XTC-3D® is a protective coating for smoothing and finishing 3D printed parts. It does not melt plastic. Two liquids are mixed together and brushed onto any 3D print. Coating self-levels and wets out uniformly without leaving brush strokes. Working time is 10 minutes and cure time is about 4 hours (depending on mass and temperature). XTC-3D® cures to a hard, impact resistant coating that can be sanded, primed and painted. Adding colors and metal effects is easy.

  • Inexpensive to Use: 1 oz covers 100+ square inches.
  • 90% Time & Labor Savings: XTC-3D® fills in 3D print striations and creates a smooth, high gloss finish. The need to post finish is almost eliminated.

Coat any 3D Print Surface: XTC-3D® can be applied to both SLA and SLS prints. It works with PLA, ABS, Laywoo, Powder Printed Parts and other rigid media. It also can be used to coat EPS, EPDM and urethane foam as well as wood, plaster, fabric, cardboard and paper.

XTC-3D® does not contain VOC's, phthalates or phosphates.

Perfect for finishing PLA prints

I bought this to try making board game bits trays smoother and kinder to cardboard/plastic that was getting caught on striations and layer lines. A single coat of this already made such a fantastic difference, but once I did the second the smoothness was like no other.
Highly recommend. Have used about 30ml (final combination vol) to do 2 layers on 5 decent sized trays so even this small bottle is going to last me a while.
Only feedback would be to get more than one sponge brush as it's unlikely anyone would use this whole bottle in one 15minute session.

Gets the done…. And then some!

I bought a kit to clean up up a 3d printed model i had made, after only one coat the finish is almost perfect ( some run lines ) once cured it sands smooth with some wet 600 grit sand paper.

Definitely wear gloves!!

PLA 3D print smoothing made Easy

I was really surprised how well XTC-3D worked on my 3D Printed parts. The ability to reduce my post-processing time of parts was amazing. All parts came out really shiny and super smooth. The XTC-3D ability to fill in gaps, pin holes and seams was amazing. Sanding was a breeze after this. The absolute minimum amount was used as the saying goes, "a little goes a long way". The amazing properties of XTC-3D are a must for COS-PLAYERS and others in the 3D print community. Well done SMOOTH-ON, a fantastic product!

What a great insight into this product. Thanks for the feedback!
