Painting and 3D modelling are two very different art forms that can be used to create a variety of objects, including bottles. Painting a 3D print can add depth and personality to the finished piece, and there are several ways to do this, including using acrylics, enamels, and spray paint. On the other hand, 3D modelling software allows users to create 3D objects from 2D concepts, and tools like Shapr3D can be used to create 3D models of bottles. So, when it comes to the question of do you see a painting or a 3D bottle?, the answer may not be so straightforward, as it depends on the artistic process and medium used to create the final product.

What You'll Learn
Painting 3D prints
Priming is another important step in preparing your 3D prints for painting. A primer coat will prevent the plastic from absorbing paint and improve the paint finish. It also creates a pristine print surface by highlighting imperfections that can be sanded or filled with modelling putty. Primers typically have a flat finish that highlights intricate details under direct light. After applying the primer, inspect the surface again for any imperfections, then apply a final coat of primer. Once the primer is dry, your 3D print is ready for painting.
There are various types of paints that can be used on 3D prints, including acrylics, enamels, and spray paint. Acrylic paints are a popular choice for 3D printed objects as they are water-based, easy to use, non-toxic, and quick-drying. They can be thinned with water for airbrushing and spraying, and they are easier to clean up compared to enamel-based paints. Enamel paints, on the other hand, are known for their harder shell results and high-gloss finishes, but they are more difficult to use and have longer drying times. Spray paint can create smooth surfaces and deep colour gradients, but it may not be suitable for detailed artistic effects. It is important to follow the brand's instructions for the specific type of paint you are using.
When painting your 3D prints, it is essential to work in a well-ventilated area and wear protective gear, such as gloves and a mask or respirator. This is especially important when using spray paint or enamel paints, which may produce toxic fumes. It is also recommended to hang your 3D print or place it on a stand to facilitate the painting process and ensure even coverage. If you are painting outdoors or in a limited space, placing your print on newspaper can help protect the surrounding area from paint. Additionally, using painter's tape can help you achieve precise patterns or section-specific painting.
To create depth and shadow in your paintings, it is recommended to start with a darker layer and then build up lighter layers on top. This technique mimics the way light reflects off objects in the real world, creating different tones. Dry brushing is another useful technique to explore, and there are many online tutorials available to guide you through the process. Experimenting with different techniques and paints will help you add colour and personality to your 3D prints and take them to the next level.

Creating a 3D vintage bottle from a 2D concept
Step 1: Understand the 2D Concept
First, you need to thoroughly understand the 2D concept you are working with. Study the design, and identify the materials, colours, and textures you want to use. For example, if the bottle is made of glass, you will need to consider how light reflects and refracts through it.
Step 2: Choose Your Tools
There are various software tools available for 3D modelling, such as Shapr3D, Autodesk Maya, ZBrush, and Adobe Illustrator. Each software has its own unique features and capabilities, so choose one that suits your needs and requirements.
Step 3: Start Modelling
Begin by blocking out the basic shapes and proportions of the bottle. Use a human model to visualize the scale and size of the bottle in relation to a person. Once you are happy with the proportions, continue refining the shape and volume of the bottle, adding more geometry and details.
Step 4: Texturing and Materials
Create materials from scratch or use built-in options to set up base layers quickly. Start with large primary details and then add secondary and tertiary details. Use a combination of textures and materials to achieve the vintage look you are going for. Substance 3D Painter is a great tool for texturing your 3D models.
Step 5: Lighting and Rendering
Set up your lighting to achieve the desired effects and showcase your bottle. Standard 3-point lighting is a good starting point, but you can adjust and add lights as needed. Marmoset Toolbag is a great tool for rendering high-quality assets.
Step 6: Refine and Critique
Regularly seek feedback and critiques from experts and communities to improve your work. Showcase your work-in-progress and explain your process to receive valuable insights and suggestions.

Using Adobe Illustrator to map 2D artwork to a 3D object
Adobe Illustrator offers a range of tools to map 2D artwork onto a 3D object. This process involves adding graphic artwork to each surface of a 3D object. Firstly, it is important to note that you can only map 2D artwork that is stored in the Symbols panel. These symbols can be any Illustrator art object, including paths, compound paths, text, raster images, mesh objects, and groups of objects.
To begin the process, you can either create your own 2D artwork or download a sample 2D artwork. If creating your own, simply draw your desired artwork on a piece of paper and import the raster image into Illustrator. To import, go to File > Place in Document. Then, select Object > Image Trace > Make to trace the image with default options.
Before applying 3D effects, it is recommended to explore the various options available in the 3D and Materials panel. To access this panel, click Window > 3D and Materials. Here, you can view the different lighting, intensity, and shadow effects that can be applied.
Now, you can start applying 3D effects to your 2D artwork. Click Effect > 3D > Extrude & Bevel to access the 3D and Materials panel. Here, you can set the depth, twist, and taper of the object. You can also adjust the rotation and perspective to achieve the desired view.
Additionally, you can add multiple graphics to your 3D object. To do this, select the 3D object and click the graphic thumbnail from Graphics > All Materials & Graphics. Alternatively, you can drag and drop artwork to the 3D panel.
By following these steps, you can effectively use Adobe Illustrator to map 2D artwork onto a 3D object, allowing you to create stunning dimensional designs and illustrations.

Painting with light
When painting with light, the photographer decides what to illuminate and what to keep in shadow. They also control the angle, texture, feel, and colours in their photo. Every brushstroke of light builds the final image, and the process is said to be highly addictive, fun, and rewarding.
To create a 3D effect in a painting, software like Adobe Illustrator can be used. This software allows users to create 3D objects by extruding and revolving 2D shapes. Lighting effects can be added to these 3D objects, with options to add multiple lights, adjust light intensity, change shading colours, and move lights around the object for dramatic effects.
Additionally, 3D prints can be painted to add depth and personality. Before painting, it is essential to sand and smooth the surface of the print to ensure a nice finish. Acrylic paints are a popular choice for painting 3D prints as they are water-based, easy to use, quick-drying, and non-toxic. Enamel paints can also be used but have a longer drying time and require mineral spirits for thinning.
Overall, painting with light, whether in photography or 3D art, involves using light sources and illumination techniques to create unique and visually appealing effects.
