Step-by-step guide to making a Sam figure! (or any other figure)
So, here we have a printed PETG plastic model, and it would seem that we can already start painting it, but unfortunately we are still far from that.
I've already cleaned off the big chunks of support material, but there are still a lot of nubs and marks, especially on the base. If I look at it with my bad eyesight from an arm's length away, it looks fine. But if we take a closer look... things aren't too pretty.
I use the hardcore method of picking out the excess with a craft knife, but you have to be super careful not to slice the figure or, more importantly, yourself. Ideally, use a rotary tool with a fine bit if you have one.
I’m using a nail drill (as I said, only hardcore methods here!), but it only has large bits that can't reach the tiny crevices. However, these are lifesavers for the initial sanding of the character model and especially the base, which is shaped like cobblestones, a design choice I have regretted many times. Sanding each little stone is very exciting. But the difference is obvious!
Now you can finish off the surface with a soft buffing bit and then use a large brush or a hairdryer (cold air only!) to get rid of the dust. Congratulations, we have completed the first stage. Next comes the guide coat. We do this to reveal any remaining unevenness and spots that looked normal but are actually messy. It is crucial to apply the primer in a very thin layer otherwise 1) it will drip and be very difficult to remove neatly, and 2) when re-sanding, the primer will leave holes, which are also difficult to fix.
It's very convenient to use a rotating cake stand. It allows you to access the whole figure without touching it with your hands while it's still covered in fresh primer or paint. I wrap the stand in cling film to keep it clean. I use spray primer in a can because it's easier to apply an even, thin layer and prevent the mistakes mentioned above. You probably wouldn't get such smooth results with a regular brush.
Shake the can for 3-5 minutes to ensure the primer is completely mixed. Then go outside or into a well-ventilated room, make sure to wear a mask and gloves! Apply with smooth movements from top to bottom. Don't spray too much at once, use short bursts, wait a few seconds for it to set, then repeat. It's better to apply less in one go and add more layers than to flood the figure. I usually let it dry for about four hours. It's currently -14°C here, so the drying time might vary for you but please give it time!
Now I'm using fine-grit sandpaper (PS30/P320) and continuing to sand everything down by hand. I'm aiming to remove at least half of the layer lines, good luck to me
It is now 6:58 AM as I write this guide, my hands are aching and I should probably go to sleep, so see you in part two! I hope someone found this useful or at least a little interesting (〃゚3゚〃)
