Some questions about the hot bed of Ender 3



Creality3D Ender 3 is a great 3D printer, but if you want to buy an Ender 3, you might hear that the print area for Ender 3 is not as large as the print build surface. Ender 3 mentions the promotion Its print area is 220 x 220 mm, but the print platform has 235 x 235 mm, which means that nearly 14% of the print area is unused.
So many people are more curious about why the remaining 14% of the area is left behind?
 There are several main reasons:
 · Machining tolerances: The structure of the Ender 3 is the frame of mechanical joints and connecting rods of various sizes. Each component of any mechanical system has a tolerance associated with the operation used to create it. If you add all potential tolerances, you get a so-called tolerance stack. Additional bed space allows for tolerance stacking in the machine. The king size bed allows for this kind of error in manufacturing. · Bed retention: Unless you have a magnetic bed or print on something that is bonded to the carriage of the print bed, you may have a series of clips that clip the build surface to the carrier platform. The clip that comes with the Ender 3 is an office binder that takes up a lot of space. Adding 15 mm to all sides of the bed makes it easier to ensure that the nozzle does not interfere with the bed retaining clip.
Of course, if you feel unsatisfied that you lose an extra 14% of the print space, we also have a solution available to you. First, you can change the way the print bed is attached to the frame instead of using the binder that comes with the Ender 3 stock. There are two options to change the clip or change the print bed.
 Cut the clip: Switch the binder to get the low-key options like these photo frame springs. The advantage of these frame springs is that they can be locked in place and remain stable. If your printer goes down and enters them, they will also have enough power to remove them.
Replacement of the printing bed: The printing bed must be clamped with a magnetic bed that must be used with Creality so that it can be mounted directly on the construction surface of the Ender 3. The flexible build platform easily strips the magnetic base and allows you to distort it, making it easier than ever to remove prints. However, please note that the performance of the magnetic bed begins to be higher than 60 ° C, which means it is not compatible with ABS filaments.
  1. Since the print does not have a bulky binder, let’s talk about the second step: programming the 3D printer to actually use this space. To unlock the true potential of your Ender 3 bed size, you need to update the motherboard computer’s firmware. There are two basic steps to opening a larger bed size:
  2. Exchange firmware: By default, Corey’s Ender 3 firmware only allows you to use a 220 x 220 mm print surface. However, Creality’s firmware is an older and more basic version of the official Marlin RepRap firmware. (Creality has made some changes to make the software work with Ender 3.)
  3. Modify the code: Once you have the latest version of the firmware, you can make the necessary changes to the bed size in the Marlin code and refresh it to your printer. Changing the Marlin code requires some experimentation. For safety reasons, we recommend a maximum bed size of 230 x 230 mm. (Increase 9%!) Please note that while refreshing the firmware may seem extreme, it also adds protection against hot end runaway protection and more advanced controls.
Creality decided to use the available Ender 3 bed size to set the firmware to be less than the actual size of the build platform, measuring 220 x 220 mm. This sounds logical when you consider tolerances and bed fastening. But does each edge really need 15mm?
 Technically, the answer is “no.” A 5 mm lip should be enough. Therefore, we have reviewed how to achieve a 230 x 230 mm print area by modifying the print bed and firmware of the 3D printer.
 It is not recommended to set the size of the Ender 3 bed to a full 235 x 235 mm, as edge printing can cause problems. But feel free to play with it and find the one that best suits you and your Ender 3.

What types of 3D printers are there? After reading these pictures, I finally understood.

The first category is the FDM printer, which is also the printer that is seen on the market. About 60% of this year is selling FDM printers. FDM printers are rapidly formed by fused deposition, the main materials ABS and PLA.
The second category is SLA printers, which are seen in the market. There are fewer domestic sales, and there are relatively few domestic sales. The main reason is that model players and families buy desktop-level SLA printers. This type of printer is formed by photocuring, the main material is photosensitive resin. The price is more expensive than the FDM printer, but it is highly accurate and can meet the requirements of model players and home users.
The third category is the 3DP printer, which is relatively rare in the market and is mainly used for industrial production. Because the price is relatively high, families and schools generally do not purchase such printers. This type of printer is bonded by three-dimensional powder. The main material powder materials, such as ceramic powder, metal powder, plastic powder.
The fourth category is SLS printers, which are relatively rare on the market, mainly for industrial production and military industrial production. This type of printer is made of selective laser sintering, the main material of the powder material.
The fifth category is LOM printers, which are relatively rare in the market. Currently, there is no need for such printers in life, but it still has value. These types of printers are manufactured in solid parts, mainly paper, metal film, and plastic film.
The sixth category is DLP printers, which are seen in the market. There are relatively few domestic sales, and there are relatively few domestic sales. These printers are formed by photocuring, and the main materials are photosensitive resins. It is highly accurate and can meet the requirements of model players and home users. This type of printer is similar to an SLA printer.
The seventh category is the FFF printer, which is also the printer that is seen on the market. FFF printers are manufactured by fuses, the main materials are PLA and ABS. It’s cheap and you can print anything you want to print. The disadvantage is that the accuracy is not high, the printing speed is slow, and the surface is too rough. Similar to an FDM printer.
The eighth category is the EMB printer, which is mainly used in human bones and military aerospace industries. The EMB printer is formed by electron beam melting, the main material is titanium alloy.
At present, 3D printers have not yet been clearly classified, but we can still classify them according to the characteristics and functions of 3D printers. Of course, many 3D printers are not listed.

Why is this shipment of FDM 3D printers from the Creality3D up to 100,000+?

Ender-3 was launched in March 2018, and its shipments abroad have already exceeded 100,000 units. It has formed a large user base at home and abroad in just a few months. The global search list of Google search 3D printers quickly climbed to the top. Location, after the CR-10 (YouTube's number of videos reached more than 10 million, a single pageview of hundreds of thousands of times), another popular global product.

All3dp highly recommended, Ender-3 became the first price of less than $ 200, and is the most popular.

Users use the Ender-3 printer to upload videos to YouTube, a large number of 100,000+ plays
.

So why is it so popular?
Let us look at the feedback from many customers:

     1、Very satisfied, I thought I could only play a toy. The result was very high when it was printed back. It is completely beyond my imagination. Go online and download some models to print. The models you make yourself can also be printed. It's just perfect!
     2、The first purchase of 3d printer, pure novice, through the assembly and debugging of one night, the first small work is completed, and the subsequent adjustment parameters are refined, which is generally suitable for beginners, cost-effective, I hope that your family's products will become more and more it is good.
     3、The overall is still good, that is, the instructions for use are not detailed enough. The original cushion is the loss product, and the printing options should be debugged according to the product itself. Some are suitable for printing support, some are not suitable, but the effects are different. Not the same, the upper surface effect is still quite good, the lower surface is almost a little, and the benevolent sees the wise and sees the wisdom, learning to have one, pretty good, small investment.
     4、Deliberately evaluate after using it for a while. The printing accuracy is the same as expected, as shown in the figure. High-precision printing takes a little longer, but after all, it's desktop-level, it's already very good, and I plan to try it myself later. Very good shopping experience.

     5、A super cost-effective printer, personal feeling is very cost-effective, can be said to be very good in the thousand yuan printer. I am an amateur creator, I like DIY gadgets, but I don’t have enough tools to make it, and I’m not interested in it. After buying Ender 3, I suddenly felt that I could do it, and my heart was flying. I bought it for almost half a month. At present, the machine is running stably and the accuracy can meet my 99% demand. It is very good.
     6、Printed things, choose higher precision, the effect of printing is good, it is very good to use for trial. The 0.15mm print puppy can't be finished at night. It can be continued to print after power off.

     7、The first time I used a 3D printer, it was a slap in the beginning. The so-called leveling is not so difficult, just use a piece of printing paper in the middle of the nozzle and the platform. That is, I always make mistakes and reversals. As a result, I accidentally put a small print on the heating table. In short, it took about 2-3 hours to get roughly clear. Inserting the consumables was the most aggressive. At first, I didn't understand what it meant to insert the consumables into the nozzle. The result was a little bit inserted at the entrance, and the result was empty for a few minutes. You must pay attention to the consumables until you squeeze the red test consumables into the front of the small nozzle to complete! The customer service is very good, the question is answered very quickly, and the slicing software is basically understood at a glance.

Overall, this Ender-3 printer is positioned at the entry level, and most people in the real world have heard of it but have not really touched the 3D printer, but they also want to make something to try or use in life. The quality of the machine itself is good, the use of the player is low, the user is easy to get started, and, for the price of about $200, a large number of users are willing to try fresh, and then order to buy.

How to choose a 3D printer glass hot bed board?

The hot plate of a 3D printer is not the best, only the most suitable, usually depending on the model and consumables you want to print. But if you’re looking for a way to make the model base smoother or easier to separate the model, glass hotbeds are definitely the best fit.

The 3D printing forum circulated a story about the “easy separation” of the glass hot bed. A netizen accidentally bumped into the 3D printer and the model being printed was lost. Of course, this is a bit exaggerated. The glass hot bed still has many advantages:
 1、flatness
 The hot bed needs to be flat throughout the 3D printing process to avoid errors. The glass has a high modulus of elasticity and good thermal stability, which ensures that the overall flatness of the hot bed is always consistent. After all, leveling and calibrating is a tedious process.
 2、smooth surface
 Designers want the bottom of their work to be as smooth as possible, and the glass guarantees such a smooth finish, providing a mirrored glossy base that most bed surfaces cannot. And because flaw can be transferred to other parts of the model, the rough bottom has been unpopular.
3、Cost
 Due to thermal expansion and contraction, many hot bed surfaces cannot be reused. For example, a plastic or acrylic substrate needs to be replaced after a few prints because the surface will begin to peel off. But glass rarely needs to be replaced because it is hardly worn and can be used for multiple 3D printing without replacement. Durable glass like tempered glass does not easily break or rupture when exposed to high strains. The glass hot bed can save a lot of long-term costs and the trouble of replacing the hot bed.
 4、Easy to clean
 The hot bed will leave grease, dust and unwanted plastic fragments after use, resulting in uneven print surface. Therefore, they need to be wiped occasionally to ensure they are kept clean before printing. Unlike most beds, the glass 3D printer hot bed is very smooth and makes it easier to spot dirt on the glass platform. This makes it easier to clean with acetone or plain glass cleaner.
 5、Easy to disassemble
 When removing a print from a hot bed, it takes time and effort, and accidentally damages the print and wastes time. The separation of the glass hot bed is relatively convenient.
6、Themal conductivity
 The plastic is unevenly heated and warps when cooled. The hot bed usually needs to be heated and kept at a certain temperature to prevent warpage and improve print quality. The glass hot bed is excellent in thermal conductivity and is easy to maintain a stable hot bed temperature.
 7、Scratch resistant
 Hot beds like acrylic are easily scratched and can get cumbersome when printed. Tempered glass is often scratch-resistant and less susceptible to abrasion or chemical damage. After using a solid glue or adhesive sticker, it is necessary to use a doctor blade to scrape the entire hot bed when the sticker is worn. The glass bed does not have such a problem.
 Factors to consider when purchasing a glass hot bed
 1、Size
 This is a very obvious parameter. The glass plate needs to fit snugly against the platform to avoid vibration during printing. If it is too large or too small, the bottom plate clamp will not be used.
 The other is the optimum thickness. The 3–4 mm glass hot bed is a standard thickness that is sufficient to maintain strength and heat dissipation. If you choose a very thin glass plate (for example, 1mm), it is easy to crack due to high temperature or accidental contact with the hot end. The thickness should be selected for the size of the test bed. For large hot beds, a thickness of 6 mm may need to be considered.
 2、Themal shock resistance
 High-performance glass does not break when the temperature changes rapidly. This durability is called thermal shock resistance. When choosing the temperature of the 3D printer nozzle, choose a suitable glass hot bed.
 3、Heat resistance
 Even with tempered glass, repeated heating and cooling can cause it to lose strength. However, there are still a lot of special glass on the market, which can be considered if it is often used at extreme limits. For example, ceramic glass can be used at extremely high temperatures, with consistent strength and without the effects of heating and cooling cycles. Another commonly used glass plate is borosilicate glass, which consists of boron trioxide and silicon dioxide, which is resistant to thermal expansion and thermal shock, and exhibits little physical change at high temperatures, with significant thermal properties and Almost indestructible, it is ideal for use as a hot bed for 3D printers.
