How To Use A Large 3D  Printer

To start using a large 3D printer, you must first  download the software needed to operate it. Then, you must set up the machine  itself. After that, you can begin designing whatever you want. There are many  programs available online that let you design anything from simple models to  complex ones. Some of the most popular programs include Autodesk 123D Design,  Google Sketchup, and Solidworks. Each program has its own advantages and  disadvantages. However, whichever program you decide to use, remember that  you'll need to learn how to use it. Otherwise, you won't be able to use the  3D printer effectively.

Using a large 3D printer offers  several benefits. First of all, it saves money. Since you no longer need to  pay for materials, you can cut costs significantly. Second, it saves time.  Because you don't need to wait around for the material to dry, you can 

The Importance of Purchasing a Quality Large 3D Printer 

There are many different types of printers available  today. Some are designed to print small objects while others are capable of  printing larger models. There are several factors that determine which type  of printer you should invest in. Here we will discuss these factors and give  you tips on how to select the right printer for your  needs.

Size Matters

One of the most  important aspects of selecting a printer is size. Most printers are either  desktop or portable. Desktop printers are typically built into desks and  require electricity to operate. Portable printers are smaller and lighter  weight and can be moved around easily. However, they cannot produce very  detailed prints.

Print Speed

Another  factor to consider is speed. How fast does the printer print? Does it take  hours to complete a project? Do you plan on making multiple copies of the  same object? All of these questions must be considered when determining the  speed of the printer.

Material  Type

Most printers are able to create plastic parts.  Others can create metal parts. For example, laser cutters can cut metals and  plastics. Other machines can create ceramic pieces. Each material has its own  advantages and disadvantages. Plastic parts are generally cheaper and easier  to mold. Metal parts are stronger and durable. Ceramic parts are lightweight  and easy to carve. Choosing the correct material depends on your specific  application.

Software

Some printers  include software programs that allow users to design their own products.  Software packages are helpful for creating complex designs. However, there  are limitations to using software alone. Many times, the software requires  additional hardware components to function correctly. Therefore, it is  recommended that you purchase a printer that includes both software and hardware.

Accessories

Many  printers include accessories such as ink cartridges, paper trays, and storage  containers. Accessories are useful for storing materials during breaks or  when traveling. Make sure that the accessories included with the printer meet  your needs.

In conclusion, there are numerous  considerations to think about when deciding which printer to 

Features To Look For When Buying A Large 3D  Printer

1) Size Matters 

The size of the print bed matters most when  purchasing a 3D printer. Larger printers allow you to create larger objects.  Smaller printers require you to be closer to the build plate. Most  manufacturers recommend using a minimum of 1/2 inch (12mm) between the nozzle  and the build plate. However, there are exceptions where smaller distances  are acceptable. Some manufacturers claim that nozzles can be placed within  0.5 inches (13mm).

2) Build Plate Material  Matters

Most 3D printers today use aluminum  plates. Aluminum has many advantages including being lightweight and easy to  cut. But, aluminum does have its disadvantages. Aluminium tends to warp and  bend which causes problems during printing. Many users report warping issues  with their prints. Other materials include steel, plastic, glass, and  ceramic. Each material offers different benefits and drawbacks. Steel is  heavy and durable. Plastic is flexible and cheap. Glass is strong and scratch  resistant. Ceramic is hard and heat  resistant.

3) Print Bed Type Matters 

There are two types of beds available; heated  and unheated. Heated beds are preferred since they eliminate the risk of  damaging the object being printed. Unheated beds are cheaper and easier to  maintain. However, they cannot produce high quality prints due to lack of  temperature control. There are also hybrid models that combine both heated  and unheated beds. Hybrid models are generally considered to be the best  option.

4) Support Structure Matters 

Some 3D printers have built-in support  structures while others require additional supports. Supports are needed to  ensure stability and accuracy. Without supports, the printer could collapse  causing serious damage to itself and the object being printed. Supports can  range from simple cardboard boxes to complex metal frames. Supports are  typically required for larger builds.

5)  Speed Matters

Speed is another factor to  consider when selecting a 3D printer. Faster speeds result in higher  resolution prints. Higher resolutions are desirable since they increase  detail and reduce file sizes. Unfortunately, faster speeds also decrease  print times. Printing speed varies depending on the type of filament used.  Filament extrusion rates vary from manufacturer to manufacturer. Some  filaments take longer to melt than others. Some filaments contain additives  that slow down melting. Others are designed specifically for fast  printing.

Different Types  of Large 3D Printers

There are many different kinds of  printers available today. Some are small enough to be carried around while  others are big enough to fill a room. There are both consumer grade and  industrial grade machines. Each type has its own advantages and  disadvantages. Here we will discuss three popular models of large scale 3D  printing devices.

FDM (Fused Deposition Modeling)  Printer

The fused deposition modeling machine uses plastic  filament to build objects layer by layer. The process begins with melting the  plastic into a liquid state. Then the heated nozzle deposits the melted  material onto the print bed where it cools and hardens. After each layer is  deposited, the object moves forward slightly and another layer is added. Once  complete, the printed part is removed from the print bed and finished using a  heat gun to melt away the support structure.

SLA  (Stereolithography) Printer

This method builds parts by  laying down thin layers of resin which solidify together. As each layer is  laid down, the previous layer becomes hardened. The final product is created  by building up multiple layers of resin. SLA printers typically produce  smoother prints than FDM printers due to the way the layers are built.  However, SLA printers require a lot of post processing to remove supports and  finish the part.

SLS (Selective Laser  Sintering)

In selective laser sintering, a powder metal  mixture is spread across a flat plate. An intense beam of light scans across  the top of the plate causing the particles to fuse together. The completed  part is then lifted off the plate and placed in a furnace to burn away the  excess material. The result is a very dense part that requires little  finishing.
