Components

Creates support structures

✖Zeepro Zim 3D

The printer will automatically build extra structures to support the item as it is printing. The extra support can then be easily removed.

Has a heated build platform

✖Zeepro Zim 3D

A heated build platform helps keep the lowest levels of a print warm as the higher layers are printed. This allows the overall print to cool more evenly.

1.75mm filament diameter

✔Zeepro Zim 3D

The 1.75mm filament diameter is gradually overtaking the previous 3mm standard. The 1.75mm filament feeds into the printer with greater ease and allows for more detail in the printing process.

nozzle size

0.35mm

The smaller the nozzle, the more detailed the final product can be. However, when speed of printing is of greater importance than detail, a larger nozzle may be preferable.

3D print speed

110mm/s

The speed at which 3d objects are printed, measured in millimeters per second.

number of extruder heads

More extruder heads allow you to use different colors and different types of material at the same time. A second extruder is also required to build PVA/PLA support structures around items as they are printed.

Has an automatic platform calibrator

✖Zeepro Zim 3D

This feature saves time and effort in terms of maintenance, however the build platform itself still needs to be manually levelled.

Prints in hollow mode

✖Zeepro Zim 3D

Hollow mode will build the item quickly and using less material. This will allow you to print quick prototypes of your designs before printing a solid model i.e for presentational designs rather than functional solid ones.

Materials

Prints in PLA

✔Zeepro Zim 3D

Polylactic acid (PLA) is popular in 3D printing as it cools and sets quickly. Unlike ABS plastic, it is biodegradable and therefore better for the environment. It can be used to build support structures for other printouts, as it can then be dissolved leaving no marks.

Prints in full color

✖Zeepro Zim 3D

Similar to regular 2D printers, this type of 3D printer mixes different colors between cartridges. This process allows the printer to reproduce the color spectrum, therefore allowing you to print in almost any color.

Prints in HIPS

✖Zeepro Zim 3D

The printer is able to print in High Impact Polystyrene (HIPS). HIPS is similar to ABS plastic, but uses different solvents (limonene rather than acetone). HIPS is easy to paint and glue.

Prints in ABS plastic

✔Zeepro Zim 3D

The printer prints in ABS (acrylonitrile butadiene styrene). This is up to 30 times stronger than regular plastic and is commonly used in 3D printing.

Prints in PVA

✖Zeepro Zim 3D

Polyvinyl Acetate is another form of plastic used in 3d printing similar to ABS. It can be used to build support structures for other prints, as it can then be dissolved leaving no marks.

Prints in paper

✖Zeepro Zim 3D

The printer is able to print in paper. 3D printing in paper involves an additive process whereby a laser cuts each layer of paper into the correct shape to create the final model. Paper 3D printed objects have a similar consistency to wood.

Prints in wood

Technical Details

High repeatability

Lightning speed

1.
5 mm lifting distance Compatible with flexible filaments

Why is high repeatability good for a 3D printer? What does high reliability mean?

3D printing is a process where an object is built up by thin layers. The 3D printer needs to move back and forth along the length of the model to create those thin layers. If the printer loses its position during that back-and-forth motion, the 3D printing process will no longer be aligned, and the 3D printed object will be ruined. The high repeatability and reliability ensure the printer does not become misaligned during the back-and-forth movements.

 

What does lightning speed mean?

Lightning speed refers to the overall amount of time the 3D printer takes to print an object. However, this speed is heavily influenced by the type of project being printed and how quickly the printer can switch directions during the back-and-forth movement. Having a <1 second switch time means the Pro3 Series can change directions while printing an object. This shortens the overall time needed to complete a 3D printing process. Keep in mind, the general time savings will still be influenced by the project type.

 

Why is a 1.5 mm lifting distance beneficial to a 3D printer?

Lifting distance refers to the clearance between the idle printing nozzle and the object being printed. There needs to be some distance between both to ensure the printer’s nozzle does not interfere with the printing. The 1.5 mm lifting distance on the Pro3 Series maintains enough distance between the idle nozzle and the model to not affect the printing process.

 

User Friendly Features

 

Lightweight Cable with Digital Temperature Measurement

The Pro3 Series replaces the drag chain cable with a lightweight cable, to reduce the weight of the extruder and keep the center of gravity in the middle during printing for more stable print quality. The Pro3 Series also uses digital temperature measurement, for an accurate temperature reading to help prevent jamming.

The importance of Auto Bed Leveling

Bed leveling is the process of confirming that the printing platform is as level as possible. The Pro3 Series has this leveling procedure as an automated function. Auto bed leveling will maintain the distance between the print nozzles and the bed, to create a uniform build area. This improves bed adhesion and allows the nozzle to adjust to even the most minor surface contour changes.

Live Monitoring HD Camera

The Pro3 Series uses a HD camera to monitor the entire 3D printing process of every print job. This camera operates by connecting to RaiseCloud, allowing users to keep track of every print job remotely and while on the move. This ability to check the 3D printing process gives peace of mind. The Pro3 Series also comes with an upgraded CMOS sensor to ensure better image quality.

Safety Features

 

Power Loss Recovery

Either a power outage or a filament outage (when the filament runs out) can cause a print job to be lost if they occur in the middle of the 3D printing process. However, the Pro3 Series has a filament run-out sensor on its extruders to alert when the filament is about to run out and saves the print job. It also has a second-generation power loss function to save the printing status in the event of a power outage and can continue printing from the same point when power is restored.

Automatic Detection

Another safety feature of the Pro3 Series is that it can automatically detect when a door is opened and will immediately pause the print.

Material Compatibility Flexible Build Plate HEPA Air Filter Touch Screen & Software Monitoring Full Metal Frame

The Pro3 Series is compatible with a variety of 3D printing materials (known as filaments) to meet project requirements

Depending on the project goals, more than one 3D printing filament is necessary to accommodate varying structural or functional requirements (for example, some requirements may include flexibility, and strength). Sometimes multiple filaments are required within the same print job. Having a 3D printer that is compatible with different filament types is both cost-saving and practical for print jobs requiring multiple filaments, giving it extra versatility other printers cannot match.

Flexible build plate for easy removal of printed models

The Pro3 Series is equipped with flexible build plate. The flexible build plate can be used to easily remove printed parts while minimizing potential damage to the final print. Additionally, the flexible build plate can quickly regain its shape and return to printing quickly. The Pro3 Series is also compatible with a rigid build plate, as well as a high-temperature borosilicate glass build plate.

The updated HEPA air filtration removes toxic particles released during the 3D printing process

The Pro3 Series uses HEPA air filtration to clean the air of any particles (including nano-particles) released during the 3D printing process. The HEPA air filter works effectively in classrooms, offices, and in large and small workspaces and operates silently, quietly working in the background of any work area.

7-inch touch screen for efficiency and monitor the printing process with 3D printing software

The Pro3 Series’ 7-inch touch screens allow users to interact with the printer directly. It also provides on-screen assistance and visual model selections to simplify operating and monitoring both the 3D printer and 3D printing process. As with all Raise3D 3D printers, the Pro3 Series is compatible with ideaMaker, a 3D slicing program, and RaiseCloud, a cloud-based 3D printing management platform. This wireless connection allows users to keep track of every print job while on the move.

The full metal frame acts as a reliable motion system for smooth movement and precise positioning for higher quality printing

High-quality 3D printing comes from high-quality 3D printers. The Pro3 Series professional dual extruder 3D printer uses a full metal frame to create a specific motion system that allows the machine to smoothly glide as it prints. This motion system works with precise positioning to ensure 3D print jobs are as accurate as possible. Interchangeable nozzles allow the Pro3 to print at different levels of detail.

How metal 3D printers work. Overview of SLM and DMLS technologies. additive manufacturing. 3D metal printing.


Metal 3D printing. Additive technologies.

SLM or DMLS: what's the difference?

Hello everyone, Friends! 3DTool is with you!

BLT metal 3D printer catalog nine0003

Selective laser melting ( SLM ) and direct metal laser sintering ( DMLS ) are two additive manufacturing processes that belong to the family of 3D printing , using the powder layer method. The two technologies have much in common: they both use a laser to selectively melt (or melt) metal powder particles, bonding them together and creating a pattern layer by layer. In addition, the materials used in both processes are metals in granular form. nine0003

The differences between SLM and DMLS come down to the basics of the particle bonding process: SLM uses metal powders with a single melting point and completely melts the particles, while in DMLS the powder consists of materials with variable melting points.


Specifically:
SLM produces single metal parts while DMLS produces metal alloy parts.
Both SLM and DMLS technologies are used in industry to create final engineering products. In this article, we will use the term "metal 3D printing" to summarize the 2 technologies. We will also describe the main mechanisms of the manufacturing process that are necessary for engineers to understand the advantages and disadvantages of these technologies. nine0047 There are other manufacturing processes for producing dense metal parts, such as electron beam melting (EBM) and ultrasonic additive manufacturing (UAM). Their availability and distribution is rather limited, so they will not be presented in this article.

How metal 3D printing SLM or DMLS works.

How does metal 3D printing work? The basic manufacturing process for SLM and DMLS is very similar.

1. The printing chamber is first filled with an inert gas (such as argon) to minimize the oxidation of the metal powder. It then heats up to the optimum operating temperature. nine0047 2. A layer of powder is spread over the platform, a powerful laser makes passes along a predetermined trajectory in the program, fusing the metal particles together and creating the next layer.
3. When the sintering process is completed, the platform moves down 1 layer. Next, another thin layer of metal powder is applied. The process is repeated until the entire model is printed.

When the printing process is completed, the metal powder already has strong bonds in the structure. Unlike the SLS process, parts are attached to the platform via support structures. The support in metal 3D printing is created from the same material as the base part. This condition is necessary to reduce deformations that may occur due to high processing temperatures. nine0047 When the 3D printer's chamber cools down to room temperature, excess powder is removed manually, such as with a brush. The parts are then typically heat treated while they are still attached to the platform. This is done to relieve any residual stresses. They can then be further processed. The removal of the part from the platform occurs by means of sawing.

The scheme of the 3D printer for metal.

In SLM and DMLS, almost all process parameters are set by the manufacturer. The layer height used in metal 3D printing varies from 20 to 50 microns and depends on the properties of the metal powder (flow, particle size distribution, shape, etc.). nine0047 The basic size of the print area on metal 3D printers is 200 x 150 x 150 mm, but there are also larger sizes of the working area. Printing accuracy is from 50 - 100 microns. As of 2020, metal 3D printers start at $150,000. For example, our company offers 3D metal printers from BLT.
Metal 3D printers can be used for small batch production, but the 3D printing capabilities of such systems are more like those of mass production on FDM or SLA machines. nine0047 The metal powder in SLM and DMLS is recyclable: typically less than 5% is consumed. After each impression, the unused powder is collected and sieved, and then topped up with fresh material to the level required for the next production.
Waste in metal printing, are supports (support structures, without which it will not be possible to achieve a successful result). With too much support on the manufactured parts, the cost of the entire production will increase accordingly. nine0047

Adhesion between coats.


3D metal printing on BLT 3D printers

SLM and DMLS metal parts have almost isotropic mechanical and thermal properties. They are hard and have very little internal porosity (less than 0.2% in 3D printed condition and virtually non-existent after processing).
Metal printed parts have higher strength and hardness and are often more flexible than traditionally made parts. However, such metal becomes “tired” faster. nine0003

3D model support structure and part orientation on the work platform.

Support structures are always required when printing with metal, due to the very high processing temperatures. They are usually built using a lattice pattern.

Supports in metal 3D printing perform 3 functions:

• They form the basis for creating the first layer of the part.
• They secure the part to the platform and prevent it from deforming.
• They act as a heat sink, removing heat from the model. nine0003

Parts are often oriented at an angle. However, this will increase the amount of support required, the printing time, and ultimately the overall cost.
Deformation can also be minimized with laser sintering templates. This strategy prevents the accumulation of residual stresses in any particular direction and adds a characteristic surface texture to the part.

Since the cost of metal printing is very high, software simulations are often used to predict how a part will behave during processing. These topology optimization algorithms are otherwise used not only to increase mechanical performance and create lightweight parts, but also to minimize the need for supports and the likelihood of part distortion. nine0003

Hollow sections and lightweight structures.


An example of printing on a BLT 3D printer

Unlike polymer powder melt processes such as SLS, large hollow sections are not typically used in metal printing as the support would be very difficult to remove, if at all possible.
For internal channels larger than Ø 8 mm, it is recommended to use diamond or teardrop cross-sections instead of round ones, as they do not require the construction of supports. More detailed recommendations on the design of SLM and DMLS can be found in other articles on this topic. nine0003

As an alternative to hollow sections, parts can be made with sheath and cores, which in turn are machined using different laser power and pass speeds, resulting in different material properties. The use of sheath and cores is very useful when making parts with a large solid section, as it greatly reduces printing time and reduces the chance of warping.

The use of a lattice structure is a common strategy in metal 3D printing to reduce part weight. Topology optimization algorithms can also help design organic lightweight shapes. nine0003

Consumables for 3D metal printing.

SLM and DMLS technologies can produce parts from a wide range of metals and metal alloys, including aluminum, stainless steel, titanium, cobalt, chromium and inconel. These materials meet the needs of most industrial applications, from aerospace to medical applications. Precious metals such as gold, platinum, palladium and silver can also be processed, but their use is of a minor nature and is mainly limited to jewelry making. nine0003

The cost of metal powder is very high. For example, a kilogram of 316 stainless steel powder costs approximately $350-$450. For this reason, minimizing part volume and the need for supports is key to maintaining optimal manufacturing cost.
The main advantage of metal 3D printing is its compatibility with high-strength materials such as nickel or cobalt-chromium superalloys, which are very difficult to machine with traditional methods. Significant cost and time savings can be achieved by using metal 3D printing to create a near-clean shape part. Subsequently, such a part can be processed to a very high surface quality. nine0047

Metal post-processing.

Various post methods. treatments are used to improve the mechanical properties, accuracy and appearance of metal printed products.
Mandatory post-processing steps include the removal of loose powder and support structures, while heat treatment (heat annealing) is typically used to relieve residual stresses and improve the mechanical properties of the part.

CNC machining can be used for critical features (such as holes or threads). Sandblasting, plating, polishing, and micro-machining can improve the surface quality and fatigue strength of a metal printed part. nine0003

Advantages and disadvantages of metal 3D printing.
