The Commonly Used Metal 3D Printing Materials

Metal 3D printing uses a variety of metal powders, wires, and even liquid resins infused with metal. Almost any metal can be 3D printed, from stainless steel to nickel-based alloys, and in practice, about 8 are most commonly used. The most common question about metal 3D printing is: Will the final part have the same mechanical properties as a machined, moulded or forged metal part? The answer is yes, and sometimes even better mechanical quality, but it depends a lot on the metal 3D printing technology you use, the type of feedstock used, post-processing and the shape of the part. In addition, the comparison depends on the aspects you are concerned about: for example, tensile strength, static load strength, high cycle fatigue, and so on.

In general, the material properties of metal parts made by metal bond jetting are equivalent to those of metal parts produced by metal injection moulding, and it is one of the most widely used manufacturing methods for the mass production of metal parts. These 8 metal alloys below are just the beginning of what is possible today as metal material producers continue to push the boundaries and customize metal alloys for specific needs using specific metal 3D printing technologies.

1.Stainless Steel Feature: All-round Stainless steel is not the material most commonly used in 3D printing, but many alloy varieties. The first two are 316L and 17-4 PH, but also 304L, 15-5 PH, 420, 254, PH1, GP1, 630, and 410 can be printed, as well as custom blends produced by material manufacturer. These steels are specifically designed to resist corrosion. They are a lightweight and affordable metal that is ideal for 3D printing. This is because it is faster and cheaper than traditional methods and can print small batches and complex parts. 3D printing is the preferred option for companies that need a single tool or several replacement parts. Stainless steel can be used in almost any type of 3D printing, from economical wire for extruded 3D printing on benchtop machines to powder for binder jetting and laser powder bed fusion, and even resin.

2.Tool Steel Feature: High hardness, good wear resistance Tool steels, like stainless steels, come in different varieties with different tensile strengths, ductility, hardness and other properties. Tool steels are a variety of alloy steels designed specifically for the manufacture of tools. They are known for their hardness, wear resistance and ability to hold a cutting edge at high temperatures. This 3D printing steel is commonly used in the manufacture of injection mould inserts, aerospace components, military applications, manufacturing tools, as well as construction and architecture. The main advantage of 3D printed tool steel is not only its strength, but also its unique ability to create parts with internal channels (e.g. cooling channels in moulding tools) and lattice fillings that cannot be manufactured by traditional methods.

3.Low-Alloy Steel All 3D printing steels are alloys, but this category includes steels with low or less than 5 per cent of other elements. These low alloy steels are designed to have higher mechanical properties and greater resistance to wear and corrosion than other steels which are commonly used in automotive, aerospace and structural applications.

4.Aluminum Feature: Lightweight and corrosion resistant For aerospace, automotive and industry, the design freedom and cost efficiency of 3D printing further enhances the lightweight and chemical resistance of aluminum components. The use of aluminum and aluminum alloys in 3D printing is surging because the metal is economical and easy to 3D print. Like most metals, aluminum can be used as wire or powder for a variety of 3D printing techniques. Aluminium has good chemical resistance, is very light and has one of the best strength-to-weight ratios of any metal. Combined with silicon and magnesium, it is the choice of many in the aerospace and automotive industries because of its ability to withstand harsh conditions.

5.Titanium Feature: Lightweight and biocompatible As strong as steel but half the weight, titanium is a complex metal that is practically made for 3D printing. Titanium has become one of the most commonly used metals in additive manufacturing, with a wide range of applications in aerospace, joint replacement and surgical tools, racing car and bicycle frames, electronics and other high-performance products. Titanium and titanium-based alloys offer high mechanical strength, high strength-to-weight ratios and better corrosion resistance than stainless steel. It makes rockets and aircraft lighter, thus saving fuel and increasing payload capacity. In the medical industry, 3D printed titanium implants have been successfully used in the spine, hips, knees and extremities due to the inherent biocompatibility and good mechanical properties of the metal, coupled with the ability to customize porous structures with 3D printing, allowing for osseointegration and mass customization for better patient outcomes.

6.Copper Feature: Electrical and thermal conductivity 3D printing using pure copper and space-age copper alloys is available with a range of metal 3D printers and services. You can create rapid copper prototypes using copper filament on an FDM 3D printer and large copper rocket boosters using copper alloys on a laser powder bed fusion 3D printer. There is also copper wire and copper resin for micro 3D printing. In fact, copper plays a huge role in the global sustainable development goals as a key component of electric motors, charging infrastructure, solar energy and batteries.

7.Nickel Alloy Feature: Extreme environments resistant Nickel-based alloys and "high-temperature alloys" are known for their excellent high-temperature strength, corrosion and oxidation resistance. These alloys retain their strength and mechanical properties at high temperatures. They are commonly used in demanding applications such as aerospace, gas turbines, chemical processing and marine environments. In recent years, these alloys have also become increasingly popular in 3D printing, especially in the aerospace and automotive industries. When referring to nickel alloys, you may hear the term inconel. Inconel is the trade name for a range of nickel-chromium-based high-temperature alloys, including IN625, IN718 and IN939. Nickel alloys are generally more expensive than other materials such as steel and aluminium and may not be suitable for low temperature applications.

8.Cobalt Chrome Feature: High temperature and corrosion resistance 3D printed cobalt chrome has a high strength-to-weight ratio and excellent corrosion resistance, making it a good material choice for aerospace components and industrial machinery. It is also biocompatible and is often used in orthopaedic implants, dental prosthetics and medical devices that require long-term contact with biological tissue. Cobalt-chromium alloys can be processed using additive manufacturing techniques such as selective laser melting (SLM) or electron beam melting (EBM). This allows complex geometries and customized parts to be produced with minimal material waste, making it attractive to industries adopting advanced manufacturing techniques.

To sum up, metal 3D printing uses a wide range of metal powders and wires, including stainless steel, tool steel, etc. to print complex parts with superior mechanical properties. Commonly used metals in 3D printing include aluminum, titanium, copper, nickel alloys, tool steel, cobalt-chromium alloys, stainless steel for aerospace, medical and jewellery applications and more.

I wanna see the necklace omg! That’s so cool of y’all

THANK YOU FOR ENABLING ME you are my favorite

we used to have a silver otherkin star that we wore daily, but the top fixture snapped. rather than replace it, we figured the plural rings were a little more accurate for us now, anyway.

a friend ended up doing the model (albeit while we sat behind and gave feedback), we paid shapeways for the printing, for speed & just to save us the trouble of actually producing something to "daily wear" standards. would recommend.

SLS vs. SLA 3D Printing Unveiling the Best Option

SLS 3D printing, or Selective Laser Sintering, is an additive manufacturing process that utilizes a high-powered laser to fuse small particles of powdered material together, layer by layer, to create three-dimensional objects. This technique is renowned for its versatility and ability to produce complex geometries with high precision.

What's The Differences Between SLA and SLS in Rapid Prototyping?

Rapid Prototyping(RP) is a manufacturing technology that quickly generates models or parts. There are more than ten different processes, such as stereolithography (SLA), laminated object manufacturing (LOM), selective laser sintering (SLS), fused deposition modeling (FDM), solid ground curing (SGC), three dimensional printing (3DP_Binder Jetting), ballistic particle manufacturing (BPM), etc. Among them, SLA is the earliest and most widely used technology, accounting for about 70% of all rapid prototyping equipment.

Today we'll discuss the differences between SLA and SLS from four aspects.

The principle of SLA: use laser of a specific wavelength to solidify the resin.

The material of SLA is the category of resin.

The characteristics of SLA:

1. Stereolithography is the earliest rapid prototyping process, with high maturity and time-tested. 2. The prototype is made directly from the CAD digital model, with fast processing speed, short production cycle, and no need for cutting tools and molds. 3. It can process prototypes and molds with complex structures or difficult to form using traditional means. 4. Make CAD digital models intuitive and reduce the cost of error repair. 5. Provide samples for experiments can verify and check the results of computer simulation calculations. 6. It can be operated online and remotely controlled, which is conducive to production automation.

The disadvantages of SLA:

1. The SLA system is expensive to build, use and maintain. 2. The SLA system is a precision device that operates liquids and has strict requirements on the working environment. 3. Most molded parts are made of resin, which has limited strength, rigidity and heat resistance, and is not conducive to long-term storage.

The principle of SLS: heat the powder sintered to near melting point of the material and then add laser energy to sinter it.

The material of SLS is nylon and various materials and mixed materials.

The characteristics of SLS:

1. A variety of materials can be used. In principle, this method can use any powder material that reduces viscosity when heated, and can produce any shape through materials or various types of coated particles containing binders to meet different needs. 2. The manufacturing process is relatively simple. Since a variety of materials can be used, the selective laser sintering process can directly produce complex-shaped prototypes, cavity mold three-dimensional components or parts and tools according to the raw materials used. 3. No support structure is required. The overhanging layers that appear during the lamination process can be supported directly by the unsintered powder. 4. High material utilization rate. Since the process does not require a support structure, most of the powders used in the SLS process are relatively cheap, so the cost of the SLS model is relatively low. 5. Short production cycle. It only takes a few hours to dozens of hours from CAD design to the completion of parts processing. The entire production process is digitalized and can be modified and manufactured at any time. This feature makes it particularly suitable for the development of new products. 6. Combined with traditional process methods, it can realize functions such as rapid die casting, rapid molding and small batch manufacturing, injecting new vitality into traditional manufacturing methods. 7. Wide application. Due to the diversity of molding materials, the SLS process is suitable for a variety of application fields, such as prototype design verification, mold master, precision casting investment, casting shell and core, etc.

The disadvantages of SLS:

1. Rough surface. Since the raw material of SLS process are in powder form, the prototype is built by melting the powder layer by layer through heating. Therefore, strictly speaking, the surface quality of the prototype is not good enough as in powder form. 2. Polymer materials or powder particles generally emit odorous gases during laser sintering and melting. 3. Sometimes more complicated auxiliary processes are required. SLS technology varies depending on the materials used, and sometimes more complicated auxiliary processes are required, such as preheating the raw materials for a long time, cleaning the surface powder of the model after the modeling is completed, etc.

The advantage of RP prototype is its rapidity, but it is mainly formed by stacking technology, so RP prototype is generally relatively rough, and has centain requirements on the wall thickness of the product. For example, if the wall thickness is too thin, it cannot be produced.

I have the right to refuse any offer for any reason!

We will ofc talk about your wishes & ideas, and depending on what you want in the end, prices might even be able to change a bit (for example, if you want to have something in between a half-body and a portrait... such things).

PAYMENT taken 50% upfront, and when I show you the lineart and you are okay with it, I'll take the other 50% and then continue working on your art. NO REFUNDS. You are allowed a total of 3 revisits / changes of the lineart, and I will only be able to change simple things on your artwork when fully colored (e.g. change a color to another color). You are not allowed to use my art for commerical purposes / AI training / any of that bullshit. PRIVATE USE ONLY.

PAYMENT VIA PAYPAL INVOICE OR KO-FI ONLY.
