A Smart Way to Find Graphics from Free Sources All Over The World




It doesn’t matter what job you do that involved searching for graphics, you can quite easily end up regurgitating the same images repeatedly. Such is the nature of using free graphics, and rightly so because if you are just starting out, paying for a graphic designer can be an expensive task. Now the job of finding free graphics is limited because there are only a handful of sites out there that give you free downloads. What if we said there are ways you can get find a new crop of graphics?

Well, there is, and that is to download huge collections with 1,000s of graphics packs for all different niche areas. All you need to do is know where to look. There are several ways you can do this. First of all, get a VPN and start looking for foreign sites with free graphics available using foreign search terms for ‘free graphics’. Now you do not necessarily need the VPN, but it can help to give you localized results which are always helpful.

The second reason a VPN is useful is that it helps with your second strategy when hunting down free graphics packs. When we say ‘pack’, we are talking about huge zip files that are often 5, 10, 100 Gigabytes large collected by individuals that have worked in the graphic design or marketing industry for many years. They have kindly packaged together all the ‘paid images’ from well-known websites that charge a premium before you can get a copy of an image free of the site’s watermark or logo.

Where can you find these huge image packages?

You will need to use a torrentz software program, but before you do, make sure you protect your device. First of all, you need a decent anti-virus (AV) package, on top of this, you will want to make sure the AV software offers you a tool that gives you a ‘safe download’ area. That safe download area will not allow files to transfer to your computer until it has been deemed safe and free of malware and viruses.

Next, and also very important, you will need a VPN. VPNs are recommended whenever you connect to a torrentz network for several reasons. First and foremost, your ISP may not allow connections to torrent and end up shutting your connection down. Some ISPs will go as far as shutting down the ports that allow you to connect to torrent sites which they will not reverse, but a VPN connects to an external server with these ports open, so you can freely download torrents.

Lastly, as some of these graphics’ packages can be up to 100Gb in size, your connection will be open for quite some time inviting online intruders to test weaknesses in your connection. As your connection is always on, you will provide them with a target that is guaranteed to be turned on. Now the last thing you want is for someone to be able to open a gateway to your files.

We really hope that this guide has helped you and that it comes in useful. Getting the images is not exactly free because you need to pay a monthly VPN and AV fee, and quite possibly more monthly fees for a decent piece of torrent software, but the monthly costs you pay for these three components is far less than it would cost to gain access to such as a large number of images that as near as dammit allows you to build up an unlimited collections of graphics.

Ultrasound Can Help Improve Strength of 3D-Printed Metals




Scientists from the Royal Melbourne Institute of Technology (RMIT) discovered that ultrasonic exposure during 3D printing by Direct Laser Deposition allows obtaining high-strength metal products and even adjust the mechanical characteristics of individual sections.

The idea of ultrasonic exposure is borrowed to some extent from the powder metal industry: powder materials are often compacted before molding using ultrasonic vibrations. The Australian team conducted experiments on ultrasonic compaction right during 3D printing: the idea was not to compact the original powder but to change the microstructure of the resulting products.

The researchers point out that products produced by laser sintering of metal powders are notable for anisotropy — they consist of rather large, elongated crystals, which leads to a decrease in strength and increases the risk of cracking during printing. When the sintered material is exposed to ultrasonic waves, a stronger and denser microstructure is formed with smaller and equiaxed crystals. The scientists tested the idea on the directed energy deposition (DED) technology, where the powder is sprayed onto the substrate by a gas jet and selectively sintered with a laser emitter. The only difference was that a sonotrode and a 500-watt piezoelectric сonverter with a 20 kHz oscillation frequency were connected to the substrate.

The main material of the research was Ti-6Al-4V titanium alloy powder. During the experiments, the team managed to increase the creep limit and strength by 12%. For the sake of the experiment’s purity and proof of the general applicability of the method, the experiments were repeated with the heat-resistant nickel-chrome Inconel 625 alloy, with similar results. Interestingly enough, the method allows you to create products with a functionally-graded structure, that is, to adjust the strength characteristics of individual sections of printed products using selective ultrasonic exposure.

Although we used a titanium alloy and a nickel-based superalloy, we expect that the method can be applied to other commercial metals, such as stainless steels, aluminum alloys, and cobalt alloys,” – explains professor Ma Qian.“

Scientists believe that the method will be effective not only in conjunction with the technology of direct laser deposition of metal powders but also when working with rod-shaped materials. But there are also limitations: ultrasound can disrupt the distribution of powder in selective laser sintering or melt (DMLS and SLM), so for these methods, it is most likely that focused exposure is required directly on the sintered/fused areas.

Laser Sintering is not the only 3D printing technology that can show promise and deliver amazing results. If you’re opening a 3D printing-based business you will definitely want to check out the SLA technology. Whether you need it for your business or just for your hobby, a good SLA 3D printer will meet all your expectations. The Phrozen company is one of the biggest players in the current 3D printing market. The company offers multiple high-precision additive manufacturing devices, including the Phrozen Shuffle 4K 3D printer, one of the best solutions for a moderate price.

Best Eco-Friendly Packaging Ideas



Invest a lot more time and effort into finding the right value and quality for them. That being said, picking the right packaging and making sure that you take your time to do that right is not always going to be easy. This is why having custom mailing boxes or eco-friendly packaging can really help you a lot. Here are some tips regarding eco-friendly packaging that you can use today.


Single strip cardboard packaging

Adding in a single strip cardboard is actually a very good idea and it will give you some nifty results. can give you some reference. The main focus of all of this is to create custom mailing boxes that are durable. And in this case, you get that, without having to waste any material too, so it’s the best of both worlds too.

Cornstarch packaging

This is actually a very good idea because it can be adapted and adjusted in roughly any way you would want it to. The customizations and ideas are there, and you will find it super interesting and also quite rewarding. There are some challenges here and there related to it, but if you get past that you will find the experience to be phenomenal and quite amazing every time. Cornstarch combined with other compounds can make some great custom shipping boxes.

Biodegradable plastic

Yes, recycled plastics can be used for custom shipping boxes. Of course, it largely depends on what product you want to send but this can help you a lot. You can have eco-friendly plastics that are fully biodegradable, so that can help protect our planet as well. Plus, you get to have something that works really well and which is fully adaptable to your own requirements. So it’s the best of both worlds basically.

Biodegradable packing peanuts

While not everyone will like to see these in custom mailing boxes, they help protect the item in question and they are fully biodegradable. It’s one of the best things you can add in a shipping box to ensure everything will arrive at the highest possible level all the time.


Leaf plates

The leaf plates are compostable, water-tight and biodegradable. This is a great way for you to protect the environment while also offering stellar packaging that will last for quite some time. It’s certainly the best of both worlds, and you will find the results themselves to be among some of the best no matter the situation. Just try to keep that in mind and use it to your own advantage if you can.

As you can see, there are many ways to add eco-friendly packaging into the mix. You should always try to opt for custom shipping boxes if you can, it helps a lot and it delivers the experience and outcome you want all the time.
