3D printer is a kind of magical printer that designed by Enrico Dini.The biggest differences between the new type of printers and ordinary printers were the morphology and type of printing objects. The former can create the different forms of objects that users thought, while the ordinary printers can only use paper to print text and picture.In addition there is no other purposes. Also, because of this, application areas of the 3D printer were much more than ordinary printers, including medical industry, scientific research, design and manufacturing and so on.


The operating principle of 3D printers is that user first create printing models. Then we should place the models and filaments into the 3D printers. Finally,users should config 3D printer.According to the analysis,program of printer will print objects in a hierarchical form.

In a few years ago, talking about 3D printers may be a new thing for most people (including myself). Indeed, a new thing was initially beginning, it get the support of consumers after a long period of time popularizing and trying. With the 3D printer gradually maturing, the focus center of consumers has gradually shifted from the technique to the price and function. The price of 3D printers has already fallen from thousands down to several hundred dollars.The price of 3D printers from China was from 700 to900, which is the main reason for Chinese 3D printers to get foreign consumers.

Perhaps, many consumers have doubts.For the 3D printer from 700 to900, whether its quality and function can be guaranteed?From the practical application of myself, it is completely don't worry. For example, LXMaker 3D printer is a brand that own high-performance with low price. As a Chinese brand, why would it get ahead? The author thinks that it is mainly determined by the unique features, including the super high printing speed, super large printing volume and super high resolution. Then the author will describe the three aspects in detail.


First is the super high printing speed:Take advantages of the cross shaft structure innovation and the unique design to separate feeding device  with extruder at both sides, instead of Makerbot's heavy printing head (loaded with 3 electric motors, illustrated as below). LXMaker's light & handy extruder guarantees high speed printing. Imagine, if you are running, unloaded or  carrying bags, which is faster? The maximum nozzle moving speed of LXMaker can reach 500 mm / sec .

    The novel cross shaft structure introduced above has win the big prize of "The Best Open Source Hardware"and"The Most Precised and Fastest 3D Printer",nominated by the world-wide well-known Make Magzine.

Second is the super large printing volume:The maximum printing volume is up to 210x210x220mm, outstanding of 3D printers at the same price. (Contact us if you want to customize the printing volume to meet your needs, as large as 315×315×400mm).

Finally is the super high resolution:LXMaker has a very precise Z axis movement, which ensures the precision in practical. The theoratical precison of Z axis is 0.01mm, while the actual test precision is only 0.02 mm, which guarantees the super high quality of the workpiece, and can effectively prevent deformation in the printing process. Ths precision of X & Y axis can also be as high as 0.125mm.


    In summary, 3D printers want to get high sales volume in the future.The most important thing is to improve product price and cut the cost.Only in this way can earned more recognition from all over the world.


iOS Thingiverse app. It is really hard to NOT buy something in the market. (via iTunes)


Makerbot has released an app for those that looking to gain some insight for 3D printing projects or unique gifts, especially since the holiday season is just around the corner. Mobile devices play a big part in today’s fast-paced world and people every day turn to those devices to search for new products or projects while on the go. Makerbot’s Thingiverse is a website for makers who share their digital designs with others of the same community through open-sourced hardware schematics. Mostly, it is set up to sell parts and make money. The site is arguably the largest repository of 3D printed designs on the planet, so users looking for new ideas are sure to find something that will spark their interests. The iOS app was designed for just that, to help users plan and then share their new projects. Users are required to sign up and register a new account or use an already existing account to access the sites content. More people are only online in a mobile capacity – smooth move by Makerbot.

After logging in, users then have access to Thingivers’s database of goodies, with recent uploads showcased and navigated through using a swipable interface. There is also a slide-out navigation bar that allows users to access their accounts as well as app settings. The ‘Explore’ section is the meat of the site, which has all the 3D designs (complete with pictures) arranged from newest to popular designs as well as featured content for any specific category. Each design is complete with all the necessary code for users to print out their creations correctly and completely the first time without the trial and error process some projects have encountered. The downside is that the app itself will not allow users to interact with 3D printers directly but rather saves the design code for use later when needed. Now if they could just incorporate 3D printing technology inside the mobile device themselves...

Ultimaker 2... so afordable... time to embrace the spool. (via Ultimaker


3D printing has been booming as of late. With all the rage manufacturers have created a wide range of 3D printers for users to choose from. Makerbot was one of the most popular printers for a long time and still is. However, one of its closest competitors, Ultimaker, is looking to take that top spot as the hobbyist’s favorite printer. The Ultimaker 2 has been designed and built for people with or without technical knowledge. Getting a printed object out will be easier than ever while it will still possess technical features which will keep the experts interested.


The original Ultimaker was known for its speed and accuracy. The second version will boast those same features along with a larger build volume. It has a 20 micron print resolution along with a build volume of 230 x 225 x 205mm. The prints will sit on a heated build platform which will allow objects to be easily removed when done printing. Sitting on a desktop or workbench the printer will consume an area of 338 x 358 x 389mm. The new Cura software which will process the models for printing is also said to run 60 times faster than typical slicing engines.


Ultimaker founder, Erik de Bruijn, noted, “Speed often has a big impact on the 3D printing experience, and we have spent a lot of time and effort to come up with the fastest technology. Our machine is so fast that the engine finishes processing before you have the opportunity to press print.”


Furthermore, Ultimaker is launching YouMagine, an online 3D printing community. This will be a space where hackers and makers can share their designs and prints. In addition, since Cura is open source along with the printer itself, people will be able to share their modifications to the software or hardware. You may think this is sounds a lot like Thingverse from Makerbot. That is because it basically is except for the fact that Ultimaker is still pushing the open-source philosophy while Makerbot is not.


“We want to give people, for the first time in history, very precise control over how matter is organized with 3D printing. Instead of just sharing .stl files, YouMagine allows the community to share native files. Similar to Google Docs, YouMagine allows for synchronized, shared editing sessions to modify existing designs or team up on new ones. Users can download a file from our website, save to an SD file, print and see the results within minutes. Ultimaker is seeding YouMagine with open source design apps so that users can customize the tools without any programming experience. It is our aim to create a brand new 3D printing experience that doesn't require any specialist skills. By making the process more intuitive, users don't need to know syntax anymore; they can simply take items from a drawer, make a print and see what happens,” commented de Bruijn.


With all the new features, the Ultimaker puts up a good option for the DIY community to consider. However, the price is still not too friendly for the average hobbyist. It is a nice improvement over the original printer and nice to see that no wood is involved in its structure. The Ultimaker 2 will come fully assembled and run for a price of $2750 out of the box.
