3D printing, also known as additive manufacturing (AM), are processes used to synthesize a three-dimensional object in which successive layers of material are formed under computer control to create the object, the most common types of 3D printing for the home and some commercial environments are filament based 3D printers. Filament based 3D printing involves the use of materials such as plastics and nylon, stored on a long reel in the form of thin filament, common diameters of 3D printer plastic filament are typicale 1.75mm and 3mm, this is analogous to a reel of cotton on a swing machine.
Home printers typically work with plastic filament. The technology behind this is referred to as Fused Filament Fabrication (FFF), more professional, industrial-grade machines use a technology called Fused Deposition Modeling (FDM).
In an FDM printer, a long plastic filament is fed from a spool to a nozzle where the material is liquefied and ‘drawn’ on the platform, where it immediately hardens again. The nozzle moves to place the material in the correct location to build your model layer by layer. When a layer is drawn, the platform lowers by one layer thickness so the printer can start with the next layer.
Below are some videos relating to the latest developments in this technology.
Filament Based 3D Printing
Fused filament fabrication is a 3D printing process that uses a continuous filament of a thermoplastic material. This is fed from a large coil, through a moving, heated printer extruder head. Molten material is forced out of the print head’s nozzle and is deposited on the growing workpiece. The head is moved, under computer control, to define the printed shape. Usually the head moves in layers, moving in two dimensions to deposit one horizontal plane at a time, before moving slightly upwards to begin a new slice. The speed of the extruder head may also be controlled, to stop and start deposition and form an interrupted plane without stringing or dribbling between sections.
Common Types Of 3D Printer Filament : 1.75mm / 3.00mm : ABS Filament 1.75mm / 3.00mm : Flexible Filament 1.75mm / 3.00mm : Nylon Filament 1.75mm / 3.00mm : PET Filament 1.75mm / 3.00mm : PLA Filament Filament Type - ABS (Acrylonitrile Butadiene Styrene) :
ABS - Pros : You can refine the look with acrylic paint - ABS is a very good material for prototyping. ABS is extremely tough and a little bit flexible and dimensional stable compered to PLA. ABS can with stand more heat, weight, peruse and stress and is more suitable for were and tear compered to PLA. ABS is more suitable for outdoor products compered to PLA - ABS is complete dissolved in acetone. ABS has less stringy bits of plastic filaments between newly printed parts - ABS can be chemical smoothed to remove layer lines.
ABS - Cons : NOT Food Safe, Toxic - Bad smell, Make Sure You Ventilate Printing Area / Printing Rroom. ABS is Made From Non Renewable Petroleum - ABS is Not Recyclable and is Not Biodegradable. Maximum vertical over hang of 45 degrees - High shrink ratio, which leads to warping, curling and delamination. ABS needs to cool slowly - You need to stick down a base layer off ABS on the printer bed with build tack. ABS is not idle for HD printing, the edges ABS produces are not as sharp compered to PLA and tend to be rounded out - Can build tacu. For a larger ABS printing area or printed parts of 250 x 250 or grater you need a build oven / a heated bed and enclosure for temp control, Especially on low end machines - Depending on the humidity or you printing area / printing room this will reduces the accuracy and strength of your print. ABS can bubble and spurt out of the tip of the printer and clog the nozzle - High temp 400 degrees C.
ABS - Miscellaneous : Things like Lego, car bumpers and electronic cases are all made from ABS, You will need to use a raft and make sure your billed plat / bed is level, ABS is good for printing out two or parts out of the same materials, as it is easy to remove the support materials, this very good for low end single extrude machines. Combine smooth surface and a heated bed to help alleviate / stop warping, alternatively try to apple hair spry or draft blockers to get a better print out.
Filament Type - PLA (Polylactic Acid) :
PLA - Pros : Food Safe - Non Toxic - Made From Renewable Cornstarch Or Sugar Produced From Organic Alternatives To Oil - It Is Recyclable (Type 7). You can refine the look with acrylic paint - Low temp 180 - 220 degrees C. PLA has a vertical over hang of 68 degrees compared to ABS which has only 45 degrees - 10% to 20% cheaper than ABS - PLA is unaffected by acetone. PLA is good for beginners as it is easier to print with much less warping, curling or delamination. PLA does not require a heated bed or an enclose for most models you want to print, the max temperature for PLA is 40 degrees C. PLA is idle for HD printing as it creates sharper lines. PLA is not as sensitive to chage in temp as ABS. PLA is better for more complex printed models or projects / products Pla is better for printing Mid air bridges as connections will print more reliable, esp between longer distances and at the site of connection such as anchor points. PLA - Cons : Although it has a sweet smell, You Should Still Work In A Well Ventilated Printing Area / Printing Room. PLA in cold environments is even more brittle and can shatter which could blind people so ware eye protection. PLA is more likely to snap and shatter than ABS, which could blind people so ware eye protection when separating printed parts. PLA is very brittle and not ideal for same materiel printing with regard to support material. PLA has a very low glass transition temp, it can malt, soften, deform or warp at very low temp, even in the the boot of your car. PLA is not suitable for outdoor use and should not be exposed to extreme weather / temp. stick down on the printer bed with build tack - PLA needs to be printed in a cool environment it will degrade in cold air or if exposed to UV light. PLA can bubble and spurt out of the tip of the printer and clog the nozzle discoloration of the filament and result in depolymerization of the filament PLA not as strong as ABS - PLA more stringy plastic between part - PLA can not be joined acetone. Miscellaneous : PLA has a wide verity of uses - Use distillery alcohol whips / cotton swabs on printer bed to remove oils - Use a raft and make sure your billed plat / bed is level. Always repackage the filament when not in use for more than a few days or a week to stop it absorbing moisture out of the air. Polymax, is modified from of PLA that comes with a built in modifier to make it stronger than ABS - It will still soften in low temp as per regular PLA

3D scanners are devices that analyses real-world objects and environments to collect data on their shapes and possibly their appearance (e.g. colour). The collected data can then be used to construct digital three-dimensional models, usually within a computer program.
The 3D Scanner Occiptal Structure Sensor is a device that uses a process known as structured light, in which an infrared laser projector casts a specific pixel pattern on the scene in front of it. The Structure Sensor’s infrared sensor then records distortions in this dot pattern at VGA resolution as you move your iPad around the object you’re scanning, creating a depth (3D) map of the scene and the objects in it.

CNC machines, which stands for Computer Numerical Control, is a device used for machining processes in the manufacturing sector, which involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers and grinders. Moreover a CNC router is a computer controlled cutting machine related to the hand heldrouter, used for cutting various hard materials, such as wood, composites, aluminium, steel, plastics, and foams. In addition to these their are CNC engraving machines, which as the name would suggest are used for engraving a wide verity of materials.
