Ideas on how to get a better surface?

Do I have to sand or is there some magic I’m not aware of?

@CaptainFlintlockFinn are those resin support marks? If so you could try reorienting your model to reduce the number of supports needed. Possibly experimenting with the number, spacing and thickness may get better results. I'm no expert but have found it helps sometimes.
They are indeed support marks. I’ve already messed with orientation and this is the position with the least marks so far. I haven’t really messed with support settings yet. Thanks for the idea.
Thanks!
Everything I found said that cured resin is inert. I did see that there are biocompatible resins out there but they seem to be mostly used in dental applications. I’ll keep searching though.
10-4. I hear you.
For labs sells a biocompatible resin for medical use. I’ll probably end up switching to that.
@Piecemakers3Dprints @CaptainFlintlockFinn as a one time chemist I'd agree that there is a real possibility some trace materials in the resin causing some harm in prolonged contact. The resin may be set but could potentially leach some of the other materials such as unreacted ingredients, catalysts etc. In the same way that cheap jewellery can release alloying metals that cause irritation. A dermatologically safe varnish seems a sensible call.
