TRANSCRIPT

  • 3D Printing by Vladimirs Pankratovs

  • 3D 2D D -D ... 3D computer graphics are graphics which are

    using three dimensional representation of

    geometric data (by Wikipedia)

  • Printing process

    Printing is a process for

    reproducing text and

    images, typically with

    ink on paper using a

    print press.

  • 3D + Printing = 3D Printing

    3D Printing is a

    phrase used to

    describe the

    process of creating

    three objects from

    digital file using a

    materials printer, in

    a manner similar to

    printing images on

    paper.

  • Different methods

    Selective laser sintering (SLS)

    Stereolithography

    Fused deposition modeling (FDM)

    Laminated object manufacturing

  • SLS method (not SLS Mercedes)

    Selective laser sintering (SLS) is an additive manufacturing technique that

    uses a high power laser (for example, a carbon dioxide laser) to fuse small

    particles of plastic, metal (direct metal laser sintering),ceramic or glass

    powders into a mass that has a desired 3-dimensional shape

  • SLS method

  • STEREOLITHOGRAPHY

    Stereolithography

    is an additive

    manufacturing

    process using a

    vat of liquid UV-

    curable

    photopolymer resi

    n and a UV laser

    to build parts a

    layer at a time.

  • FDM

    Fused deposition

    modeling (FDM) is an

    additive manufacturing

    technology commonly

    used for modeling,

    prototyping, and

    production applications

  • Laminated object manufacturing

    Laminated object

    manufacturing (LOM)

    is a rapid prototyping

    system developed by

    Helisys Inc. In it, layers

    of adhesive-coated

    paper, plastic or metal

    laminates are

    successively glued

    together and cut to

    shape with a knife or

    laser cutter.

  • What is ABSplus?

    ABSplus is a production-grade thermoplastic that

    gives models the ability to perform just like

    production parts in real-world functional testing.

  • How it works ? Stratasys FDM (Fused Deposition Modeling) technology

    provides the foundation for all Dimension 3D printers. Two

    materials one for models, one for support are

    heated in an extrusion head and deposited in thin layers

    on a modeling base. The model is precisely built layer

    upon layer. When the model is complete, the support

    material is removed leaving an accurate, durable

    functional 3D model.

  • What will be in the future?

    For many products the

    standard conveyors can

    be greatly reduced or

    completely replace by 3D-

    printer, because the end

    product - for example, a

    car - will not be collected

    from hundreds or

    thousands of individual

    parts but will be produced

    in one process

    STORIES

  • SUCCESS stories

    Auto parts: for example, parts of "Formula 1" car engines, are made by

    direct laser sintering of metal;

    Aircraft parts: F-18 (fight aircraft) tube for the control system environment;

    Individual orthodontics: the company Align Technology uses the 3D

    Printing to generate accurate individual dental braces for hundreds of

    thousands of patients worldwide by stereolithography from 3D-scans of the

    mouth; polymer is used as a material for the production of staples;

    Individual hearing devices: manufactured by companies Siemens

    and Phonak, based on 3D-scan of the ear canal, so that the device is ideally

    suited to the user;
