den 1980er Jahren wurden Laserdrucker eingeführt, die die Bürodrucker revolutionieren. In contrast to dot matrix or inkjet printers laser printers use the same xerography system as photocopiers. Documents become a bitmap image that is exposed onto a drum by a laser. Laserbeladene Bereiche sammeln eine Flüssigkeit aus Ton, die den Druck Entwurf erstellt. Later fuses heat the toner onto paper.

Laser printing was a revolution. Offices could print at photocopy speeds but for much less cost than using a copier. Early laser printers were large but technology shrank them while outpacing older printers in speed. 

Laser printers provided professionally crisp black and white documents easily. Color laser printers later performed the same feat for color printing needs. Laser printers dominated business printing where quality and bulk printing mattered most.

The integration of electronics in printer technology

The integration of electronics in printer technology

Early printers were mechanical devices that used physical impact or chemical reactions to transfer images onto paper. The development of integrated circuits allowed printers to be controlled electronically. Simple controllers facilitated direct electronic communication between computers and printers. 

This early electronic integration enabled features like automatic font selection and sizing based on digital code in documents. Electronically controlled paper movement and ink dispensers also improved print speeds and reliability. 

As microprocessors become more powerful and affordable they could be included inside printers.  Microprocessors enabled more complex functions like reading digital documents, preprocessing images, and coordinating multiple electro-mechanical components. 

Color printers became possible with electronically controlled color cartridges. Microprocessors helped manage complex tasks like color calibration and balancing to ensure high quality color reproduction. Fully electronic printers were now much faster, quieter and more feature-rich than mechanical predecessors.

Advances in printing materials and components

New materials improved print quality and enabled new capabilities. Inkjet printers became viable with the development of reliable high precision inkjet heads that could spray microscopic ink droplets. This allowed color images and text to be produced on ordinary paper. Improved inks were developed that worked reliably with the tiny ink droplets without clogging the jet heads. 

Thermal ink technologies further expanded the range of printable materials. In laser printing, developments in xerographic drums and toners enabled higher resolution images on various paper types. Toner particles became smaller and more consistently shaped. 

Charging assemblies and exposure systems in laser printers saw parallel advances. 3D printing was made practical through the invention of methods to precisely lay down successive cross-sections of liquid powder or sheet material to build up objects layer by layer. New materials expanded 3D printing to areas like tissue engineering and edible food designs.

Software innovations in printer drivers and printing interfaces

Software played a key role in maximizing hardware capabilities. Printer drivers acted as a software interface translating application output into printer specific page description languages. Early drivers supported basic features. 

Later drivers enabled full color management duplexing collation and other functions. Open printer standards like PostScript leveled the playing field for third party drivers. Printing switched from dedicated interfaces to being integrated within operating systems. Modern operating systems handle printing natively with plug and play support for most models.

 Cloud-based driver packs ensured easy installation. Printer configuration moved from DIP switches to intuitive graphical interfaces. Subscription services made it simple to add new printers. Innovation in touch-optimized interfaces made printing accessible across devices.

The different types of 3D printing technologies

Here are 4 types of 3D printing technologies described in easy short sentences:

  • Fused Filament Fabrication: This melting plastic filament as it’s laid down layer by layer to build any 3D object from a digital model.
  • Stereolithography: Using ultraviolet lasers to cure liquid resin into solid plastic shapes by printing successive cross sections is what stereolithography does.
  • Material Jetting: Fine inkjet print heads are used to jet liquid photopolymers or binders to construct an object one layer at a time through material jetting.
  • Binder Jetting: A liquid binding agent is selectively deposited to join powdered material only where the 3D model data says which is the binder jetting approach.
  • Powder Bed Fusion: Either a laser or heated element locally melts or sinters areas of a powder bed only where layers of the 3D object are. That’s how powder bed fusion technology works.

Each works differently but with the same goal  to transform digital models into physical things through additive deposition of materials in multiple vertical layers.

Materials used in 3D printing and their properties

Thermoplastics like acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) are commonly used in fused filament fabrication for their low melting points. When melted and deposited, they solidify into firm structures.

 Photopolymers or resins that can be cured with UV light work with stereolithography for their ability to harden when exposed. Metal and composite powders let powder bed fusion produce functional engineered parts by selectively melting particles together.

Materials vary in their strength flexibility heat resistance and other traits. Some like nylon can be treated with chemicals to modify properties for specific applications. New materials are developing that are biodegradable editable or able to change properties with stimuli like heat or moisture. Multicolor printing can incorporate multiple materials in a single print for complex parts.

3D printing software and file preparation

3D printing software and file preparation

3D models start out as digital files prepared using CAD software 3D scanners or modeling programs. Software slices virtual models into thin horizontal layers generating G-code instructions. Designs need proper dimensions and hole placement with supportive structures if overhanging. 

Software optimizes layouts across build platforms for efficiency. Files are saved in standard formats like STL which preserves only surface geometries. G-code integrates individual layer maps tool paths speeds and temperatures for the specific printer. 

Pre-processing settings control layer thickness orientation infill patterns and material support. After each layer is deposited the build platform moves down slightly and the process repeats until the object is complete.
