Additive manufacturing, or what most people know as 3D printing, is a complex process of producing 3D solid objects using digital files.

To generate a 3D object, you must utilize a 3D printer that creates the object through an additive process. In this additive process, the 3D object is usually made via laying down multiple successive layers of 3D printing components until the 3D object emerges. Every layer in a 3D object can be viewed as a thin cross-section of a 3D object.

The opposite of three-dimensional printing is known as subtractive manufacturing, a process of producing components via hollowing out or cutting out pieces of plastic or metal using milling machines.

Three-dimensional printing lets you generate complex 3D shapes using relatively fewer materials as compared to traditional manufacturing processes.

How does Three Dimensional Printing Work

Full PCB Manufacturing

3D printing starts with simple 3D models. You can choose to generate this model yourself to get that custom feel, or you can still gain them from the internet via the many 3D libraries that exist.

3D Software

There are so many software tools in the market today that range from open-source to industrial-grade. Using this Software, you can quickly generate a custom 3D model to use with your 3D printer.

If you are a beginner, you should try starting with free-to-use 3D printing software. Most of these software programs are efficient and easy to use, making them great for beginners. Moreover, some of these software programs even run on browsers. Therefore you don’t have to install them on your computer.

Most software programs provide beginners with lessons on how to use the Software. Moreover, they also feature a built-in functionality that lets you export your 3D models as printable files, for example .OBJ and .STL.

After you have your 3D file ready, the next phase involves preparing the model for your three-dimensional printer via a process known as slicing.


Generally, slicing means slicing a three-dimensional model into various layers which might reach hundreds or even thousands. To carry out the slicing process, you must utilize a software program.

After completing the slicing process, your 3D model file is ready for the 3D printer. You then have to feed this file to the 3D printer via the printers input preference, which might be:

  • WiFi
  • SD
  • USB

At this point, you can now leave the 3D printer to generate your 3D model via the layering process.

Three-Dimensional Printing Industry

The adoption of three-dimensional printing has hit critical mass. Therefore, those yet to include 3D printing in their production process are missing out on a lot. Moreover, those using this tech gain a competitive advantage via speedier production rates with minimal material loss.

Earlier on, three-dimensional printing only fit in one-off production and prototyping. However, as of the 21st century, this technology is now transforming into production tech. Therefore, adopting this technology is the right move.

However, in terms of technology, there are two significant categories of 3D printing tech:

  • FFF or Fused Filament Fabrication tech
  • SLA or Stereolithography tech

Moreover different printers contain different components for instance some printers have linear rails while others don’t.

Before you decide on the type of Flsun three-dimensional printer to go with, you must know the type of 3D printing technology you wish to use in your project.

FFF Technology

Fused Filament Fabrication is the most popular type of three-dimensional printing technology in the market today. Its popularity comes due to two reasons:

  • Ease of utilization
  • Lack of resilience when working with harsh chemicals

FFF utilizes thick string-like components that are known as filaments. The materials filament diameter is usually 2.85mm or 1.75mm. Moreover, filaments are generally thermoplastics that are delivered via spool.

The Fused Filament Fabrication process extrudes filaments via a nozzle. The 3D printer nozzle is typically placed in a motion system that moves the nozzle around a printing or building area during the 3D printing process. Melted filament, which ejects out of the 3D printer nozzles, settles on a printing plate, forming different layers according to the 3D model file. While on the printing plate, the molten filament cools and effectively solidifies, creating a single layer. As the nozzle ejects molten filament, the printing bed moves down a couple of millimeters per time fraction to begin a new layer. For a 3D printer to form a complete 3D model, this process has to iterate multiple times. Hence this process is known as additive production.

Advantages of FFF

Resin 3D Printer

FFF has so many advantages, which include the following:

  • First, FFF printer equipment is user-friendly. Therefore you can efficiently operate and maintain it without a lot of trouble.
  • FFF process and equipment tend to be less expensive when compared with other three-dimensional printing processes
  • The FFF printing process tends to be relatively clean. Moreover, this process does not include the utilization of harmful or harsh chemicals.
  • FFF printers tend to be pretty compact such that they can easily fit on tight spaces
  • The FFF printing process occurs in one station. Therefore you do not require more gadgets which adds to the budget.
  • You can utilize many materials for this printing process, all with different engineering properties. Therefore, you can select the printing material that fits our production process.


Even though FFF technology is efficient, it still has some drawbacks, which include:

  • Visibility of layer lines on the final products
  • Layer adhesion quality can significantly influence the part’s mechanical strength

Under this category of 3D printing technology, you can find a couple of Flsun 3D printers which are pretty reliable, durable, and efficient. These Printers include:

Flsun QQ-S 3D Printer and its Incredible Print Speed

Flsun QQ-S 3D printers are predecessors of the famous Flsun QQ 3D printer. However, even though this product is an upgrade of the QQ, it is still pretty affordable. Moreover, like similar delta printers, which are in the same category as the QQ-S, these printers have one general characteristic: a circular printing bed. Furthermore, these printer’s extruders are usually on top of the printing bed, suspended by three arms, forming a triangular placement configuration.

Generally, the QQ-S is designed for efficiency and impeccable printing speed. Their print speeds are unmatched under this category. However, these printers have a distinction in that their printing beds are static; they don’t move.

Moreover, the QQ-S 3D printer now features impeccable updates, which include lattice print beds, a thirty-two-bit motherboard, and titan extruders.

But what do these additional updates bring to the table:

Lattice Bed

The Lattice bed is an efficient high-strength and quality lattice composite coating platform that offer less warping and fast heating. Moreover, this platform also provides impeccable adhesion during 3D printing, which accounts for easier ejection of the 3D print once it is complete. All these features take us back to Anycubic Ultrabase. Moreover, the benefits of utilizing a high-technology glass print bed are clear. Using this component, you can release 3D prints as they cool off, eliminating the need for glue sticks, hairspray, scarpers, and the awful mess that emerges from using these items.

The lattice heated bed temperature hit around one hundred degrees Celcius in five minutes or less, which allows for the utilization of the most common 3D printing filament without any issues.

Since the QQ-S is among the Delta series, its lattice bed is static. Therefore you only need to auto-level it once, which makes this 3D printer great for beginners.

Titan Extruder

The Titan extruder is another update that you will find on the QQ-S. At first glance, you might confuse the titan extruder with the popular E3D Titan Extruder. However, this extruder allows for more powerful extrusion and smoother and more efficient feeding of filaments. By default, the titan extruder comes bearing a 0.4-millimeter extrusion nozzle. However, this nozzle can also handle 0.3-millimeter and 0.2-millimeter nozzles which allows for a much finer print.

Bearing a max temp of around two hundred and seventy degrees celsius, the QQ-S can easily handle common 3D printing filaments, which include:

  • Wood
  • PVA
  • PLA
  • ABS

Moreover, it can also handle flexible and HIP components.

32-bit Motherboard

Every 3D printer contains a controller board that acts as the brains of the printer. The controller board orchestrates significant components such as sensors, motors, heater beds, and extruders. Therefore, the more powerful the motherboard is the more efficient the printing process will be, and vice versa.

While the predecessor of the QQ-S (the QQ) 3D printer runs on an eight-bit motherboard, the QQ-S runs on a 32-bit controller board. Moreover, the QQ 3D printer utilizes an Arduino Mega 2560, but the QQ-S runs on a different model known as a Robin Mini Board, which allows it to handle fast 3D printing with much ease and stability. Moreover, the board has a WiFi connection and a touchscreen for a better user experience. Furthermore, this motherboard also bears feature that let it:

  • Resume printing from breakpoint
  • Save print info in case the printer losses power
  • Detect when the filament is about to be exhausted
  • Turn off the 3D printer automatically once it is done printing
  • automatic connectivity

In general, this motherboard is pretty efficient and it helps in terms of achieving higher printing speeds.

SLA Technology

SLA, or stereolithography technology, is a type of 3D printing tech that utilizes liquid resin as raw material and ultraviolet light to generate 3D products. Before the 3D printing process, you must pour resin inside the glass bed container.

During the printing process, the building platform is submerged inside the container or resin tank. A DLP or UV light projector then shines ultraviolet light on the prior put resin to harden it selectively into horizontal layers according to the design specifications. After the selective hardening process, the printing platform is raised out of the resin container, which ultimately allows the uncured parts to level out effectively. To generate a 3D print, the 3D printer has to iterate through this process multiple times.

Advantage of SLA

SLA technology has multiple advantages, which include:

  • Easy-to-use and relatively compact gadgets
  • Moreover, these printers broaden the scope of 3D printing since you can effectively develop many 3D prints.
  • Compared with FFF, SLA produces 3D sections with smoother surface finishes. Moreover, this technology produces more detailed 3D prints.

Disadvantages of SLA

Even though SLA is efficient, it still bears some significant drawbacks, which include:

  • Consumables are not safe to handle with your bare hands. You have to wear gloves. Moreover, they are highly flammable and bear an unpleasant smell.
  • After the print process is complete, the 3D prints require further curing for them to heal effectively, unlike FFF 3D prints.
  • SLA 3D printing materials are sticky. Therefore, they can easily contaminate your workplace. If you don’t let the models heal appropriately.
  • When utilizing an SLA printer, you almost always have to utilize support structures.
  • SLA 3D printers have s build volume that is relatively small compared to FFF printers.
