A brand-new development was made with a joint effort of Additive Composite and Add:North, both Sweden-based companies. The Addbor N25 filament is expected to designate the beginning of a new era. The new composite has radiation shielding capabilities, which means it can be used for 3D-printing of radiation protection means. It is compounded with co-polyamide matrix as a base polymer filled with boron carbide. The filament composition provides for a higher degree of chemical and heat protection levels. 

The material is expected to be applied in nuclear industry, research labs and other facilities that suggest radiation exposure. Its main anticipated area of implementation is production of radiation-shielding equipment that’s free from toxic heavy metals, such as cadmium.

 “Additive manufacturing is changing how many products are being designed and produced. We believe that Addbor N25 contributes to this development and helps both industry and large research facilities to replace toxic materials that could eventually contaminate the environment,” says Adam Engberg, CEO of Additive Composite

Boron carbide accounts for 25% of the compound’s total weight, and the filament density is expected to be 1.33 g/cm3. The recommended settings for stable printing are the following: nozzle temperature of 250-270ºС (480-520ºF) and bed temperature ranging from 60 to 100ºС (140-210ºF). 3D-printing is recommended to be carried out using hard ruby nozzles developed by Olsson Ruby or sapphire nozzles produced by SAPPHIRUS due to filament’s abrasivity and hardness. The use of above-mentioned nozzles will ensure that printing quality stays high and prevent nozzle sprayers from wearing out too quickly. The manufacturer suggests using nozzles with the diameter of at least 0.4 mm (0.016in). The filament is promised to feature excellent layer bonding, moderate flexibility, low shrinkage and good chemical resistance. Furthermore, the tensile strength at break is 58 MPa and flexural modulus is 1425-3650 MPa. Addbor N25 can easily handle continuous utilization at 100-110ºС (210-230ºF).

The cost of a 1.6 lb (750g) filament spool is 9 500 SEK (980 USD). Taking a different perspective, that’s a medium cost for a used car. The available filament diameters are 0.07 inches (1.75 mm) and 0.1 inches (2.85 mm). The product page is available on Additive Composites’ official website.

Since the existence of 3D Printing, also called additive manufacturing, its presence has become more and more vital in the industry. It is the technique of putting together a 3-dimensional object from a computer-generated 3D model wherein many computer-controlled methods are included. Amongst the most usually perceived is the layer-by-layer joining of elements, named as solidification. Needless to say, with its emerging use, it offers great benefits to users. But apart from benefits, it has a few limitations as well. It holds several critical issues that sometimes users find hard to resolve. It may be due to improper functioning of printer cartridges or due to something else. But to ensure professional quality printing results, addressing issues becomes a necessity. 

If you are also interested in using 3D printing technology in your printing business, then this article is just for you! Here, we will put a deep light on some of the common issues that users can face using this technique and feel stuck in a printing job. Moreover, we will also give accurate solutions to address and fix the issues hassle-free. 

So, don’t go anywhere! Be with us for the next few minutes and enjoy reading!

5 Common 3D Printing Issue Are As Given Below

  • String Issue 

The ones who had used a quick-drying adhesive material like glue can well interpret how irritating stringing issues can be. This issue in 3D printing happens when excess fluid stuff gets out of the nozzle, leaving “strings” in its trace as it transfers from one section to another. Aforementioned intends to produce an object with ugly lines/strings that seem like gossamers all over it. 

Addressing this problem is very simple. The professional technician can switch on the machine’s retraction function to retract back the plastic and filament material from the nozzle before transferring from one printing area to another. That effectively stops profusion drips and helps you have smooth printing results. 

  • Warping Issues

It is to be said that 3D printed objects are of far more solid quality than conventionally produced ones. Nevertheless, like any other method, 3D printing is also sensitive to common device errors. one of those errors, a very common error or issue that has been noticed and troubleshot by many users, is “warping”. Wrapping issues generally occur when the base of the printed object begins to bend, tilt, fold, and it does not settle flat on the printing surface. This issue will not just tilt the printing object, but also lead to horizontal cracks that further ruins the quality printing job. 

It’s quite obvious when the printing machine is not being able to print perfectly and on appropriate spots, then it destroys the printing tasks operating on a wider scale. Technical persons/engineers can address this issue easily and resolve it with the best ways possible too. By using a  heated print platform, engineers set the temperature just below the plastic’s melting point and start resolving this issue. 

  • Clogged or Jammed Extruder

You may have heard that 3D printers extrude several kilograms of plastic in its entire life. To make things worse and more complicated, this plastic outlets the extruder sometimes via a small hole and starts creating printing issues. Unavoidably, there comes a time when everything starts going wrong in the printing process and the extruder stops pushing plastic through its nozzle. The simple & straightforward reason behind it is jams & clogs!! The jams or clogs occur as something stuck in the nozzle, which blocks the plastic from completely extruding.

It may seem quite daunting to resolve this issue. But by implementing the best ways or the troubleshooting steps, anyone can resolve it easily. 

Here is a list of some of the common troubleshooting steps that you can implement to get rid of this issue. 

  • Again load the filament carefully
  • Cleanse the nozzle thoroughly
  • Manually shift the filament into the extruder

Implementing these easy and simple steps, you can resolve this 3d printing issue. 

  • Weak Infill Problem

Undoubtedly, the infill in your 3D printed object plays a vital role in the durability of the design. The infill is accountable for joining the outer shells of your 3D print, and strengthening the upper surfaces, which will be printed on top of the infill. But the issue that can trouble users is infill gets weak or gluey. But remember one thing in mind, nothing is permanent and this issue can also be resolved easily.

All you need to make a few adjustments in your software settings so you can add an added strength to this section of your print and determine the problem. Here we have summed up common solutions to this problem that you can implement. Have a look! 

  • You can reduce the print speed
  • In addition to it, you can also try alternate infill patterns
  • You can expand the infill width of the extrusion 

Employing these steps cum ways, you can troubleshoot this issue and have a happy and hassle-free printing! 

  • Issues Related To Dimensional Accuracy

Last but not least! Here’s another important issue that users can face in 3d printing is related to dimensional accuracy. No doubt, the dimensional accuracy is extremely significant in 3d printing if you are producing a bulk of devices or components that want to be accurately fit together. And many factors can affect dimensional accuracy and lead to bigger manufacturing issues. 

You can have dimensional accuracy errors in under extrusion & over-extrusion, thermal contraction measurements, filament quality & quality analysis, and the nozzle alignment. But using tools & techniques, you can simplify and resolve this issue in the one-go. 

  • Start printing a model with 50-100 layers and measuring the top 20 layers.
  • Begin analyzing the difference between perimeters & holes in the top surfaces. 
  • Offsetting the edges of your print to understand the dimensional errors & differences.
  • Adjusting the required settings. 
  • Double-click on your 3D model to simplify the interface and set the scale to 100.5% so you can reduce dimensional errors. 

These tips will surely help you fix dimensional issues.
