There are so many airbrush models out there knowing which ones are best for scale model building and detailing miniatures is difficult. With the flood of copycat models, this makes it especially hard. That is why we created this guide to inform you on what scale model builders look for as well as listing the best airbrushes for models and miniatures from top manufacturers Iwata, Badger, and more.
After building scale models for years including cars, warships, and fighter planes, nothing has improved the visual quality and realism of the models as an airbrush setup. I first became interested in getting an airbrush for the plastic models and miniatures I create after seeing a battle scene a friend created. It was so incredibly real looking and he attributed it mostly to airbrushing the models and landscape features.
I immediately started looking for the best airbrush for models I could find. I quickly realized there was a lot to learn before I made a purchase. After weeks of research I had a good idea of what I needed to look for in the various airbrush systems available. This knowledge was invaluable but I needed to know as much about the techniques and styles used in model airbrushing as I did the actual airbrush units.
One thing you should know is that the practice of airbrushing models or miniatures takes a lot of time and practice. That shouldn’t discourage anyone as this is an extremely enjoyable and gratifying activity. It is also a ton of fun learning to airbrush and once you get the hang of it will elevate your model building hobby to the next level.
When searching for the best airbrush kit for your model building take into account what type of models you mostly work with, whether they are plastic, wood, or other material. Landscaping and terrain airbrushing will have slightly different requirements than those of vehicles and miniatures. That said, check out the guide below to learn all about airbrush systems which should make choosing a little easier.
How to Choose: A Guide to Airbrushes for Modeling
There are several types of airbrush systems as well as different features and attributes of an airbrush as well. Not all airbrushes are made with the same capabilities, for instance an illustrator’s airbrush is not capable of handling paint as it is made for ink. It is important that you get the proper airbrush system that modeler’s can use with acrylic and enamel paints.
The other aspect you undoubtedly will take in to consideration is price. The good news is modeler airbrushes are among the most affordable. You will certainly get what you pay for but you can certainly purchase a very good and capable system for under $200. The three most popular brands to get familiar with are Iwata, Badger, Paasche, with Harder & Steenbeck and Grex also being popular.
Finally, if you aren’t purchasing an airbrush kit which includes several accessories, you will need an airbrush compressor to power your airbrush system. This is arguably one of the most important pieces of equipment which I will be writing a guide for in the near future.
There are several different aspects to how an airbrush may handle. This includes how the airbrush is controlled, how paint feeds into the nozzle and out, as well as how the paint is atomized or mixed with air before landing on its intended medium.
An airbrush unit will be manufactured in a combination of the different styles of control, paint feed, and atomizing methods. I will detail differences of each and what airbrush may be best for scale model builders but ultimately it should be the preference of the artist.
Single-Action vs Dual-Action Airbrush
The action of an airbrush simply describes how the paint and air flow are released by the lever or button. This, in part, determines how much control you might have while painting your models or miniature figures.
- SINGLE-ACTION AIRBRUSH: This type of airbrush only allows the user to control the airflow by pressing a trigger or button. It does not allow real time adjustment of the paint flow which is instead done by adjusting the needle depth in the nozzle. Users must stop any painting to make adjustments, this can be cumbersome. The benefits are that it is better for beginners as it easier to learn with and maintain. I do notice modelers usually end up upgrading to Dual-Action pretty quickly.
- DUAL-ACTION AIRBRUSH: This type of airbrush allows users to control both air and paint flow with the trigger/button. The first action of pressing the trigger down allows air to flow through the airbrush. The second action of sliding the trigger back will allow paint to flow through. The further you push down or back the increased paint or airflow. This allows for continual adjustment but requires much more practice to perfect this method but is more versatile.
Consider how much on-the-fly or fixed paint and air flow you will need when choosing between the two. This is what will most be impacted by the two methods.
Gravity vs Siphon Feed Airbrush
The other major factor in choosing an airbrush is how the paint is delivered. Both methods have advantages and disadvantages so choose the method that works best for your needs and use.
- GRAVITY FEED AIRBRUSH: This method of paint delivery places the paint cup at the top of the airbrush. Gravity alone pulls the paint into the airbrush atomizing chamber. Gravity fed chambers allow for a lower working air pressure which can be an advantage when painting fine lines and details on miniature figures while avoiding over-spray.
One possible drawback to the gravity fed style is the smaller cup size for storing paint. The smaller cup size, depending on your project, may require you to refill your paint supply often when painting larger scale models.
- SIPHON FEED AIRBRUSH: Siphon fed airbrushes have the paint bottle attached below the unit which feeds a tube into the paint container connecting the supply to the mixing chamber. When air passes across the tube in the mixing chamber it siphons the paint in.
The siphon fed airbrushes usually allow for a larger amount of paint storage. This could be advantageous to painting something like a larger battle ship. Siphon fed units seem to use slightly more paint and require slightly more clean up time.
The amount of your paint supply as well as how much working air pressure is used allowing for fine lines or covering large spray areas quickly is what you should consider. Cup sizes will range for around 0.9 ml up to 15 ml with siphon feed.
Internal vs External Mix Airbrush
This refers to where the paint mixes with the air or where it is atomized. Where it is mixed will have some effect on the finish of the paint. Aside from effecting finish, internally mixed also requires an extra cleanup step although this is minimal.
- INTERNAL MIX AIRBRUSH: When paint enters the chamber of an airbrush and mixes with air, this is what is referred to as internal mix. This internal paint atomizing usually produces a smoother and finer finish which is preferable to model builders.
- EXTERNAL MIX AIRBRUSH: Externally mixed paint does not enter the airbrush. Instead paint flows along the outside of the nozzle and is then atomized with the air as soon as the airstream exits the nozzle.
The external mixed airbrushes usually produce a flatter finish that isn’t as smooth. This can be remedied somewhat by experiment with your paint mix until you get it just right.
Airbrush Parts and Accessories
An airbrush is only as good as the parts and accessories that accompany it or are used on the inside which affect performance.
Parts do wear out as well and can be interchangeable to produce different performance in the airbrush so it is wise to choose a reputable brand that you will have easy access to replacement parts.
Airbrush needles are going to determine how fine are broad your airbrush lines will be. The smaller the needle the finer the lines you will be able to achieve but this is only to an extent as the effect will diminish the smaller you go.
Fine needles also are more prone to clogging with thicker paint mixes like acrylic paints and some enamel paints. The finest needles are usually best left to illustrators using inks. Typically the best size airbrush needle for modelers to start with is going to be around .5mm as this will produce a great all-around spray.
Note that the needle and nozzle combination will determine the final effect. After a bit of practice and familiarity you will determine what ultimately works best for you. A good rule is larger needles (0.5mm and greater) for less detailed work and smaller needles (less than 0.5mm ) for more detail though skill can sometimes overcome these limitations.
The nozzle is another component that will affect the spray effect pattern. Short nozzles will usually deliver a wider pattern that can cover more area. The longer narrow nozzles will produce much narrower spray lines used when you need to spray precision lines. Most nozzles are sold in kits with a compatible needle but if you are purchasing the nozzle alone, ensure compatibility.
There are different sources one can use as a compressed air source whether it is a large bottle of compressed air or disposable can. The most reliable and convenient source is usually going to be an airbrush compressor. This is arguably one of the most important pieces of equipment aside from the airbrush itself.
The airbrush compressor needs to provide a steady air supply while maintaining a consistent air pressure and air flow. This is important in spraying the smoothest and most precise paint lines. Any fluctuation, whether in pressure drops or pulses, will cause issues.
Aside from providing consistent pressure and supply, look for a quiet compressor. Nothing can be more distracting while painting than having to deal with a loud compressor kicking on and off as it supplies you with air.
Essential Airbrush Accessories
Below are general list of items you will need in addition to your airbrush unit to ensure you are able to maintain your unit and keep it operating for years to come. Cleaning your airbrush thoroughly is one of the most important things you can do to ensure a long working life.
Keeping moisture out of the unit via a moisture trap is another important thing to do. This will minimize any corrosion inside the airbrush and the working parts.
- Airbrush Cleaner
- Airbrush Cleaning Brushes
- Moisture Trap
- Fittings and Connectors
- Miscellaneous Spare Repair Parts
Aside from keeping the unit clean and having the parts above to be able to operate your airbrush having a spare kit for airbrushes will ensure minimal downtime should any issues arise. These kits usually have various gaskets, bushings, and springs that make up the internal parts of an airbrush. Highly advisable to have one on hand. Final tip is to buy an inexpensive ultrasonic cleaner to clean the airbrush after every paint session.
