Ultimate 3D Printing Materials Guide

What Is 3D printing?

3D printing, also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object. The 3D printing process starts with an electronic file that is created by either scanning or modeling software. The electronic file consists of thin horizontal cross-sections called layers that are saved in. STL format files.

The machine reads these files and begins building the object using its stock material (i.e., plastic filament) one layer at a time, following the sequence defined within the electronic file. This process allows for easy customization and replication of objects which would otherwise be impossible or prohibitively expensive to create using traditional manufacturing.

3D printing material

While the process is digital, 3D printing is not simply making a virtual copy and producing it as a physical object. The machine prints each layer by squeezing successive rows of material onto the previous row until all layers have been added and the object has reached its desired height/thickness.

The printer then moves up or down one layer thickness (the Z-axis) and prints another layer on top of this first one. It continues doing so until all of the layers have been stacked into place, and it has produced an actual physical item that can be handled and used like any other manufactured product. Not only does this make 3D printing an incredible tool for creation, but it also allows the process to be more environmentally friendly by reducing material waste.

Unforeseen Advantages of 3D Printing

Rapid prototyping technology has undoubtedly opened new doors in the industry. Are you considering getting an additive manufacturing machine for your business? Or are you looking to use it for personal or academic purposes? However, before you do so, here are the advantages of 3D printing you should know about.

Additive Manufacturing Technology Can Reduce Costs

While 3D printing technology can help reduce costs, it is essential to note that any 3D printed part or product comes at a price. However, many industries and businesses admit that they stand to gain more than they lose by using this technology.

While additive manufacturing may be more expensive than subtractive manufacturing (such as CNC machining) in some cases, it is often much cheaper when you consider the entire lifespan of the part produced. Other industries such as the aerospace and automotive industry consider other factors that make up for their higher initial investment in these machines.

Enables the Production of Complex Shapes & Designs

It is very difficult and expensive to produce complex shapes and designs with traditional manufacturing methods like CNC machining. This is because such shapes require multiple machining setups to get the final shape. However, with 3D printing technology, you can easily create such complex parts without any hassle. Moreover, this technology does not have any restrictions on the size of components; you can print huge-sized objects using this additive manufacturing process, which further lowers your production costs.

3d Printing Has Low Environmental Impact

Environmental awareness has become a priority for many businesses and manufacturers worldwide, and metal additive manufacturing machines are no different in this regard. Many 3D printers today operate with minimal noise emissions and low energy consumption, making them more environmentally friendly than other traditional manufacturing methods like CNC machining.

3D Printing Technology Helps in Saving Time & Labor Costs

Not all industries have the luxury of human labor, but those who do can benefit from using these additive manufacturing machines as they help in saving time and labor costs. For instance, using a 3D printer for prototyping allows you to build multiple prototypes quickly, which reduces your production time and cost significantly.

Moreover, suppose you are a designer or developer working on a project with tight deadlines. In that case, additive manufacturing technology can be a great boon for you. It can save significant amounts of time that would otherwise be wasted on designing a prototype first and then testing it later via traditional methods like CNC machining or mold making.

Helps in Creating Aesthetically Pleasing Components

If you are producing commercial products, then your product must look appealing to your target customer base. 3D printing technology helps in producing aesthetically pleasing components without any additional effort on your part. Once you have created the design for the component using computer-aided software or modeling software, simply upload it to a 3D printer and let the additive manufacturing machine do its job by producing beautifully designed objects one layer at a time.

Can Be Used to Produce Functional Components

Additive manufacturing machines can not only be used for prototyping but can also be used to produce functional components as well. For instance, if you need custom gears and pulleys for your machine, it makes sense to use 3D printing technology as you can easily create such components without any hassle. Moreover, these machines are great for making custom components that require high accuracy and precision.

Low Risk of Prototypes Being Rejected

Once a prototype is ready, the next important step in the product development process is approval from the concerned authorities or end-users before mass production begins. However, this often leads to issues as many prototypes fail due to flaws present in their design that may not be visible during prototyping itself.

The problem gets exacerbated with traditional manufacturing methods like CNC machining as they require expensive molds and tooling to begin mass-production of a good. However, if you are using 3D printing technology for prototyping, there is much less chance of your product being rejected. The number of prototypes that can be printed is almost unlimited at a relatively low cost?

No Waste of Raw Material

One of the biggest advantages of additive manufacturing machines compared to other conventional methods like CNC machining is that no material goes to waste during production. Even though 3d printers build objects layer by layer, they make use of all the raw materials used in their printing process, unlike traditional manufacturing methods, which leave behind scraps and chunks after completing the required piece. Moreover, this added advantage dramatically reduces your wastage costs, making it more efficient than other manufacturing technologies currently available in the market.

Can Be Used to Produce Highly Complex Pieces

3D printing technology is excellent for producing highly complex and intricate pieces. It offers the ability to print some of the most complicated shapes that are almost impossible to make using other conventional manufacturing methods like CNC machining. This results in cheaper and more efficient products which can be customized according to your needs as per available resources.

Moreover, suppose you need custom molds or tools for prototyping. In that case, additive manufacturing machines can help you save a lot of money and time by requiring only a few prototypes before moving on to mass production.

Allows for Mass Customization

One of the biggest reasons why 3d printers have become so popular among business owners across various industrial segments is their ability to produce custom components for their machines easily. You can create custom molds and tools that do not require any additional costs or expenses by using additive manufacturing technology. Moreover, if you are looking for customized pieces for your manufactured units, these machines can help you design them without breaking the bank.

Types of 3D Printing

The 3D process has been around for centuries but has recently become increasingly popular as 3D printers have dropped in price and software to design models has become more widely available. The main types of 3D printing are plastic, composite, and metal 3D printing.

Plastic 3D Printing

Plastic 3D printing uses a gradual layering approach to create parts layer by layer to create a finished product. It can be used with almost any type of thermoplastic material, including:

  • * ABS (the same kind of plastic used to make Legos)
  • * PC
  • * PEEK
  • * Nylon
  • * PLA (a biodegradable thermoplastic made from corn starch that is used for prototyping and other purposes).

The plastic 3d printers can vary in their accuracy, speed, material cost, and size depending on the type of printer.

Composite 3D printing

Also known as laminated object manufacturing, it uses thin layers of high-strength materials like fiberglass, Kevlar, or carbon fiber which are cut from a roll of material and laid down on top of each other. This process is similar to the plastic 3d printing technique known as FDM, except that it uses sheets of solid material instead of thermoplastic. In addition to these strong materials can also be used with more conventional sheet materials like paper, textiles, and plastics.

Metal 3D Printing

Metal 3D Printing (also known as 4D printing) is a type of 3D printing that creates products that can morph into different shapes. Instead of using traditional thermoplastic or sheet material, the 0’s and 1’s in a computer program are used to print an object that is able to fold into itself or be tied into knots. This allows for more complex objects than what would otherwise be possible through traditional manufacturing without needing support systems. It also means that designers can create things like shoes with rubber soles that stay curved when they’re not being worn instead of becoming flat, which has been problematic in the past due to the lack of flexibility in most shoe soles.

An Overview of Popular 3D Printing Materials

When it comes to 3D printing, the materials used are just as important to what you’re printing as well as how you print it. Here, we will go over a few of the flexible 3D printing material, most popular and best material for 3D printing and why they might be chosen for a certain project.

  • * ABS (Acrylonitrile Butadiene Styrene) is a petroleum-based thermoplastic that can be dyed with ABS dyes or pigments. It offers good strength, flexibility, and toughness. It has great chemical impact, fatigue resistance and is easily painted.
  • * PLA (Polylactic Acid) is made from renewable resources like corn starch or sugarcane. PLA biodegrades quickly in commercial composting conditions achieving disposal without adding toxic chemicals or plastics to our landfills or environment.
  • * ASA (Acrylonitrile Styrene Acrylate copolymer) offers high tensile strength and stiffness, unlike its counterpart ABS, but lower than PETG. It is not as durable or flexible as ABS but has much better chemical resistance than ABS, especially acids.
  • * PET (Polyethylene Terephthalate) is easy to print and offers good durability and impact resistance, higher than PLA. But it doesn’t provide the toughness of ABS, which makes it brittle at points that need strength; this means that printed parts may fail prematurely in high-stress areas under heavy loads before an ABS printed part fails.
  • * PETG (Polyethylene terephthalate glycol-modified) is much like PET, except it has a lower coefficient of friction (which means less resistance when sliding parts against each other).
  • * Polycarbonate (PC) has much higher temperature resistance than PLA or other materials, which means it can withstand greater stress. High-strength Polycarbonate formulations are commonly used in bulletproof glass. It is more rigid and offers better impact resistance than ABS.
  • * Polypropylene (PP) has good chemical resistance but only medium strength properties. The melting point of PP is around 175C to 180C at the extrusion temperature of 250C to 260 C
  • * Nylon offers high strength properties to weight ratio, rigidity, dimensional stability, toughness for impact loads, and long-term corrosion protection with all metals. Printing nylon requires being above room temperature because it doesn’t melt below the glass transition temperature (~154 ℃ ). If this temperature is not reached, the material will tend to adhere to extruder parts, and nylon stringing can occur. This phenomenon limits its use as a printing material.
  • * Resins are polymers that solidify on exposure to specific stimuli such as heat or UV light. These materials offer impressive properties, including durability, strength, detail resolution, color depth, and the ability to post-process parts with paint, varnish, a clear coat finish, etc.


With so many advantages associated with 3D printing technology over traditional CNC machining methods, it is no surprise that manufacturers across various industrial lines have started leveraging this fantastic technology in their production process. From designing highly complex parts to mass customization, this technology has changed the way products are being developed and manufactured today. With time, we expect its use to become even more widespread as demand for innovative and efficient means of production increases.
