How 3D printing work

3D printing or additive manufacturing is a process of creating a three-dimensional object by adding material layer by layer until the object is complete. It contrasts with traditional manufacturing techniques such as CNC machiningDie casting and Injection molding, it enables you to rapidly produces complex parts of nearly any shape. We can use digital CAD models to build physical, layered and real parts, select appropriate 3D printing technology on parts application. For your special products requirement, Runsom will select perfect 3D printing process and material for your projects.

3D Printing Application

Our 3D Printing is commonly used in many industries for rapid prototyping and  production: aerospace, automotive, consumer products, industrial products like special machinery, healthcare and medical, and architecture and construction industries.

3D Printing Advantages

1.Rapid Turnaround:3D printers can reduce the time frame of production. You can expedite your product development with 3D printing solutions that improve efficiencies.

2.Accuracy:3D prototypes are built with precision. Tight tolerances are an expectation for nearly every prototype, and 3D printers reduce the possibility of production errors. Your 3D printed prototype will provide an accurate representation you can use to better plan a final product.

3.Versatility:Current 3D printers use a variety of methods to print with a wide range of materials. This enables customers to experiment with different printing processes and materials to choose the best solution for their application.

4.Complexity:3D printing enables our team to produce 2D and 3D parts of almost any complex geometry. This makes it possible to create more intricate and accurate prototypes at a lower cost.

3D Printing Processes

Runsom Precision offers four 3D printing processes so whether you are making prototypes or production parts, you can find one that meets your needs.

Stereo Lithography Apparatus (SLA)

SLA use an ultraviolet laser system to interact photochemical process, link and form polymers together layer by layer. Then make up three-dimensional solid structure. SLA is very suitable for extremely accuracy and high resolution parts with injection mold-like, smooth surface finish and feature detail. SLA is also an additive manufacturing process that ultraviolet laser system bond photopolymer resin. It will provide higher resolution printing than other 3D technologies, customers can print parts with fine details and surface finishes. SLA 3D printing is highly-versatile platform for parts prototyping and production settings.

Selective Laser Sintering(SLS)

SLS use power source of laser to agglomerate powdered materials, bond materials together and create a solid structure by 3D model in space. SLS is used to produce functional plastic parts with good mechanical properties and high accurate. All these parts are capable for end-use, low volume production and rapid prototyping. SLS is an additive manufacturing layer technology, normally use high power laser (carbon dioxide laser) to fuse small plastic power into a designed 3D shape. The laser scans cross-sections by 3D digital description form CAD file or scan data, then selectively fuses powered materials form power bed surface. After that, a new material layer will be applies on top, and repeat this process until desired part is completed.

Fused Deposition Modeling (FDM)

FDM is widely know as high speed, high accuracy and competitive cost 3D technology. Printing machine extrudes precise melted plastic filament to create rigid parts, especially for projects with rigidity requirement. We always use FDM for low-cost prototyping and design verification with short turn around time. Runsom provides various color and thermoplastic material selection for customer requirement.

Binder Jetting

Binder Jetting is a professional additive manufacturing process, in this process, the binder materials is deposited on powder bed selectively, in order to bond these powder area together and form a solid layer at one time. The powder materials commonly used in Binder Jetting are metal, and ceramics. Binder Jetting is applied in various applications, including full color prototypes, low cost metal parts. We should understand the basic mechanic of this process with key benefits and limitations, in order to fully apply its capacities.

MultiJet Fusion(MJF)

MJF starts with powdered materials thin layer deposit on platform, fusing droplets mixing with detailing agents are applied with thermal energy on materials top to define parts geometry. MJF is used for small-batch plastic parts production with various function.

Direct Metal Laser Sintering(DMLS)

DMLS uses a fiber laser system to weld metal powder into fully dense metal parts by drawing atomized metal powder surface.DMLS is used to produce high-performance metal 3D printed parts for aerospace, medical and automotive industries. DMLS machine can produce high complex features and all-in-one assembly metal parts which is difficult to achieve with subtractive manufacturing techniques.

Each 3D printer has its specific advantages; please consult us to decide which 3D printing technology best meets your needs.

3D Printing Materials

Materials for 3D printing process must be suited to application for successful results. Properties of any materials important in producing process form concept and functional prototyping to production.

The right materials is very important in 3D printing process, cooperate with our additive manufacturing technologies, Runsom provides a wide dynamic range of materials. In order to satisfy various application requirements through products development cycle. We can meet customers critical time and cost-sensitive need with complex geometries from concept modeling to functional end-use parts.

SLA

Runsom specify details on SLA design to avoid unintended failures.
Wall thickness: we recommend minimum thickness of 1mm, this will reduce parts damage risk in post-process.
Holes & Gaps: Runsom recommend minimum diameter of 0.75mm, in order to retain shape and avoid close off in printing process.
Embossing: we recommend minimum protruding text must be 0.3mm in height and 0.4mm in width, in addition, high resolution option will be need for fine text details.
Engraving: engraving features should be large enough to avoid fusing together in printing process, so we recommend minimum size of engraved text must be 0.5mm wide and 0.4mm deep.
For more information of SLS design, check Runsom SLA design guide.

SLS

Design work in SLS is an interactive process, CAD need to be edited several time to optimize in process. Runsom team will work with you to design every feature correctly.
Wall thickness: we recommend at least 0.7mm wall thickness, thinner than 0.5mm wall will be significant deviation. In general, avoid deformation of variable thickness walls due to shrinkage and stress.
Gaps: Avoid over sintering by ensure thinner walls contain gaps.
Holes: reduce wall thickness on which hole is placed in order to make material clear convenient and reduce shrinkage.
Font size: compensate engraved letters with larger thickness and depth in order to increase acceptability.
Pins: avoid small pins too fragile to break off in post-processing.
For more information of SLS design, check Runsom SLS design guide.

FDM

FDM need support soluble or discrete materials for certain features, so we need to consider support structures to be removed in post-process in parts design.
Wall thickness: In support structure, minimum wall size must be at least 1.2-1.5mm in order to allow filament fill space between layers. Circular walls with thinner size are closer to design intent than straight walls.
Holes: Runsom recommend minimum FDM holes is 1mm in circular shape, hole orientation must be parallel to XY axis. Post-process drilling is only suitable for solid infill parts.
Text & Small details: Our recommended thickness of protruding text must be 1mm, in order to avoid unexpected errors, we suggest 1.2-1.5mm.
Gaps: Thin gaps should be wider than 5mm to make all support materials removed conveniently.

For more information of SLS design, check Runsom FDM design guide.

DMLS

In DMLS design, we should reduce need of support structures and removal, design parts is better to be self-supported. In addition, leverage mesh and lattice structure should be used to reduce material usage.
Wall thickness: minimum size is 1mm, lower than this size must be with height-to-thickness ratio less than 40:1.
Channels: circular channel diameter must be less than 8mm, all channels design should be self-supporting.
Text detail: for best resolution, text should be 0.4mm deep.
Self-supporting: self-supported angle should be larger than 45 degrees.
Lattice structures: lattice or mesh structure angle should be larger than45 degrees, and bridge distance need to be less than 2mm.
For more information of DMLS design, check Runsom DMLS design guide.

MJF

Most SLS design principles are relevant to MJF:
Wall: thin and large wall should be re-forced with ribs, guests or holes. Perfect wall thickness si 2.5 to 12.7mm.
Text details: minimum size of text or cosmetic features is 0.5mm
For more information of MJF design, check Runsom MJF design guide.

Binder Jetting

In Binder Jetting design, we should reduce need of support structures and removal, design parts is better to be self-supported. In addition, leverage mesh and lattice structure should be used to reduce material usage.
Wall thickness: minimum size is 0.2 mm, lower than this size must be with height-to-thickness ratio less than 40:1.
