How Does Metal 3D Printing Work?
The DMLS machine begins sintering each layer—first the support structures to the base plate, then the part itself—with a laser aimed onto a bed of metallic powder. After a cross-section layer of powder is micro-welded, the build platform shifts down and a recoater blade moves across the platform to deposit the next layer of powder into an inert build chamber. The process is repeated layer by layer until the build is complete.
When the build finishes, an initial brushing is manually administered to parts to remove a majority of loose powder, followed by the appropriate heat-treat cycle while still fixtured in the support systems to relieve any stresses. Parts are removed from the platform and support structures are removed from the parts, then finished with any needed bead blasting and deburring. Final DMLS parts are near 100 percent dense.

SLA Material Options
ABS-Like White (Accura Xtreme White 200)
ABS-Like White (Accura Xtreme White 200) is a widely used general purpose SLA material. In terms of flexibility and strength, this material falls between molded polypropylene and molded ABS, which makes it a good choice for functional prototypes. Parts as large as 29 in. x 25 in. x 21 in. can be built with ABS-Like White so consider it a primary option if you require an extensive part size build envelope.
Primary Benefits
- Durable, general purpose resin
- Accommodates extra-large parts
ABS-Like Gray (Accura Xtreme Gray)
ABS-Like Gray (Accura Xtreme Gray) is a widely used general purpose SLA material. In terms of flexibility and strength, this material falls between molded polypropylene and molded ABS, which makes it a good choice for functional prototypes. ABS-Like Gray offers the highest HDT of the ABS-like SLA resins.
Primary Benefits
- Durable, general purpose resin
- Highest HDT of the ABS-like SLA resins
ABS-Like Black (Accura 7820)
ABS-Like Black (Accura 7820) is a widely used general purpose material. Its deep black color and glossy up-facing surfaces in a top profile offer the appearance of a molded part, while layer lines may be visible in a side profile. RenShape 7820 also has low moisture absorption (0.25% per ASTM D570) so that parts are more dimensionally stable. Compared to other SLA materials, it has midrange values for all mechanical properties.
Primary Benefits
- Low moisture absorption
- Glossy cosmetic appearance
ABS-Like Translucent/Clear (WaterShed XC 11122)
ABS-Like Translucent/Clear (WaterShed XC 11122) offers a unique combination of low moisture absorption (0.35% 0.25% per ASTM D570) and near-colorless transparency. Secondary operations are required to achieve functional part clarity, and the part will also retain a very light blue hue afterward. While good for general-purpose applications, WaterShed is the best choice for flow-visualization models, light pipes, and lenses.
Primary Benefits
- Lowest moisture absorption of SLA resins
- Functional transparency
MicroFine™ (Gray and Green)
MicroFine™ is a custom formulated material available in gray and green that is exclusive to Protolabs. This ABS-like thermoset is printed in Protolabs’ customized machinery to achieve high resolution features as small as 0.002 in. MicroFine is ideal for small parts, generally less than 1 in. by 1 in. by 1 in. In terms of mechanical properties, MicroFine falls in the mid-range of SLA materials for tensile strength and modulus and on the low end for impact strength and elongation.
Primary Benefits
- Produces highest resolution parts
- Ideal for extra-small parts
PP-Like Translucent White (Somos 9120)
PP-Like Translucent White (Somos 9120) is the most flexible SLA option outside of Carbon RPU 70 and FPU 50. In direct comparison to the average values of an injection-molded polypropylene, 9120 has similar tensile strength, tensile modulus, flexural modulus, and impact strength. The only departure from molded PP is its elongation value, which is only 25% of the molded thermoplastic.
Primary Benefits
- Semi-flexible
- Translucency
PC-Like Advanced High Temp (Accura 5530)
PC-Like Advanced High Temp (Accura 5530) creates strong, stiff parts with high temperature resistance. A thermal post-cure option can increase HDT as high as 482°F at 0.46 MPa loading. Accura 5530 has the highest E-modulus of all the unfilled SLA materials, and it is known for being resistant to automotive fluids. However, the thermal curing process does make Accura 5530 less durable, resulting in a 50% reduction to elongation.
Primary Benefits
- High elastic modulus
- Higher resistance to heated fluids
PC-Like Translucent/Clear (Accura 60)
PC-Like Translucent/Clear (Accura 60) is an alternative to the general purpose ABS-like materials and WaterShed XC 11122 when stiffness is desired. Like WaterShed, this material can be custom finished to achieve functional transparency with secondary processing. Accura 60 has the highest tensile strength of and elastic modulus compared of all SLA materials outside of the Advanced High Temp options that are most often thermal cured.
Primary Benefits
- High stiffness
- Functional transparency
Ceramic-Like Advanced HighTemp (PerFORM)
Ceramic-Like Advanced HighTemp (PerFORM) exhibits the highest tensile strength and E-modulus making it the stiffest performance material of the SLA materials. When the thermal cure option is applied to parts made from PerFORM, it exhibits the highest HDT (as high as 514°F at 0.46 MPa loading) of the SLA materials.
Primary Benefits
- Stiffest SLA resin
- Highest HDT of SLA resins

Metal Plating
Our metal-plating process for SLA coats a ceramic-filled PC-like material (Somos PerFORM) with a nickel that gives parts the look, feel, and strength of metal, but without the weight. The combination of the material’s strength, rigidity, and temperature resistance with nickel plating, takes strength, stiffness, and impact and temperature resistance to a degree previously unattainable in SLA parts.
Microfluidics
Our microfluidic fabrication process is a modified form of high-resolution SLA that uses a clear ABS-like material (WaterShed XC 11122). Parts are resistance to water and humidity, and work well for lens and flow-visualization models.
Our SLA 3D Printers
Our stereolithography machines consists of Vipers, ProJets, and iPros. In high-resolution mode, Vipers and ProJets can make parts with extremely tiny features and crisp details, while in normal-resolution mode, they can build cost-effective parts very quickly.
iPros have extremely large build volumes at 29 in. by 25 in. by 21 in. (736mm by 635mm by 533mm), yet are still able to image highly detailed parts easily.
Why Use SLA?
Stereolithography (SLA) is an additive manufacturing process that can 3D print parts with small features, tight tolerance requirements, and smooth surface finishes.
How Does SLA 3D Printing Work?
The SLA machine begins drawing the layers of the support structures, followed by the part itself, with an ultraviolet laser aimed onto the surface of a liquid thermoset resin. After a layer is imaged on the resin surface, the build platform shifts down and a recoating bar moves across the platform to apply the next layer of resin. The process is repeated layer by layer until the build is complete.
Newly built parts are taken out of machine and into a lab where solvents are used to remove any additional resins. When the parts are completely clean, the support structures are manually removed. From there, parts undergo a UV-curing cycle to fully solidify the outer surface of the part. The final step in the SLA process is the application of any custom or customer-specified finishing. Parts built in SLA should be used with minimal UV and humidity exposure so they don’t degrade.

3D prototyping (3D prototyping)
What is 3D prototyping
This is the process of building a real physical object based on its digital model. Modeling is performed using specialized software, and the prototype itself is created on its basis, using 3D printing.
Applications
The technology is often used in the following industries:
- construction, architecture; nine0012
- electronics, instrumentation;
- mechanical engineering;
- aviation, space industry;
- medicine, dentistry;
- education;
- design, media.
Plastic samples are made for preliminary testing of the parameters and characteristics of industrial products, spare parts for equipment, etc. Another technology is needed for the production of discontinued parts. With its help, it is much easier to achieve any physical and mechanical properties and implement innovative ideas. nine0005
Species
There are three types of prototyping:
- Industrial - for production needs, reconstruction, repairs.
- Architectural - models of houses, premises and even cities.
- Transport - samples of all types of vehicles.
Demonstration layouts can be classified into a separate category.
What is prototyping like
Rapid prototyping is based on the creation of a product based on its digital 3D sample. To get the product, the 3D printing method is used: nine0005
- SLA
- FDM
- CJP
- MJM
With SLA, or laser stereolithography, the sequential construction of layers is carried out from liquid photopolymers. The material hardens under the influence of a laser beam. The technique allows you to accurately model a product of complex shape and large dimensions, to achieve its high strength. Samples are obtained as close as possible to the layout and do not need complex “finishing”.
FDM (Fusion Deposition Method) is used to achieve ultra-accurate digital image transmission. Molten thermoplastic is applied in layers along the layout outlines. The main advantages of the method are manufacturing accuracy, inexpensive consumables, budget equipment.
Color Jet Printing technology involves making a sample from gypsum powder and a binder. The material is glued together in layers, forming an object. The advantages of the method are speed, low price, the ability to "play" with colors and textures. It is used for the production of single copies and small batches. nine0005
In Multi Jet Modeling, products are printed from wax or photopolymer. Layers of material are sequentially applied to the 3D printer building platform through the printheads. The method allows you to simultaneously print several materials that differ in density and viscosity.
Stages of prototyping
- development of a model on a computer using specialized software;
- production of a master model using 3D printing technology; nine0012
- testing in accordance with the customer's goals;
- revision, correction when deficiencies are identified;
- launch of serial production.
3D modeling
It is performed using software for working with three-dimensional graphics.
The object is created on the basis of drawings, sketches, drawings, graphs and other sources of information that can provide information about the requirements for the order. The completed 3D digital object in .stl format is sent to the printing device. nine0005
Master model
With the help of a printer, a master model is obtained. This is an exact copy of the sample in 1:1 scale. The product can be used as a demonstration sample, as well as for the removal of molds, dies, and the production of castings. At this stage, possible flaws can be identified and corrected.
Testing
At the testing stage, compliance with the characteristics of the finished product is checked. Mass production begins only after confirming the correctness of the shapes, sizes, functionality, and other parameters that are determined by the purpose of the item being created. nine0005
Correction
Deficiencies identified during testing are eliminated during the final adjustment. Changes are made to the digital model, which will be used for mass production.
Prototyping
After completion of testing and refinement, the product is ready for replication. The ordered product is received in a short time, which allows customers to save time.
Sample requirements
The requirements for the sample depend on its purpose, scope. Its properties are taken into account in advance in computer 3D design. nine0005

3D printed prototypes for functional testing
Testing product prototypes, individual assemblies and parts is an essential part of any production chain. With 3D printing, you can quickly obtain high-precision and low-cost samples of future products for various tests and tests. nine0005
Which tests can you carry out on the received products:
- check the assembly for assembly;
- study the behavior of various materials in the working environment;
- test new design solutions;
- to check the strength, wear resistance;
- blow through objects in a wind tunnel.
