Today, many 3D printing<\/a> enthusiasts are intrigued to discover all its functional capabilities and employ them for their pleasure. Their interest in 3D technology’s potential has constantly increased for the last several years.<\/p>\n\n\n\n Although cool stuff, 3D printed models are usually monochromatic. Learn how to paint 3D prints to look more like their prototype. You can use any quality acrylic paint and a paintbrush or an airbrush tool, but you should first prepare the model (sand and prime it). The entire process of smoothing 3D prints can be time-consuming, but it’s worth the effort.<\/p>\n\n\n\n In our guide on painting 3D printed models with the best paint for 3D prints, you will learn how you can airbrush your projects and paint them with acrylics to create stunning glossy and smooth surfaces to adorn your figurines.<\/p>\n\n\n\n But before you begin painting 3D prints, it is essential to prepare your 3D printed model, make it smooth and fill in every tiny hole with a primer and putty. Below, see more details on each step.<\/p>\n\n\n\n Since sanding and priming come in partnership when you are preparing your 3D prints for painting, you should ensure you have these materials in hand:<\/p>\n\n\n\n Smoothing 3D prints is an important step if you wish to achieve a polished surface<\/a>. And since many complex SLA and FDM 3D printing objects use supports to avoid the collapse of overhang parts, it is necessary to remove the support material in the first place. You can use a knife, pliers, rotary tools or razor blade to do this step carefully.<\/p>\n\n\n\n After this, the surface of the model will be rough. So, it is advised to sand it to make it polished. It is how to smooth 3D prints at home.<\/p>\n\n\n\n Usually, before painting PLA 3D prints or ABS projects, you will notice visible lines and patterns from printing, depending on the layer height. These lines can also be sanded out with medium, fine, extra-fine sandpaper for 3D prints. You can start with 220-320 grit sandpaper to carefully smooth the surface and then switch to 400-600 grit.<\/p>\n\n\n\n This type of work is time-consuming and requires patience on your side. However, the final result is worth all your efforts!<\/p>\n\n\n\n Once done with the sanding process, you can proceed to the next step of choosing pain for 3D prints and preparing 3D printed models for painting. But make sure to wash the dust away before proceeding.<\/p>\n\n\n\n Primer paint is used to prepare the 3D printed parts for further painting. It is used to ensure better adhesion of paint to the model surface and covers all other minor defects of an object, filling in holes and fine lines to create a smooth 3D print.<\/p>\n\n\n\n If your model comes with imperfections, holes, cracks and other issues, you can use the neutral grey primer to highlight all the problems and prepare your 3D prints for sanding afterwards. Besides, for ABS, TPU, PLA smoothing, you can fill all the problematic parts and lines with modelling putty.<\/p>\n\n\n\n If you wish to paint 3D prints with acrylics, you can apply black primer (for example, Krylon) beforehand.<\/p>\n\n\n\n Depending on the colour of your 3D prints, you can apply from one to five coats of primer. Let your project dry between coats. Also, apply a primer in horizontal or vertical lines and keep to the primer application pattern along with the entire model.<\/p>\n\n\n\n Several hours after applying the last primer coat, you will have to sand the model again with fine sandpaper for 3D prints after the primer dries out completely. This way, you can smooth the 3D print surface before painting and eliminate any roughness that appears during the primer coating procedure. Simple final polish can be handy and help you achieve a more professional result.<\/p>\n\n\n\n Airbrush is a technique of applying paint or dye on a surface, in our case on a 3D printed model. An airbrush is an air-operated tool that sprays paint on a 3D print (or another object) in multiple, tiny droplets. The person that manoeuvres the tool controls the amount of paint that gets applied to the surface of the object.<\/p>\n\n\n\n This technique allows blending two or more colours, with one colour gradually becoming another colour. Airbrush is vastly used for paper paints, murals and other types of painting. When you look at some graffiti and spray-painted posters, you can see that such projects lack details and beautiful effects. Still, spray painting 3D prints with the proper technique can create stunning gradients and smooth creations.<\/p>\n\n\n\n The airbrush technique has become very popular among hobbyists and 3D printing enthusiasts because of its capability to apply finer coats of paint on 3D printed models. This technique is preferred because it allows producing various effects, like opaque, stains, which are harder to be produced by hand-brushing. Painting 3D prints using an airbrush technique might sound challenging, but it is not impossible. It takes a little effort and some imagination to finish the object.<\/p>\n\n\n\n So, once you finish smoothing 3D prints and priming your project, you can spray paint your 3D print. This technology is the quickest way to create even colour shades across the surface.<\/p>\n\n\n\n Start building up thin layers of spray paint and apply multiple coats over areas that have been primed. To achieve thin coats of paint, you will need to hold your airbrush tool or paint bottle relatively close to the areas and move quickly from one part to another one. If you learn how to paint 3D prints and wish to create beautiful 3D models, use a rotation station to move the print around and keep your layers thin and even.<\/p>\n\n\n\n If you plan to add different paint colours, make sure to mask areas to avoid spraying paint over them. Also, when you add more than one paint coat ensure you have buffed and polished it after each coat. This way, you will create a smooth glossy area that will look superb once you apply the clear coat.<\/p>\n\n\n\n Since primer is of a neutral shade, you can easily block it by adding a colourful undercoat (it is also known as a base layer). This way, you will enjoy a beautiful richer colour.<\/p>\n\n\n\n When you choose the spray painting 3D prints technique, you will have to apply two or three thin coats of paint to cover the model’s surface thoroughly. Ensure to complete your airbrushing in one session. This way, the layer will be even and nice.<\/p>\n\n\n\n Before applying a layer of spray paint on your 3D printed items, you should add the undercoat to create lifelike dark tones (shades) to make the figurine or model look more beautiful. Usually, it is best to use black paint for the first undercoat.<\/p>\n\n\n\n To make a 3D print in PLA or resin even more real, you will have to add lighter colours (white is the best) as a topcoat.<\/p>\n\n\n\n And between the layers, it is best to mask the areas to paint the coats you only wish to add now. However, you should only leave the masking tape for one or two days.<\/p>\n\n\n\n The thinner the coats you apply to a 3D printed model, the more its undercoat will be seen through. So, when working with thin coats, you can create a beautiful effect with dark and light shades.<\/p>\n\n\n\n Only remember that between the coat applications, you should ensure that the colour has enough saturation (just as you imagined it).<\/p>\n\n\n\n After applying your colourful coats of spray paint for 3D prints, you can add a clear coating. You can add one or even two thin layers of clear coat to create a beautifully polished surface.<\/p>\n\n\n\n Some 3D printing enthusiasts love to polish the clear coat using an appropriate grit polishing cloth. Others prefer adding an extra protective layer of wax.<\/p>\n\n\n\n No matter what method you choose for spray painting 3D prints, ensure enough time for your 3D printed model to completely dry. It is great if you can set it aside for a week or even longer to give the paint time to harden.<\/p>\n\n\n\n Not everyone loves airbrushing technique. In this situation, you will need acrylic paint for 3D prints, paintbrushes in different sizes (from small to big), a palette for colour mixing, water and, of course, a 3D printed model.<\/p>\n\n\n\n For painting 3D prints, you don’t need any fine art paints or hardware store paints. Even though they can be suitable for rough surfaces, they will not be great for a 3D printed model.<\/p>\n\n\n\n Acrylic paints are perfect for painting ABS, PU, PLA<\/a> 3D prints and colouring the Nylon filaments<\/a>. Remember that a lot matters how you prepare the 3D printed objects for painting (ABS, PLA smoothing). And an essential step to finishing the model is priming it. There could be flaws if you only apply paint coat by coat without polishing the 3D printed model. Thus, it is essential to hide various support marks, 3D printed mesh triangles and layer lines (if any) before you start painting 3D prints with a brush.<\/p>\n\n\n\n With various acrylics brands, you can go with your favourite company, such as Vallejo, Golden, Blick Studio, Arteza, etc. Professional 3D printing enthusiasts work with wet palettes when painting big 3D prints for days in a row.<\/p>\n\n\n\n Painting 3D prints with acrylics is relatively easy. You apply the paint directly to your 3D printed model and dry each coat. Use a reference or fantasize your shades to create a unique and excellent work of art.<\/p>\n\n\n\n Be artistic and ensure to dilute the paint. Also, try to apply a layer and give it time to dry before you continue. Here is some advice:<\/p>\n\n\n\n P.S. Instead of acrylics, you can use enamels, oils, lacquers and water-based brands to paint PLA, ABS, TPU and other filaments. For example, it usually takes up to 5 days for the high-quality oil paint to dry on 3D printed models.<\/p>\n\n\n\n And as a whole, it should be fun painting 3D prints with any type of paint. You can achieve a stunning result after sanding and priming the project.<\/p>\n\n\n\n Besides, it is possible to mix your painting techniques and paint brands. Some users, for example, like to paint their 3D prints with acrylics and afterwards add an oil wash to achieve a stunning weathering effect to reveal the underneath coats.<\/p>\n\n\n\n When you master how to paint 3D prints (resin, PLA, ABS, PTU, etc.) with acrylics or airbrushes, you can think of adding some realistic effects. Using opaque, silver, golden, antique shades, you can achieve retro, antique, worn-out, sparkling outcomes.<\/p>\n\n\n\n Enthusiasts who like painting 3D prints with golden and silver paints can use spray cans (or airbrushes) to spray the top layer where needed.<\/p>\n\n\n\n To finish your work, you can apply a thin coat of matte or gloss sealer. It is the best way to protect the paint and your creativity for years ahead.<\/p>\n\n\n\n When choosing your clearcoat brand, check what different manufacturers recommend and select the brand compatible with your paint coats.<\/p>\n\n\n\n For example, when you are painting a 3D printed tank<\/a>, you might want to add worn out and rush effects. It can be achieved by applying the rusty paint to one of the bottom coats and then slightly scraping off the topcoat so that the wanted result can peer through.<\/p>\n\n\n\n Use your imagination, and don’t be afraid to experiment.<\/p>\n\n\n\n See how DIY 3D printing<\/a> is becoming a very popular trend nowadays and how delightful the all process can be.<\/p>\n\n\n\nHow to Paint 3D Prints<\/h2>\n\n\n\n
