  1. Hi I recently 3D printed some sea contains in HO scale, I was going to paint them in LINFOX colours. Since I do not a have smooth surface in which to place a decal and masking for painting may not come out that good. Is there another way to place logos onto an uneven surface. Cheers
  2. Hi I recently saw a vid where the guy mix the paint and thinner in the cup of the airbrush (gravity fed). Would this be normal practice? Even for small amounts? Cheers
  3. Didn't think of that, thanks
  4. Started on the inside of the shed and apart from finding out I can't paint straight lines. Hopefully the cladding will hide the terrible workmanship in the end. So where did it all go wrong, firstly my ambition is more than my talent. I tried masking tape but cutting a 1mm line was proving difficult and in areas resulting in bleeding under the tape, had a 1mm masking tape and tried painting that and sticking it down but that didn't work. Tried free hand with a thin brush - wrong answer and finally a bow pen, the bow pen was actual pretty good with a bit more practice should get some reasonable results. Well onto the structure next. Cheers
  5. Well thing's are not going so well, I'm getting these lines coming through, it's no the supports. I'm not sure what it could be as the model looks fine.
  6. I have gone for 3 ply base, here is the start after priming. Is there a way of getting the wood grain out, I thought maybe using a water down wood putty but I'm, not sure. Also I think I'm in the wrong area, can I get it moved to Scenery, Structures & Transport if that suits. Cheers
  7. Hi I'm finally going to start my re-fuelling shed in HO which will be a portal frame structure. The size of the shed is 115x 565mm so my question is what would be the starting thickness for the base of the structure. So far I have found foam core, but I haven't found anything less than 5mm, plywood 3mm and then acrylic sheets from 1.5mm. I'm leaning towards the acrylic because they can cut it to size so I'll have something square to work from. Cheers
  8. I was thinking that the monocure didn't print detail as well as the anycubic green. I thought that maybe after shaking the monocure you would have to leave it for an 1 hour, so all the air bubbles had a chance to dissapate that way you won't get air pockets under the build plate. I'll see how it goes for structual elements.
  9. The first two prints failed, had a combination of light and heavy supports, which I used for the anycubic green resin, the light supports didn't print where they joined the model. Changed them all to heavy and everything printed but the holes for the bearings, and screw didn't come out right any where there was a small hole was partially filled in. Initial impression the Anycubic green gives a better print. Below are the comparisons on the side frame where the bolster joins there is a gab on the green but not on the monocure and the holes go all the way through on the green I'm hoping that I don't to change the model just to suit the resin. Anyway these were the settings First Last Layer thickness 0.05 0.05 Nom Exposure 12sec 15 Off Time 6.5sec 6.5 Bottom Exposure 60sec 80 Bottom Layer 4 8 Post Cure 30min 30
  10. Hi I've bought a bottle of the Rapid Grey and been searching for some settings on where to start. With the Anycubic Green (that came with the machine) I have been using the following with good results Layer thickness 0.05 Nom Exposure 10sec Off Time 3sec Bottom Exposure 50sec Bottom Layer 4 Post Cure 15min From the Monocure Website Layer thickness 0.05 Nom Exposure 11sec Off Time 6.5sec Bottom Exposure 60sec Bottom Layer 4 The off time is double, the reason is the viscosity it takes longer for the resin to get back under the build plate for the next layer, according to Monocure3D. Are there any thoughts on this? Cheers
  11. So there's a bit of bow in it, I think the detail could be a bit thicker. I'm not sure where to add additional weight, it's a bit light. There's other mistakes with the placement of supports. It's more of test, more thought is required.
  12. Since Les is buying a resin printer and he is going to need resin as well, which resins are people using for bogies and wagon. I've just been using the Anycubic green but is there anything that really stands out.
  13. I should have said HO so it fits with the Photon, (I just have the photon, no S). Well, my first test print (9hrs) went this way, will have to go back to the model and change a few dimensions to the undercarriage and some of the detail on the weagon. Definitely need to think about the type of supports and where they go. I tried to inclued the air tank which as a mistake. So the air tank and brakes wil have to seperate parts and glued on afterwards. The smaller details came out ok once I primed it (the spray painting skills need more work) but I think will make those a bit more defined. There is a slight bow in the side walls when view from above and it bows up in the middle a bit when viewed from the side. Using the Anycubic green resin, is too brittle especially when it comes to taping the threads for the bogies and couplers, I used 2-56 screws for both, but I think I'll use 0-80 for the couplers just to geive a bit more meat to bite into. So will have to look into another type of resin, a few people have mentioned Monocure 3D or alternatively look into casting instead. Not sure if the resins are similar or the casting resin is stronger. Will have to look a weighting the wagon somehow, maybe make a compartment within the undercarriage. All in all I'm pretty happy how it came out, and it even did a few laps of the layout. So far it's heading in the right direction.
