Ceramic FDM Filament

Porcelain Ceramic Filamet™ — 1.75 mm, 0.5 kg

Print real porcelain on the FDM printer you already own. After kiln firing in the cone-6 range, your print is genuine fired porcelain — glazable, waterproof, and food-safe with the right glaze. The traditional ceramic of art pottery and electrical insulators, now a CAD-driven workflow.

Real porcelain, printed on a desktop FDM

Porcelain Ceramic Filamet™ loads 48–52% porcelain into a printable polymer matrix. After cone-6+ firing in any pottery kiln, the binder burns out and the porcelain particles vitrify — producing a dense, white, vitreous ceramic body that behaves exactly like wheel-thrown or slip-cast porcelain at every step downstream.

Porcelain has been the gold-standard ceramic for art pottery, decorative ware, fine tableware and electrical insulators for over a thousand years. With Filamet™ you can take CAD geometry — lattice cups, parametric tiles, intricate jewelry, custom insulators — straight to a fired, glazable porcelain part without throwing, casting or moulding.

A bridge between studio pottery and 3D printing. Print, fire, glaze and re-fire using the workflow already in your studio. The bisque print integrates cleanly with cone-6 glazes, underglazes and decals — nothing about the back end of the process changes.

How it works — the 4-step process

1

Print

Print on any FDM printer with a 0.6 mm hardened steel nozzle. Behaves much like PLA at the extruder — minimal warping, easy first layer.

2

Pack

Nest the green print in alumina or silica ballast inside an alumina crucible — supports the part during binder burnout and vitrification.

3

Sinter

Fire to ~1200°C+ in a pottery kiln — cone 6 is a good baseline, cone 10 if your studio runs higher.

4

Glaze & Finish

Glaze and re-fire using your usual cone-6 glaze workflow. Expect ~15–20% linear shrinkage — scale models up ~120–125%.

Why porcelain

True vitreous porcelain

After firing the part is real porcelain — dense, white, vitrified, low porosity. Behaves identically to wheel-thrown porcelain in every downstream step.

Glazes with standard recipes

Use any cone-6 glaze, underglaze, slip or decal. The bisque print accepts glaze the same way a slip-cast bisque would.

Food-safe with food-safe glaze

A vitrified porcelain body topped with a properly fitted food-safe glaze produces tableware that meets the same safety bar as commercial pottery.

Geometry beyond the wheel

Lattices, undercuts, asymmetric forms — CAD opens up shapes that are difficult or impossible at a wheel or in a slip mould.

Electrical insulator chemistry

Porcelain is the original electrical insulator — high-voltage bushings and spark-plug bodies are still porcelain. Same chemistry, on demand.

Printing tips

  • Lighter than the technical ceramics — tolerates faster speeds
  • Filawarmer recommended for prints over 4 hours
  • Direct drive preferred but Bowden works for shorter prints
  • Scale models up 120–125% to compensate for sinter shrinkage

Common applications

  • Studio art pottery and sculptural ceramics
  • Custom tableware (with food-safe glaze)
  • Decorative tile and architectural ceramics
  • Electrical insulators and bushings
  • Porcelain jewelry and small giftware
  • Educational ceramics and student projects

Frequently asked questions

Can I use the finished part for tableware?

Yes — once sintered and topped with a properly fitted food-safe glaze, the part is real porcelain tableware. Treat it as you would any handmade pottery: vitrified body, food-safe glaze on all food-contact surfaces, fired to maturity.

Do my existing cone-6 glazes work?

Generally yes — the bisque-fired print is a porcelain body, so any glaze with the right cone-6 fit should behave normally. As with any new clay body, run a small test tile before committing a large piece.

What kiln do I need?

Any kiln capable of cone 6 (~1200°C) or higher will work — the bar most studio pottery kilns clear comfortably. The TVF FireX covers porcelain firing with headroom for the technical ceramics if you expand later.

How does this compare to other ceramic Filamets?

Porcelain is the studio-pottery and decorative-ware ceramic. Zirconium silicate is a technical refractory for insulators and kiln furniture. Pick porcelain for art, tableware and traditional ceramics; pick zirconium silicate for high-temperature engineering work.

Will the print survive being thrown on a wheel post-print?

No — the green print is a polymer composite, not a workable clay. Once it has been fired and glazed, however, it behaves like any other piece of finished porcelain and integrates well with hand-finished components in mixed-media work.

What else you’ll need

TVF FireX Sintering Kiln

Comfortably fires porcelain at cone 6+ and grows with you into technical ceramic schedules.

Other Ceramic Filamets

Zirconium silicate and silicon carbide round out the ceramic range — useful when porcelain is not the right body for the job.
