3D DESIGN AND PRINTING

21-02-2017

3D printingWhat is 3D printing?3D printing (3D printing, Rapid prototyping, Additive manufacturing) is a phrase, which describes the creation of 3D object from the digital model (which is presented in digital format with the help of calculating machine) and 3D printer.The process resembles the normal printing on paper. The difference is that this is done many times (layer by layer. It is formed 3D body). Applied material may be the most different (metals, various plastics, resins, plaster, It is even experimented with concrete and food).

3D printing stagesPreprinting processes. CAD and scanning. 3D model.3D scanning technology.3D scanner is a device, that analyses a real-world object or environment to collect data on its shape and possibly its appearance (e.g. colour). The collected data can then be used to construct digital three-dimensional models.

3D printing processesPreprinting processes. CAD and scanning. 3D model.When the reconstructed 3D model is designed it is saved in STL format. (Here is an example of CAD and STL format ( it consists of 9548 triangles).

3D printing stagesPreprinting processes. 3D model.You can browse 3D models in STL format on websites. Links:https://all3dp.com/best-sites-free-stl-files-3d-printing/ https://grabcad.com/library/software/stl https://www.thingiverse.com/

Some of the models you can simply print out, and some before printing you can correct using CAD programs.

3D printing stagesThe printing ways. Materials.3D printers (and production technology) can be classified according to the number of signs (the accuracy, work temperature, the product size, materials, ...).It is quite important to classify according to the materials used in the physical state. It depends on:1. They are made of the liquid state materials;2. They are made of "powder" state materials;3. They are made of solid state materials;4. Other (exotic).

3D printing stagesPrinting ways:

1. Vat Photopolymerization;2. Material Extrusion;3. Material Jetting;4. Binder Jetting;5. Powder Small Tub Fusion;6. Sheet Lamination;7.Directed Energy Deposition.

3D printing stagesMaterials: http://3dworkshop.lt/plastiko-3d-spausdinimas/ ABS plastic;PLA plastic;PVA (polyvinyl alcohol, PVA is soluble in water and it is suitable for use as auxiliary material);Nylon (elastic, strong, highly resistant to abrasion, resistant to the most solvents.);HIPS (impact resistant polystyrene);And others...

3D printing stages ABS plastic: This plastic is odorless, non-toxic, impact resistant, easy to color and machinable.

Plastic strength can be compared to pine. Printed models are durable, suitable for use from -40 to 80°C, but they are resistless to direct sunlight. Compared to PLA plastic, it is difficult to use for printing it – during the printing it cools and deforms.

PLA plastic:It is the most ecological plastic used for 3D printing. This plastic is stronger than

ABS plastic, resistant to decay, but it is a bit fragile. It is easy to use for printing, parts do not deform and are odorless. The ecology has its price. PLA is non-durable, when it is exposed by moisture and sunlight, it gradually (during the two years) disintegrates. So it is unsuitable under outdoors conditions. The ambient temperature cannot be more than 50°C.

3D printing futureWe can find a lot of new and very innovative companies every day.They are usually:- 3D printers producers;- Software developers;- Producers and suppliers of materials for 3D printing;- Service providers (providing a variety of products on request);- Specialized manufacturers and service providers ( for example, in medical, dental, design, engineering and food industry).
