3D printing service firm latest news. 3D printing is a relatively new technique in the manufacturing world. Let’s start with some examples, focusing on 3D printing applications in the modern world.

In the last several years there have been many 3D printing applications in the world of medicine. They range from bioprinting – where biomaterials such as cells and growth factors are combined to create tissue-like structures imitating their natural counterparts – to medical devices like prosthetics. 3D printed prosthetics exemplify 3D printing’s versatility. It is difficult and expensive to produce prosthetics that fit a patient. With 3D printing, measured prosthetics can be modeled and printed at significantly lower cost. Children in need of a prosthetic formerly had to wait to get one to be sure they would not outgrow it. Now, a new prosthetic can be 3D printed for them every few months. In some third world countries, prosthetics are not even an option, they can now take advantage of 3D printed ones.

We’re not going to make a futuristic list of futuristic printing things without robots! This robot’s body was built entirely by 3D printing, except for the motor. Printing it this way allows for cheaper and stronger parts, and no waste of materials. What you see above is the result of sugar, food dye, and creativity – and, of course, a fancy 3D printer. Right now, the 3D Systems ChefJet can make these bright and stunning sugar cubes (or diamonds or balls) in just about any intricate and delicate shape you can imagine.

Searching for 3D printing services in Denver? If your project requires a prototype not suitable for our printer, or one that requires a completely different process to create…we know people. We have a vast network of domestic and foreign resources at our disposal to help you get your project off the ground. Whether it’s bringing your product to life, or helping you design, model, and 3D print a jig for a complex machining project, we’ve got you covered. We leverage a decade of product development experience to make your vision a reality, and help you achieve your prototype and production goals. See extra details at Product Development Services.

Stereolithography is a term coined by Chuck Hull in 1986, after he patented it as a method of creating 3D objects using UV light and a liquid photopolymer. The initial design used an ultraviolet laser that focused the beam at the bottom of a vat of resin. The laser would harden the resin for that layer, and the model would be lifted, and another layer created beneath the previous. This built a 3D object by adding successive layers. This technology was taken to market by 3D systems, who developed a range of SLA 3D printers that are still in use today. One of the major advantages of Stereolithography is the ability to create very high quality parts with minute surface detail. By using a laser or DLP projector, today’s printers can resolve details as small as just a few microns across. This makes Stereolithography ideal for creating jewelry and other finely detailed objects. And like FDM, the patent for this technology has also expired, allowing for a large number of printers to be available on the market.

We market a chemical free cleaning cloth that cleans any surface streak free, spot free, lint free with just water, washable and reusable for 3 years. This is the original streakfree cloth american made. Cleans mirrors, glass, windshields, stainless steel, granite top counters spot free lint free. The most incredible cleaning cloth ever, clean almost everything with just water. See more details at Streakfree washable reusable cloth.

Most things that seem too good to be true, usually aren’t. However, these “towels” aren’t one of those things. I was skeptical, but after using them to clean my car windows, I’m a believer! Simply amazing! Just wet it, wring it out, and go to town. NO STREAKS!!!!!!!!! I recently spent $8 on a dedicated class cleaner that works pretty well, but this is just tons easier and does a better job. I still can’t believe how easy it was to *finally* get clean, streak free windows!

Love these cloths! They clean mirrors and glass perfectly and don’t leave any streaks! I just tried them on my car and they left it looking new again. They require minimal effort as you don’t have to go back and fourth multiple times like with regular glass cleaner. I would definitely buy these again! Amazing! Just cleaned my first mirror. No streaks! Have been using microfiber cloths for years…does not compare to this cloth. Will buy this product again once I wear this out. (Glad I bought two) Happy to find something that cleans without streaking. My husband just did our windows and mirrors today. Before we had blurriness and streaks everywhere. We were both amazed at how beautiful the windows and mirrors now look, streakfree and no more blurs. We love these cloths. So glad I purchased forty of them right away.

The Streak Free Microfiber Cloth fiber is made from a special yarn that is 0.1 denier, an ultra fine Micro fiber. This filament is very fine, strong and is virtually lint-free. The wedge-shaped polyester shown in this cross section, together with the core nylon, fits the surface of any object and gathers dust efficiently.

Machine wash with laundry detergent or hand wash with dish soap in hot water. Rinse thoroughly. Using bleach will shorten the life of your micro fiber cloths. Do not use fabric softener (fabric softener leaves a film on the cloth and decreases its effectiveness). Be careful when machine washing or drying in mixed loads as micro fiber cloths will pick up lint from other fabrics. Air-dry or put in dryer on low to medium heat. Source: https://streakfreexl.com/.

Spot welding of very dissimilar metals, such as aluminum and steel, is generally not possible because of different melting characteristics and conductivities. Some types of coated low-carbon steels require special techniques. Steels plated with chrome and nickel for electrical conductivity can usually be resistance welded as readily as uncoated material. Aluminum, tin, zinc and terne-coated steels are also spot weldable with special precautions and welding equipment. Some coatings can emit poisonous fumes that must be safely handled when spot welded, thereby increasing cost. Spot welding of coated substrates creates burn marks in the coating which can be unsightly and may corrode in severe environments. Designers should carefully consider the product’s appearance and service requirements before specifying spot welding of pre-plated materials.

Start off by drilling 7.5mm holes in the front sheet of metal at a spacing of normally 25mm to 40mm (or whatever the original spot weld spacing was). Then clamp this sheet onto the back sheet. 7.5mm is a reasonably good hole size for 0.8 or 1.0mm sheet. Thicker sheet might require a slightly larger hole size. Try a little test piece out like this one before welding a whole sill onto a car and check the weld has penetrated through both sheets.

The welding heat is generated by the electric current, which is transferred to the workpiece through copper alloy electrodes. Copper is used for the electrodes as it has a high thermal conductivity and low electrical resistance compared to most other metals, ensuring that the heat is generated preferentially in the work pieces rather than the electrodes. The amount of heat depends on the thermal conductivity and electrical resistance of the metal as well as the amount of time the current is applied. Other materials commonly spot welded include stainless steels (in particular austenitic and ferritic grades), nickel alloys and titanium. Read extra info at Tecna Spot Welder Parts.

Electric welding relies on the Joule Effect. This is the thermal result of the electrical resistance, occurring when an electric current passes through a conductive metal – in this case metal sheets for assembly. If that last sentence went over your head, here’s how it works: to weld two or more sheets together without adding a filler metal, they are tightly compressed between two heat-resistant electrodes (i.e. non-melting), generally made of copper, and a high-intensity current is applied to melt the plates together at that point. The result is a small merging of metal which constitutes a welding point. The welding time is very short, between one and two seconds, and the shape of the resulting welding spot depends on your choice of electrodes.
