How to attach a resin 3D-printed ornament to a glazed ceramic vase
Two-part epoxy suits this pair because it fills the gap between a curved vase and a flat print, and because resin prints need a properly cured, washed surface before anything will stick to them.
The short answer
Wash and fully post-cure the resin print, abrade both the print and the glaze, then bond with a two-part epoxy. Two things go wrong with resin prints: uncured resin left on the surface after printing acts as a release agent, and a print pressed against a curved vase touches at one point only. Washing and curing fixes the first, epoxy's gap filling fixes the second.
- Difficulty
- Moderate
- Time needed
- 20 minutes work, 24 hours cure
- What you need
- Two-part epoxy, preferably a gel grade, isopropyl alcohol, soft brush, UV cure lamp or sunlight, 120 and 180 grit abrasive, masking tape, pencil
A resin print straight off the plate is coated in unpolymerised resin. It feels dry after an alcohol wash but a film remains unless the wash is thorough and the part is properly cured afterwards. Adhesive applied to that film bonds to a layer that is barely attached to the print itself, and the joint fails at almost no load. A proper isopropyl wash followed by a UV cure is not an optional extra here.
Glazed ceramic needs the same treatment as any glaze: abrade it matt or accept a weak bond. Do it inside a pencil outline so the matt patch is hidden by the ornament.
The third factor is fit. A flat-backed print on a curved vase makes contact on a line, not an area, and the joint is only as strong as the area actually bonded. Either sand a hollow into the back of the print to match the curve, or use a thickened epoxy and let it fill.
Step by step
- Wash the resin print in isopropyl alcohol, scrub it with a soft brush, then wash again in clean alcohol.
- Post-cure the print fully under UV. A tacky print is not ready to bond.
- Hold the ornament on the vase and pencil round it.
- Abrade the glaze inside the line with 120 grit until it is uniformly matt.
- Abrade the back of the print with 180 grit, and sand a shallow hollow into it if the vase is strongly curved.
- Wipe both faces with isopropyl alcohol and let them dry.
- Mix a gel or thickened two-part epoxy and apply it to the print, slightly proud in the middle.
- Press into place, hold for a minute, then support with tape or modelling clay for 24 hours.
What to avoid
Do not bond a print that is still slightly tacky. Uncured resin is a release agent.
Do not rely on thin cyanoacrylate across a curved joint. It cannot fill a gap and will only touch in a few places.
Do not skip abrading the glaze because you do not want to mark the vase. Keep the abraded area inside the footprint instead.
Uncured resin is an irritant and a sensitiser, so wear gloves when washing prints and dispose of the used alcohol responsibly. Do not use this repair on anything intended for food or drink contact.
