The 3D printer does not produce objects exactly as we would like them to, which is why it does what is commonly called post production. As soon as they are removed from the printer, the objects may be defective, so we have to finish them, smooth them, remove the residues of the media, etc.
Once the care of the surfaces has been completed, we can also colour it with different techniques or create special effects.
To do this we need a real arsenal of tools and accessories. Today I want to list those that I use normally, so that those who want to get into this fantastic hobby, have a good starting point.
Here are a number of accessories that I use daily.
Post Production: accessories for perfecting prints
- Cutter: it is a tool that can always be useful, especially those with a slimmer shape, to eliminate small imperfections due to the presence of supports or smears.
Available on Amazon.
- Chisels: Comfortable set of chisels to eliminate any kind of imperfection, in the set you can find 45 degree points, flat curves, small and large. They can also be used to detach the prints from the plate, in case they are glued. Amazon.
- Windproof lighter: very useful to eliminate spider webs due to stringing, without blackening the object as happens with normal lighters. Use with caution and without lingering too long in a single point, doing rather several steps alternating with small pauses of a few seconds. Amazon.
- Dremel o similar: The Dremel with its different tips is very useful to improve different aspects of your objects, it can help you to file as well as to make holes or simply enlarge them. Care must be taken to adjust the speed because at a high speed it could melt the plastic. You should also wear protective glasses because of small fragments that could splash while using this tool. Amazon.
- Set of accessories for Dremel or similar: the more accessories we have, the greater our possibilities will be. Amazon.
- Goldsmith’s file set: Goldsmith’s files have different shapes (triangular, square, round and other shapes) and are very thin and tapered. They are perfect for reaching hard-to-file areas by other means. Amazon.
- Abrasive paper: it is always good to have different grains to sand your objects and have a smoother surface. Amazon.
- Pyrograph: I use the pyrograph to smooth out very damaged or discontinuous points. The hot and small tip allows you to heat the plastics and “remodel” them to eliminate defects or possibly close small unwanted holes. Amazon.
- Abrasive sponges: Abrasive sponges are another useful tool for sandblasting points or difficult surfaces. Amazon.
- Jewellery pliers: pliers with different tips and sizes are useful for the removal of supports and possibly for the removal of small defects. Amazon.
- Spray filler: essential for the post-production of many objects, to be used as a filler between layers and as a basis for sanding. Amazon.
- Spatula set: Useful for shaking large surfaces but also to detach the prints from the plate. Amazon.
- Putty: the putty can be useful to close medium-large holes maybe caused by excessive use of dremel or sandpaper. Amazon.
- Glue: to put together objects printed in several parts or to fix your prints to supports you will need glue. Amazon.
- Hot glue gun with stick: for quick and effective repairs. Amazon.
- Primer spray: primer for plastics to be sprayed on objects as a basis for painting both spray, manual, and with airbrush. Amazon.
- Airbrush: an object that can make a real difference to your prints. It will allow you to quickly color many objects and with practice you can give many effects and shades with little effort, usefull for post production. Amazon.
- Airbrush colours: obviously the airbrush needs special colours. Amazon.
- Airbrush cleaning set: set of needles and brushes for cleaning and maintaining the airbrush. Amazon.
- Airbrush cleaning fluid: liquid to be used both to clean the airbrush between one colour and another, and to clean it completely when you finish using it. This is essential because the airbrush must be kept clean for proper operation. Amazon.
- Airbrush Thinner: Liquid to dilute airbrush colors. Can be used in different percentages to obtain more or less opaque colors. Amazon.
- Brush set: Indispensable for touch-ups and details but also for small objects. Amazon.
- Acrylic colors for modeling: if you have to paint details or small objects these are what you want to make your prints 3d the leap in quality. Amazon.
- Masking tapes: when you paint using airbrush or spray cans the tapes will be of great help to avoid painting and dirtying already colored areas of your object. It’s used in post production but can be used as build surface also. Amazon.
