3D Printers: Ways to Increase Print Speed

Several businesses use 3D printing, a form of additive production, for prototyping or manufacturing components. It is a computer-based process that lays down layer after layer of a product till it is full. The procedure uses metal or plastics and begins with a 3D digital version of the last object. Awaiting a challenging print resembles enjoying grass growth. Below are some strategies for raising the print speed.

3D Printers: Increase Speed

3D Print at Lightning Speed

One usual way to enhance print speed is by modifying the slicer’s rate. This makes it likely to slow or increase the print head, improving the look. And on well-designed items, the print rate can be raised.

Use Thicker Layers and Larger Nozzle

Thicker layers considerably lower print times. If precision is not the priority, then think about printing with the highest layer density and a sizable nozzle. The optimum layer needs to be 75% of the nozzle size. Consequently, a 0.8-mm nozzle can construct 0.6-mm layers.

You will observe the layers of the item coming to be thinner. This enhances the final object’s firmness. Yet thicker layers imply losing the product’s great information. It is additionally vital to obtain the best nozzle for the task available.

Adjust Infill Thickness and Wall Thickness

Solid prints are done using thicker and stronger outliners, filled with a honeycomb framework. If you stop working on using this form, the 3D image will undoubtedly take a long time. In case you utilize an infill, there are various options to boost the printing rate. For example, you can decrease infill even more. Nevertheless, remember that the proportion in between the infill and wall density will certainly be kept. This protects against versions from breaking and even collapsing over time.

Acceleration and Jerk Settings

Jerk setups impact precisely how quick the print head steps from a still spot. To get the most effective top-quality print, make sure the image in advance relocates easily rather than swiftly. This is the speed that the printer would instantly jump to before increasing.

Acceleration settings of 3D printers impact just how swiftly the print head reaches its full throttle. Thus, having a reduced velocity suggests the printer will not reach its full throttle with smaller objects. Enhancing the jerk value minimizes printing times, yet it could cause mechanical stress and a feasible reduction in the top quality of print due to vibrations. To obtain the best quality, stay clear of affecting the product’s quality, individuals require to strike balance and discover the best jerk setup, which would likely be a mid-level setup.

Restriction the Variety of Assistances

The more assistance a product needed by a consequence, the longer it will certainly take to publish. Consequently, it is best to print items that do not require any assistance. Several methods can assist in creating things that do not need support. At present, most designs do not require assistance. Removing them is just among the most efficient means of 3D printing without the need to sacrifice toughness or quality.

Ultimately, do not expect to produce perfect items the very first few times. Care for your filament. Also, when with quality issues, review the settings and implement the required modifications slowly. Bear in mind; every print is a finding out the opportunity.

What is 3D Printing?

3D printing, otherwise known as additive manufacturing technique, is a qualified production method that allows you to make a solid object out of a digital file in 3-dimensional form. 

The one thing that can’t be taken away from the creation of 3D printed objects is the involvement of additive processes. It is always at the core of 3-dimensional printing. The object here is created by successive layering of the material’s film until such time that the target object you want to produce is taking form and shape. These layers are represented by the cross-section of the object that is sliced thinly. 

Additive manufacturing or 3-dimensional printing is the absolute opposite of subtractive manufacturing, which is all about hollowing out or cutting out a piece of plastic or metal with the help of, say, a milling machine.  

Unlike traditional manufacturing methods that we know and are most familiar with, 3-dimensional printing allows for the production of custom intricate shapes and forms using fewer materials.  

Examples of 3D Printing 

Encompassing a wide range of materials and technologies, many industries today are taking advantage of this innovative production technique to help them advance their market lead. We must look at this as a gathering of various industries characterized by the use of a handful of different applications. 

We have seen how the use and practical applications of additive manufacturing has grown in the last decade. Here are some of the product lines this technology is currently used in: 

  • Consumer goods (eyewear, footwear, design, furniture)
  • Industrial products (prototypes, functional end-use parts, manufacturing tools)
  • Prosthetics
  • Dental products
  • Architectural scale models 
  • maquettes
  • Fossil reconstruction
  • Ancient artifacts replication
  • Evidence reconstruction for use in forensic pathology
  • Props for film industry use

What Type of Ink Do We Use for 3D Printing? 

3D printing design

Whenever the topic of discussion is centered on plastics, we usually pertain to “plastics” in general. Anyone who considers himself a diligent recycler knows that we have various types of plastic materials in use today. Every single one of them is distinct from each other, both in their chemical and physical aspects.

This makes no surprise why 3D printer machines use thermoplastics since they come with a high level of versatility. This type of plastic will meltdown when heated at a certain temperature. But they will solidify to a custom shape when you cool them back down. The additive manufacturing industry knows this plastic by the name of ABS or acrylonitrile butadiene styrene. 

There is a high demand for this type of plastic in the additive manufacturing space because it is a composite of tough and hard plastic (acrylonitrile) that are melded together with synthetic rubber (butadiene styrene). This is what makes it perfect ink for use in 3-dimensional printing. 

At room temperature, the ABS-type of plastic takes on a solid form but will melt when the temperature is a little over 100°C (220°F). This temperature is cool enough to make the plastic melt while inside the printer without the need to produce too much intensive heat. But it is hot enough for printed 3-dimensional models not to melt when exposed under the sun. 

The ABS-type of plastic can be sanded if it is set already. After which, it can be painted on once smooth. Another distinct property of ABS plastic is that, in their raw form, they come in whitish-yellow color. But pigments can be added if your 3D printing project calls for a final product in a specific color. 

What About 3D Printing Services for Your Replacement Teeth?

The latest innovation we have about 3D printing services has something to do about the way we usually think about dental visits. 

Did you know that the work of a group of Dutch researchers from the University of Groningen made it possible to 3D print human teeth? 

The original plan they had is to just come up with an antimicrobial plastic capable of exterminating bacteria on contact. Such bacteria cause the outset of plaque on teeth which eventually will lead to no less than tooth decay. 

3D printing servicesHave you ever given it a thought that one day you will be able to finally give yourself the gift of pearly white but sans the accumulation of bacteria? This unseen enemy is behind every dental concern we know? If the prospect of having a 3D printed tooth inside your mouth is not ringing a bell of interest to you, is it any worse than when you have to constantly deal with toothache because of tooth decay?  

What the Dutch researchers found out is that the key component in designing a bacteria-fighting tooth lies in what they need to put right inside the 3D printing machine. For this, they embedded quaternary ammonium salts with antibacterial properties right inside dental resin polymers. Once inside a 3D printer, the power of ultraviolet light can be harnessed to harden it and use the material to 3D print replacement teeth.  

To test out the antibacterial properties of the tooth inside a laboratory environment, they made use of human saliva to coat the material. This allows it to be exposed to the bacterium that induces tooth decay. The results were astounding as expected because the antibacterial tooth exterminated more than 99% of all present bacteria. Another good thing about it is that there seemed to be no signs of it being detrimental to human cells. 


But this is not going to take away the fact that this 3D printing Australian scenario will still have a long way to go before it can become part of our reality. For instance, the Dutch innovation on 3D printing of human teeth has not yet reached clinical trials, and therefore no tests inside a human mouth have been made. Besides, these groups of Dutch researchers are still clueless as to how a 3D printed tooth would be reacting to brushing as well as when toothpaste is applied to it. 

Despite the presence of these seemingly insurmountable obstacles, there’s still room for optimism since the role of 3D printing inside the dentistry sphere is showing good signs of taking off anytime soon. Early this year, a prolific 3D printing group, Stratasys, were able to unveil their high-end dental 3D printing machine. They named their equipment as Object260 Dental Selection.

The said 3D prototype printing machine is more than powerful but ahead of its time because it can print out realistic-looking teeth, nerves, and gums. Therefore, making it easy and seamless to create life-like models for the exclusive use of dental specialists and professionals. 

The 3D printer machine is making use of the company’s polyjet dental materials. It makes it possible to produce gum-like colour and softness in the range that is closest to the natural shades of a tooth. 

In addition, it can also make the dental model nerve canals look so realistic giving dental practitioners good reason to make use of them in modeling complicated dental procedures.  

They are dental models that are not intended for use or application in clinical trials. This only goes to show the growing invaluable role of 3D printing services in the medical and dental spheres.

Right this very moment, there are still an awful lot of ongoing attempts and research, all done in an effort to “bio-print” human skin, bone, tissue, and even human internal organs. With respect to the report made by an independent research firm IDTechEx, they said that the dynamism of the medical and the dental market for 3D printers has nowhere else to go but grow in size in the coming years, to an estimated $867m industry come 2025.
