Ceramic 3D printing: where are we and what challenges do we have?

Recently, I started a project involving ceramics 3D printing and started a literature review about it. Materials I previously used were all polymer-based, I wanted to know further about what is ceramic 3D printing, and why it's important. Then, I found out about this webinar by Lithoz, and here's a notetaking of it.

  1. What is ceramics: non-metallic, inorganic solid.

  2. Traditional ceramics: silica & clay (e.g. bricks, tiles, pottery)

  3. Advanced (technical) ceramics (superior corrosion/oxidation resistance)

  4. Classification of ceramics by material

    1. Oxide: at least one oxygen atom. Al2O3 (alumina), ZrO2 (zirconia), SiO2 (silica), MgO (magnesia)

    2. Non-oxide (Carbide, nitride): no oxygen atoms. Complex fabrication, Si3N4 (silicon nitride), AlN (Aluminum nitride), BN (Boron nitride), B4C (Boron carbide)

  5. Classification of ceramics by function

    1. Mechanical properties

    2. functional ceramics: optical, chemical, biological

  6. Why is ceramic a useful important material? Ceramics stand when other materials fail.

    1. High hardness, abrasion, and heat resistance

    2. Mechanical & dimensional stability

    3. Mechanical strength at high temp

    4. Corrosion/oxidation resistance

    5. electrical/thermal insulation

  7. Potential application 1: Medical

    1. Bioinert/Bioresorbable

    2. non-allergic

    3. low thermal/electrical conductivity

    4. No artifacts on CT/MRI

    5. Easy to sterilize

    6. High mechanical strength & resistance

  8. Potential application 2: Aerospace

    1. Design freedom

    2. Reduced lead-time

    3. Small scale fabrication

    4. Dimensional accuracy & reproducibility

  9. Process of 3D printing ceramics

    1. CAD

    2. 3D print

    3. Debind / sinter

    4. final product
