Additive vs Subtractive; 3D Printing Basics June 28, 2022 Admin One of the most exciting pieces of technology to commercialize over the past decade or so has been within 3D printing as it promises plenty of change in the future from sustainable building and manufacturing processes to a change in home hobbies including model making and the like – some of the most impressive projects in the world already exceed expectations such as those shown from Dubai 3D Printing projects as it leads the world for the industry, but there are plenty of exciting home projects emerging too. For those looking to get started with 3D printing, there are two fundamentals to understand, and could change the 3D printing experience too. Subtractive printing – As the name would suggest, subtractive 3D printing is the act of removing material to create the end product, for older devices this may have been the act of starting with a larger block of material and working the plan around how to remove this material, similar to the way many CNC machines currently work – whilst many modern printers work on the additive process now, it is still a big part of the process as subtractive printing remains an important part of any larger project, and still plays a role in smaller scale printing too. What's the Difference Between 3D Printing and Additive Manufacturing? | ERP Solutions & Software From K3 Syspro Additive printing – This process is the opposite, instead working by building layers of material to reach the end product – this requires a larger spool of material that is gradually fed through, and the project is built this way. This can be a slow process for the larger projects, but has revolutionized the way some process take place, but the slower process can be fairly cheap with the energy cost being the defining factor for some instead which has helped change expectations for much larger projects too. Both will still continue to be widely used throughout the manufacturing process for different purposes – finished products will often come from a subtractive approach whether through 3D printing machines or more likely through CNC options, particularly for higher volumes where speed is key, but more specialized parts that are required to save weight or have very intricate designs are better suited for additive manufacturing, and this is where 3D printing is really shining as speed isn’t necessarily a factor. For those looking to take advantage of home style manufacturing, research both to see what process fits personal needs better whether a more expensive process is manageable, or if slow and steady is a better fit.

How to Choose the Best Cargo Trailer For You

Cargo trailers are undoubtedly the best way to transport items safely. It is not a good idea to purchase a new or used cargo trailer before you do your research. You don’t have to do what someone else did, just because they invested in an enclosed trailer measuring 8.5×20 doesn’t mean that you should.

These trailers come in many sizes, shapes, and features. You should spend quality time looking for the right one for you. We have compiled the following points to help someone who is thinking about buying a cargo truck trailer.

The usage

If you don’t know how you intend to use the cargo trailer, a cargo trailer won’t help you fulfill your purpose. A small business does not need a large trailer. A large trailer is required if you need to transport heavy or large items.

The cost of a closed cargo trailer is more expensive than open cargo trailers. An enclosed trailer will be more suitable if the items being transported require protection from the elements. Otherwise, the open cargo trailers will work for you.

Do not forget about business expansion

You shouldn’t limit your buying criteria to your existing business model. The business can grow after a few months, or even years. You might need to purchase another trailer in such an instance. Consider buying a trailer with extra space from the start. Although it may be costly, you will pay back in the long-term.


You should consider the following points when planning your budget. You will be able to choose the right size trailer for your purposes if you know exactly what you are doing with it. Consider the growth of your company and consider a larger budget. Hobbyists should have a smaller trailer.

That’s it! Your initial plan is complete. You are now ready to buy the product. Here are the next points you should consider.

The construction type

First, inspect the trailer from the inside. As the trailer’s main load bearer, the frame is of paramount importance. Cargo trailers can generally be constructed of aluminum or steel. They can be seen in L-shaped, C channel beams, I beams and tubular. The ones with the largest chunk of metal are known to be the strongest. It is also important to design the beams. Cross beams capable of supporting the most heavy loads are the best.

The number of axles

A cargo trailer with one axle is sufficient for smaller loads. These are great for small businesses, as you can see. This trailer is a great option for small businesses as it comes with a single axle. You don’t have to invest in heavy-duty trailers, which can save you a lot of money.

These single-axle trailers are best if your load is less than 3000 pounds. For heavier loads, multiple axle trailers are required. These trailers are heavy-duty and will evenly distribute the load. It will also provide much-needed shock absorption as well as good control while driving on the roads.

The size

We discussed earlier how your business’s purpose determines the size and shape of the trailer. It is also important to consider the possibility of expanding your business. Eight and a quarter feet wide and sixteen foot deep are the best options. We recommend a multi-axle cargo trailer to accommodate future growth.

The doors

You should decide the type of cargo trailer doors based on what you are hauling. Ramp doors work best for heavy loads like 4×4 vehicles and snowmobiles. Barn doors are more beneficial if the cargo trailer is used to transport inventory that is less heavy.


These trailers are not for business owners. Transport professionals need to inspect the trailer’s key features. The thickness of the trailer’s outer skin can make all the difference. Thicker skins will provide the greatest protection against burglars and natural elements. Another important aspect to consider is the roof.

Trailers can have either a flat or rounded roof. Flat trailers have a lower interior ceiling, while rounded ones have a higher one. If you’re dealing with perishable goods, air conditioning is also essential. You can also convert the trailer into a workstation, even if it isn’t on the road.

The size of the trailer should be matched by tiers. You can choose the type of cargo that you want to transport if you’re buying a used trailer. Most trailer tires are strong. However, depending on the driving conditions and frequency of operation, it may be necessary to purchase specialized tires.

Choose utility over killer looks

You can customize the cargo trailer to your specifications. Don’t let trailer appearances influence your decision to buy. Your business’ success is dependent on its durability. Your ultimate goal is to have a trailer that provides maximum protection from heat, rain, storms and snow.

The bottom line

You should have all the information you need to find the right trailer for you. Your business will explode if you have the right enclosed cargo trailer.
