What makes Mizar M different?

Separate Mode VS Gradient Mode

Traditional monochrome printing has been difficult to meet the creative needs of 3D printing enthusiasts, and mixed-color printing has become the future trend. Mizar M 3D Printer has two print head modules, “Separated Color Module” and “Gradient Color Module”, and is designed for quick replacement in structure. After replacing the print head module and inserting the hot end connector, the system will intelligently identify the print head module and enter the corresponding print mode.

Unique Separated Color Module

Compared with the Gradient Color Module, the Separated Color Module of Mizar M can realize printing a single color without mixing another color when printing models with two color filaments. Besides, it gains a faster printing speed, which can better meet the needs of two-color printing.

Patented gradient color technology

The Geeetech R&D team has optimized and upgraded the Gradient Color Module of Mizar M. Compared with Geeetech’s first-generation multi-color 3D printer, the Mizar M Gradient Color Module has redesigned the color mixing flow channel and a structure to prevent the reverse flow of melting filament. The filament is more uniformly mixed in the hot end. This special design effectively solves the problem of uneven color mixing, and the hot end blocked due to the reverse flow of the melting filament. At present, the gradient color structure has applied for a patent.

Mizar M with a printing size of 255 x 255 x 260mm, supporting auto-leveling and manual leveling, is equipped with a fixed hotbed and 32-bit silent motherboard. Responding to two printing modes, it comes with double UI interaction systems. The machine comes with a dual-drive gear extruder and double Z-axis ensuring high printing quality. At the same time, Mizar M is designed with a belt adjustment kit, nozzle LED light, filament detector break resuming capability, etc.

Industrial designer John Mauriello,based in San Francisco,broke the conventional thinking and put the effort into his Coral Lamp Lighting Collection with something else entirely.

These lamp prototypes took their inspiration from different types of corals coming with varying aesthetics. Mauriello selected only three prototypes from hundreds of them to produce: the Timor, the Sargasso, and the Celebes.

Before 3D printing these Coral Lamps , Mauriello firstly developed the computational algorithms that mimic coral growth patterns,which show the “growth” of the lamps as they come into being. And, more remarkable,all three lamps were 3D printed in the USA, using processes which recycle waste material in an attempt to reduce waste and curb carbon emissions.

The Coral Lamp Lighting Collection is Mauriello’s way of paying tribute to the ocean’s beauty.As an senior surfer,Mauriello’ve experienced the beauty and power of the great ocean,in which coral is one of many magical living structures with all sorts of shape, scale and color.Mauriello’s lighting celebrates this thriving life created by an entire coral ecosystem.

Without a doubt, you can’t bear some minor flaws in the surface of a 3d printing model, let alone “String”. You complained that this printer is such trash contrary to expectations. At that time, you may get mad but it will eventually end up in a mess. So firstly you need to calm down. Take a close look at what is the exact problem, make it clear how it happened, and how we can solve the problem. Let’s dive in.

What’s the Problem?

3D Printing Stringing exists when small plastic strings are left behind on a 3D-printed model. This is usually due to plastic leaking from the nozzle as the extruder moves to a new position.

How to fix this？

In this article, we bring 5 solutions that can be commonly used on all the major 3D printers.

1. Enable Retraction

Enabling retraction is the most ordinary way to fight against 3D printer stringing. Enabling retraction means that when the extruder has to pass through a gap, the filament is retracted a little bit by the feeder. Once the extruder reaches the next position, the filament is pushed out and the print continues again from the nozzle. If the retraction setting is turned on and you’re still experiencing 3D printer stringing, you may then need to go into the details of the retraction settings:

• Retraction distance

The most important retraction setting is the retraction distance. This determines how much plastic is pulled out of the nozzle. Generally speaking, the more plastic that is retracted from the nozzle, the less likely the nozzle is to seep out as it moves. Most direct-drive extruders only require a retraction distance of 0.5-2.0mm. If you run into stringing with your prints, try increasing the retraction distance by 1mm and test again to see if the performance improves.

• Retraction speed

The next retraction setting that you should check is the retraction speed. This determines how fast the filament is retracted from the nozzle. If the retraction is too slow, the plastic will slowly leak out of the nozzle and may begin to leak before the extruder moves to its new position. If you retract too quickly, the filament may separate from the hot plastic inside the nozzle, or the rapid movement of the drive gear may even grind away pieces of your filament. There is usually an optimal retraction point between 1200-6000 mm/min (20-100 mm/s).

If standard retraction isn’t doing the trick, you can try to reduce the minimum travel. This is usually the quickest solution to fix stringing issues. Drop the value by 0.5mm until the stringing has stopped completely.

2. Set the Right Temperature

The 3d printer extruder temperature is the next most common cause for stringing. If the temperature is too high, the plastic inside the nozzle will become less sticky and more likely to leak out. However, if the temperature is too low, the plastic will be one kind of solid and difficult to extrude from the nozzle. If you thought you had the right retraction settings but still have these problems, you can try to decrease your extruder temperature by 5-10 degrees. This will greatly improve the quality of your printing.

3. Movement Speed

Moreover, increasing the movement speed of your machine can also reduce the time it takes for the extruder to leak as it moves between parts. The X/Y Axis Movement Speed represents the side-to-side travel speed and is frequently directly related to the range of time your extruder spends moving over open air. As long as your machine can move at higher speeds, increasing this setting may reduce stringing between parts.

4. Thoroughly Clean the Nozzle Before Printing

When you use a printer for a long time, the filament can leave a thin residue layer in 3d printer nozzle. This thin layer can cause 3D printer stringing as filament strands will try to stick to the surface of your printed part. To avoid such a problem, ensure your nozzle is thoroughly cleaned before print.

5. Keep Your Filaments Moisture-Free

PLA, which absorbs more water than ABS, is the main culprit. The water turns to steam when the plastic is heated up, and it can mix with the plastic to increase the likelihood that it will seep out during non-printing movements.

Therefore, it is very important to store the filament properly, especially if you live in a humid environment. For more guidance, check out the previous blog here：How to store filament? 

Currently, more than 100,000 people in the United States are waiting for organ transplants.Kidney patients account for most of the demand, with more than 90,000 people seeking donor organs.Statistics show that 17 people die each day while waiting for new organs.At the same time, a new patient is added to the waiting list every ten minutes.So the American company United Therapeutics paid the Israeli company CollPlant 3 million dollars to speed up the production of the famous Bioink, called rhCollagen.This will provide ideal characteristics for bioprinting, including optimal rheology, greater safety, bio-compatibility and adjustable physical properties.It can also be compatible with a variety of  technologies such as extrusion, inkjet or stereolithography.

Bio-printing is a particularly interesting technology for the medical sector, allowing the creation of human tissue and treatments that is suitable for each patient.Every day, methods are evolving and innovations are emerging, which means we’re sure to see functional organs being 3D printed within a few years.The good news for those waiting for transplants is that Bioprinting can design livers, pancreases, spleens and even kidneys.The companies CollPlant Biotechnologies and United Therapeutics Corporation have recognized that this technology could be the future of tailor-made medicine.

In October 2018, the two companies began a collaboration: United Therapeutics received an exclusive license for the CollPlant technology to produce and use bioinks based on human collagen for bioprinted lung transplants.Two years later, the partners began working on a kidney, an organ in need of a donor.CollPlant Bioink is made from human collagen.It requires very strict purification conditions, which makes it extremely long to process, but most importantly it is difficult to produce on a large scale.So the Israeli company relies on a plant platform to produce collagen.They explain: “The production of our recombinant human type I collagen (rhCollagen) starts in genetically modified tobacco plants. The recombinant human protein in the form of ‘procollagen’ is extracted from the leaves of mature plants and processed to produce a highly purified rhCollagen that can be used for the production of medical products.” This innovation will help develop bioprinting and regenerative medicine, provide an opportunity to create quality bioinks for the eventual design of different types of organs.

Thanks to the attention paid by the American United Therapeutics Corporation,the manufacture of kidneys is being addressed in hopes of reducing the number of patients waiting for transplants.

Are you a seasoned player in 3D printing, wondering what you can do with all your 3D designs, models and 3D printer, aside from keeping them as a hobby ?   

If either of the above scenarios apply to you, you are not alone. Alex, China born and bred, now 27, working and living in Europe, first got into 3D printing when attending university in France. He says one summer afternoon in his sophomore year he ,together with his other three classmates was invited to a small gathering at a local student’s house. At some point his friend showed the guests his 3D printer and started to print a Japanese cartoon character on it. Alex was amazed at how capable this little(well, not exactly little, but Alex thinks so ) machine is.

A few days later, Alex decided to get one himself. So he went online in search of the same 3D printer model his friend was using. As it turns out, the same machine being sold online is priced at $399,not a small expenditure given that he was a student studying overseas and his middle-class family background. He somehow summoned up the courage to ask his parents to buy if for him. According to Alex, his parents were mad at him at first. They wouldn’t get it why he would want to buy such a “useless” but expensive thing. And they were worried that their only son would abandon his study as a result of “playing too much with the machine”.

Long story short, in the end, Alex was able to convince his Dad to buy the printer for him by promising to focus on his study and to return home with a degree,which he did. Fast forward to 1.5 years ago, Alex purchased his first geeetech 3D printer–A20M, and has become a fan of geeetech ever since.

To date, a great number of people still have not heard of desktop 3D printers,just like Alex and his parents years ago, and 3D printing is more of a industrial concept than an everyday conversation topic.

It is projected that 3D printing will be the next big thing in the years to come,with 3D printers for home and office use being more affordable and capable.A similar pattern can be drawn in the developments of smart phones and 3D printers. Smart phones in the early days were expensive,not so “smart”, and known to few.However,a decade later almost everyone owns smart phone. So now is probably the best time to monetize your 3D printing skills and expertise before 3D printers become ubiquitous.

Here are 5 ways to make money with your 3D printer and 3D printing know-how.

Sell Your Design.

One of the best ways to make money using a 3D printers is not to have one. Isn’t it amazing? If you have 3D models/designs you think are great but do not own a 3D printer, put them up for sale.The world is in want of great designs. .

Sell Your Work

If you are a creative creature, why not turn your creativity into reality and sell your work online? Take photos or make videos of your works and make them known to others. Share them on your social media:Facebook, Ins. Twitter. Those impressed with your work may be willing to pay for it. Photos/videos of your printed objects are promotional materials to get customers.

Prototyping

Another way to make money off 3D printing is to sell 3D printed prototypes to local businesses and companies. One advantage of this business model is that you do not have to rack your brain trying to come up with great designs or models. Chances are your clients have a team dedicated to it. All you are left to do is get them printed. It of course would give you a leg-up if you have a good command of 3D modeling (CAD) software.  

Printing Services.

As pointed out above, not every one owns(some choose not to ) a 3D printer. 3D printing has been widely used in education, medical, robotics,architecture,jewellery and many other industries, this means there is always a market for printing services.  Let others know what your printer is capable of and your rates for such service,and you are all set.

Teaching 3D Printing.

As of today,3D printing is still not commonplace, but is getting more attention and interest from the public, and 3D printers are being introduced into classrooms, offices and homes due to their versatility,causing a gap between the demand for 3D printers and supply of experts, specialists, who understand 3D printing and know how to operate those machines, flying in the face of the fact that desktop 3D printers are becoming more and more user-friendly. All this makes teaching 3D printing technology a lucrative business.

That concludes the list of ways to make a living off 3D printing.

You just comment “Huh, neat” grab the drink and enjoy getting high. After all only what is inside the bottle matters. Few people realize just how much work goes into packaging, redesign, or how it actually does impact the buyer. Even on a subliminal level. Many big teams of designers work to get a new look which is just perfect. While the manufacturer evaluates the costs and decides if a change is worth it.

Rather than throwing away the bottles and adding up to the pollution, you can take a step to revolutionize things. Therefore, this article will tell you exactly how you can. We have bought good news for you, so get excited.

Beer Bottles 3D Printed

The Australian Beer that recently underwent bottle makeover is James Boag’s.  The makers of the bottle were thinking about getting a makeover done. But also thought about whether it would be worth the money. They didn’t want to make a change just because they could; the new design decided would have to be attractive enough to be well-received by customers. They were hoping to make this determination before significant time and money were spent on the redesign.

The packaging company Orora, that supplies James Boag’s bottles. It decided to go for a 3D Printing prototype for the best outcome of redesigning. The organization contacted 3D Systems On Demand Manufacturing, which went up against the challenge of making a 3D printed bottle. With an indistinguishable clearness and tone from glass, and also the same close by heave new bottle. Using SLA 3D printing technology and VisiJet SL Clear resin, 3D Systems 3D printed four prototypes. Hence, countering the disparities in weight by adjusting the interior wall thickness of the design file based on the density of the resin. They also carefully color-matched to get the same green as the original bottles.

3D beer bottle makeover got hit

Subsequently, being 3D printed, the bottles experienced an in-house completing protocol that included wet and dry sanding and the application of a surface tint and last clear coat. As per Tracy Beard, General Manager for the On Demand Manufacturing office in Lawrenceburg, Tennessee, a large number of clear parts are delivered each week in that office alone.

It took just seven days for the models to be finished. And soon thereafter they were furnished with labels and caps and loaded with fluid. They were then placed in a shop for observing, and criticism demonstrated that the new plan was a hit. Finally, giving James Boag’s group the certainty to proceed with the full overhaul.

Thus the Boag’s  Company did a makeover of their Beer Bottles with help of 3D Printing. So now you can also have a 3D Printed beer bottle as an aesthetic in your house. Thus you even don’t throw the bottle and keep it with you.

During the initial stages of 3D Printing, the whole object had to be printed using a single material. That’s impossible because you can’t print a house or fashion accessories with a single material.Thus Multi-material 3D Printing, prints a single object with two or more filaments rather than just using PLA, ABS or any other filament.

This is a bit tricky! You can use a dual extruder printer or get things done with a single extruder printer itself.

The question is how?

A Dual extruder has multiple extruders that allow you to have multiple filaments ‘piped in’ and ready to be used whenever the object being printed requires them, and this is where the saved time comes from.Having different filaments ‘ready to go’ means you no longer have to pause a print, empty out the extruder of the previous filament, feed in the next filament, and resume the print every time you need a different material. The printer will simply call on which filament it needs when it needs it.

While with a single extruder when you want to print a multi-material thing you have to replace the previous material with the other one and then print it. This takes time as in 3D Printing it prints layer-wise and if you have multiple layers of multiple materials than it requires a lot of time just changing the filament.

How to create a multi-material print with a Single Extruder printer?

The secret? Spread the different materials across different layers of a single extruder printer. Both of the models that are shown have the materials at separate heights; on separate layers. The process basically works by printing with one material to a certain height, pausing the printer, switching materials, and continuing the print.

Step 1: Choose your 3D Model

Icecats has explained this with really well with an example of printing a toilet plunger as it has a flexible filament and a wood filament.So you need to find a good 3D model from Thingiverse or MyMiniFactory or any other 3D Printing website. You need to keep certain things in mind like:

• Choose the object wisely which makes sense of carrying out a multi-material printing process.
• Keep a certain height within two materials as this is the key to the process like the flexible plungers base is lower than the wooden handle.
• See whether the model is printable with the desired materials.

Step 2: GCODE and other settings

• Slice your 3D Model into a GCODE with your 3D Printers host software.
• Look up the speed settings into it and then set it up to the slowest.
• Find a proper balance of layer height, infill, and retraction settings for your prints.
• After you are ready, heat the printer and fill the first material into it. You can change the temperature later when you want to fill in the other material. The first material used by icecats was Ninjaflex.

Step 3: Switching materials

• Monitor the printer as the first material is extruded.
• When you want to switch the material, just pause the printer, it usually takes a bit of time for the printer to stop, raise the printer to 10 mm height on the z-axis.
• To prevent the leakage you need to place a piece of paper below the extruder. If necessary, adjust the hot end temperature in the Manual Control tab to suit the second material.
• Switch to your second material and purge the extruder until the new material comes out pure. Remove your piece of paper and continue the print. Repeat this process as many times as necessary.

Step 4: The Final Results

Icecats tells how his 3D Print resulted in, he basically used two different  PLA/NinjaFlex and wood/NinjaFlex. He says that both tests worked well for him.The purple and white cylinder shown above was printed with PLA and NinjaFlex. He has stressed that the print until it broke- two PLA layers spit apart, which means that the NinjaFlex/PLA bond is actually stronger than the PLA/PLA bond! The bonding between the wood/NinjaFlex was similarly high strength.

Here are some other ideas for prints to try.

• hard PLA/ABS box with NinjaFlex hinge
• hard PLA/ABS model car with NinjaFlex shocks and tires
• wood “table” with PLA/ABS legs

Thus you can try multi-material printing with your single extruder printers as well and give your prints the real touch as you want.

At the brand’s Fall-Winter 2018 show in Milan. Gucci designer Alessandro Michele sent models down the runway carrying duplicates of their own headless domes. Gucci may well be the hottest brand in the world. That suggests that its favorite maximalist trends. All-over prints, endless logos, animal pictures, embroidery—trickle all the way down to the remainder of the style world.

Fashion lovers were shocked at Gucci’s freaky catwalk show that saw models strut their stuff carrying fake heads. Whereas the fashion things were spectacular, two of Gucci’s models stole the show by taking to the runway carrying 3D printed replicas of their own heads.

Unsurprisingly, the 3D printed heads have caused quite a stir on social media and have even been the inspiration for a number of funny memes.

Now lets Star Trek Online captains 3D print their starships:

March will be a great month for spaceship captains within the Star Trek online universe. Partnering with cloud 3D printing business Mixed Dimensions, Star Trek online will, come March, enable gamers to 3D print their own personal starships from the sport as 12-inch organic resin models. The new in-game feature will direct gamers to Mixed Dimension’s GamePrint internet site, which will offer different purchase choices.

Nearly all the five hundred playable starships will be created 3D printable, whereas personal customizations like ship names, colors, and defend skins will all be incorporated into the print. On the cheaper finish, gamers can elect a single-color or pre-primed model, however, people who need their ship rendered within the most magnificent detail will select a luxury hand-painted possibility.

3D printed Custom Prosthetic Arm:

In the UK, a father has 3D printed a custom prosthesis arm for his 10-year-old son, who was born without a left hand, while across the pond in Missouri, a teenager has 3D printed a custom prosthetic arm for his veteran amputee father. Teenager Robbie Freis used his 3D printing skills to fabricate a new arm for his father, a veteran who was injured in a 2003 RPG attack in Iraq. It was a touching attempt, though Freis did have one ulterior motive for his project: getting his dad back on the video games!

It’s a beautiful picture of 3D printing in 2018.

3D printing does great things in a lot of areas, but one of the most directly beneficial uses for the technology is prosthetics. All around the world, there are many organizations who are dramatically cutting the cost of prosthetic limbs for those in need, while individual makers are also designing and 3D printing their own prostheses using homemade designs or models sourced from the internet.
