discussion Help with 3D Printed Models Please

[Airborne01]

This may be a 'how long is a piece of string?' type question but here goes: I will soon attempt the German Motorcyclist for one of the GBs; it's a 3D print in a light grey resin and covered in copious amounts of release agent (?). My questions are as follows:

1. What is the best solvent for removing the release agent? (The fine detail looks very fragile so I think the toothbrush is out!)
2. Adhesives. Will ordinary CA work or does it need something else?
3. Fillers. What/which fillers are recommended in the light of experience?
4. Primers. I use Tamiya primers ordinarily, is this still suitable?
4. Lastly, are there any other recommendations/pitfalls/tips that will help this anxious novice?
Thanks in anticipation.

1. IPA isopropyl alcohol,not Brewdog...
2. Yes
3. Any normal filler should be fine
4. Most likely yes. I use Halfords rattle can with no problems
5. If the supports are still attached use snips rather than a scalpel. It takes longer but reduces the risk of destroying detail
Looking forward to this. If you have any problems message me because I have bought the files and I can easily print you a section if necessary
All the best

If you have any uncured resin, wipe with IPA and then 20 mins under a UV light should sort it .
A nail polish dryer (if swmbo has one) or a little UV torch - I have one for curing UV glue.

Thanks for your reply Neil, and for your kind offer of mistake remediation! Greatly appreciated.

1. are you sure its a 3d print , or is it a resin model cast from a 3d printed master ?

The reason I ask is that no 3d printed model should have any residue on it when given to someone/bought from someone , but many of the ''cast'' versions do have release agent on them ?

 

[Airborne01]

Probably the latter then Gary, i.e a resin cast - Blimey, every day's a school day here! Thanks very much

I'm pretty sure it's a print. The whole point is that it's way too complicated a model for casting
Are you posting any pics Steve?

and covered in copious amounts of release agent

If it is a 3d print then that's sort of disturbing for a commercial product... Make sure you don't touch it with your hands and wash them well if you do. 3d resin in liquid form is a health issue.

Click on the ">>" to see the pictures of the parts...

That's 3d printed, small piece on the right has still supports attached.

seconded.
use disposable gloves

Thanks Gents for your replies; I've been working away again so I apologise for the delayed response - so, it's scarily fragile and complicated and now a health hazard - mmm! Oh well, onwards and upwards! Starting very soon so wish me luck! I will definitely post up progress reports
