Metal 3D additive manufacturing technology is fundamentally different from traditional subtractive manufacturing (such as machining). It is based on the principle of discrete stacking, where metal powders or wires are layered according to three-dimensional model data, ultimately constructing complete solid metal parts. This entire process does not require complex molds; instead, it allows for the rapid manufacture of complex-shaped metal components simply by inputting digital models, significantly breaking through the limitations of traditional manufacturing processes.
Metal 3D printing can easily produce intricate internal geometries, porous structures, and lattice designs that are challenging for traditional processes. For example, in the aerospace sector, fuel nozzles for engines can be designed with more efficient internal flow channel structures, enhancing fuel atomization and improving engine performance.
There’s no need to wait for mold fabrication; the time from design to prototype and then to final production is greatly reduced. In the new product development phase, designers can quickly validate their ideas, accelerating product iteration.
Designs can be flexibly adjusted according to customer needs, enabling the manufacture of personalized products. In the medical field, customized metal implants can be created based on a patient’s bone CT data, ensuring better compatibility and recovery outcomes.
The layer-by-layer stacking process generates almost no waste, allowing for a significant increase in material utilization compared to traditional machining methods, effectively reducing production costs and resource waste.

| Full Name | Selective Laser Melting | Electron Beam Melting | Selective Laser Sintering |
| Types | This technique uses a high-energy laser beam to selectively melt layers of metal powder, building parts layer by layer. SLM achieves high printing precision and surface quality and is suitable for various metals like titanium alloys, aluminum alloys, and stainless steel. It is commonly used for high-precision components in aerospace and medical fields. | EBM utilizes an electron beam as a heat source to melt metal powder in a high vacuum environment. The high energy density of the electron beam allows for fast processing speeds, making it suitable for manufacturing difficult-to-melt metal parts such as titanium and nickel-based alloys, especially in large metal structures for aerospace applications. | This additive manufacturing technology is based on powder bed fusion, where a high-energy laser beam sinters powder materials layer by layer to achieve three-dimensional forming. The process involves importing a 3D model into slicing software to convert it into layered two-dimensional data. The machine evenly spreads a layer of powder (usually 50-150μm thick) using a roller. The laser beam selectively scans the powder layer according to the sliced contour information, melting or binding the powder particles to form a layer of the part's cross-section. Unfused powder remains in the chamber as support, and the chamber lowers by one layer thickness, repeating the powder spreading and scanning process until the part is fully formed. This technology does not require support structures, and unfused powder can be reused, achieving a material utilization rate of over 95%. |

Hello，
I came across your company's machining information in Google and was interested in it.
I would like to ask you for the production of two components:
There are tno rollers dhaneter hmny with a kmrled suface n the miode. It is inportant that the kmwrls ot the rolers do not toupn each othar wmhan
the outer tlanks rum against eaclother. The distance between the two knurled surfaces should be about 0.1 mm.
The kmurled surface should not be too fine but not too coarse either. Do you have any examples?One roller has a pin (diametex 7.95m) and an
internal thread i8 (depth 20mn). The other roller has a through hole with a diameter of 8.05mmThe material is stainless steel, it should be suitable
for food.
May I ask you how much it would cost with shipping and when you could deliver it to Switzerland (Europe)?
For now it's just these two pieces, but can you also tell me how much it would cost if I order 2, 5, or 10 of each piece?
Thank your for offer with and without transport if possible.
Best Regards
They are looking good.
Thanks!
3D printed both plastic and aluminium (metal) parts, working with Nancy Li who was very professional andkept me updated with progress and quality. Tapped threads were added to some of the 3D printed parts (after printing), which worked out very well. Everything was very well packaged and the overall production time was quite fast. 3D printing of both metal and plastic was quite accurate. 3D printing metal does have some slight warping/deforming issues depending on the shape, but Nancy checked that with me for one of my parts which worked out Ok. Small 3mm holes were a bit smaller than expected, but easily drilled out onceI recieved them - possibly a tolerance issue with 3D printing. Overall extremely happy with the quality and process.Would definitely work with this company aqain.
Hello，
I have received the frame.
Its quality is perfect! Thank you.
I modified the drawing and want to order another sample.
I need to make some text on the visible side of the frame. What kind of methods of
rendereng/engraving of the text could you suggest?
Couldyouprovidemewithsomephotosofthedifferentkindsoftextonthepartsas
an idea examples?
Hi Sylvia，
We first try to get a good price in the Netherlands.
The best way seems to order the most parts via 247 steel , we are stillooking for a welder !
I let you know later this week.
NB thanks for the other aluminium products; they look great and fit well together !
With best regards.
Hi Mike，
Give your QC my thanks, great catch!
I have updated the drawing to match the 3D CAD.
The parts you made should be good to go.
Best,
Ricky
Hi, Melody
I have received your offer and the price is acceptable after our group discussion.
However, due to our first cooperation, l stll decide to place a sample order in your company first, when we get the sample to confirm thecorrectness,we can consider the bulk order.
One more thing, please give me some pictures of the part during the production process so that l wiluse to add to the product productioninformation, thanks!
Best wishes!
