3D Scanning (Laser & Structured Light) F.A.Q.
3D Printer F.A.Q.
|3D Printer||Dimension SST 1200|
ABS acrylonitrile butadiene styrene (chemical formula (C8H8)x'(C4H6)y'C3H3N)z) is a common, strong, durable production-grade thermoplastic used across many industries.
ABS is an ideal material for conceptual prototyping through design verification through direct digital manufacturing. This material is ideal for the rapid production of prototypes, tooling and the direct (tool-less) manufacturing of production parts.
ABS is widely used in applications where impact-resistance and structural strength are necessary. It is accurate, durable and robust enough for field testing or demonstration units. Because of its excellent dimensional stability, it is ideal for pre-production rapid prototypes that can accurately predict performance of injection molded parts.

|Layer Thickness:||254 mm (.010 in.) or .33 mm. (.013 in.) of precisely deposited ABS model and support material.|

Based on the patented Stratasys FDM®, Dimension builds functional 3D models from the bottom up, one layer at a time of with tough, ABS plastic. STL files are imported into CatalystEX® software which automatically slices and orients the parts and creates any necessary support structures. The software automatically plots a precise deposition path for Dimension to follow. ABS plastic (in filament form within auto-loading cartridges) is fed into an extrusion head, heated to a semi-liquid state and accurately deposited in layers as fine as 0.010-inch (0.254 mm) thick. After completion of the build, support structures are simply removed.
ABS plastic is heated to a semi-liquid state and deposited in thin layers by a patented extrusion head.
Catalsyt software automatically determines when and where to deposit ABS or support material throughout the build process.
3D SLA (Stereolithography) Printing F.A.Q.
|generic 3D SLA (Stereolithography) Printing|
Stereolithography, the technology behind most resin 3D prints, is often referred to as ‘the mother of all 3D printing technologies’ and is considered one of the most widely used techniques for producing high-quality 3D prints. Stereolithography printers work with razor-thin layers of liquid polymer that are cured by a computer-controlled UV laser which transforms the resin from a liquid to a solid state.

3D Printer Input File Formats
3D Parametric (Modeling / Reverse Engineering) F.A.Q.
|Basic Scan Data Outputs|
|Point Cloud (.asc, .txt):||Point Cloud data is often the most basic scan data output, and mostly used for downstream applications. This data is not easily imported into most CAD/CAM packages.|
|Polymesh (.stl)||A conversion from the point cloud into a triangulated surface mesh. In special cases a polymesh file can be used directly for 3D printing or machining of organic shapes.|
|CAD Modeling Outputs|
|Surface (NURBS) Model (.igs, .stp)||A freeform CAD model defined by spline-based surfaces (NURBS). These models only match the as-built state of the part and are ideal for curvature, but not sharp features.|
|Solid Model (.igs, .stp, .x_t, .x_b)||A feature-based CAD model without a design history. These models can either incorporate or fix manufacturing defects and are ideal for prismatic shapes and sharp edges.|
|Hybrid Model (.igs, .stp)||A combination of imported surfaces and CAD features. These models are ideal for parts with a mixture of prismatic features and complex curvature or organic geometry. Parametric Model (Solidworks, Pro/E, Catia, etc.) The ultimate CAD model that maximizes editability and performance by incorporating a design history tree and dimensioning. Ideal for when changes to the model are needed.|
|Organized Polymesh (.stl, .obj, .ply)||A conversion from a CAD model to a polymesh. The size and spacing of the triangles are organized, resulting in a higher quality mesh that is ideal for rendering and animation.|
|Class A Surface Model (.igs, .stp)||Typically a Surface Model whose surfaces are all curvature-continuous and tangent. This is important to allow for an ideal aesthetic look and feel, especially in reflections.|
|Block Model (.igs, .stp)||A block model can be created in situations where the level of detail is not a high priority. For example, the wheels in a car assembly can be cylinders for location and reference.|
Clean & Optimized Polygon Mesh / Point Cloud -
Data is processed from single or multiple scans. Geometry is represented by a mesh of triangles Holes have been filled, defects removed, rough spots smoothed. Suitable for CNC machining, rapid prototyping, 3D printing or further processing into a surface or solid model.
File Format: stl
Cross-Sectional Curves -
Network of curves developed by slicing through a point cloud or polygonal mesh. Geometry is represented by splines. Useful for import into CAD to develop 2D drawings or 3D models.
File Format: iges
Rapid Surface Model -
Quilt of smooth surface patches is "shrink-wrapped" onto the polygonal mesh to create a model suitable for import into CAD. Upon CAD import, surfaces are knit together to form a static, or non-parametric solid. Useful for highly complex shapes such as organic forms, art & sculpture or intricate castings.
File Format: iges, step, Solidworks (sldprt)
Feature Based Solid Model -
Model is composed of primitive geometric features, trimmed surfaces, fillets & radii. Geometry is developed using traditional solid modeling techniques such as sketching and extruding, using the underlying scanned data as a reference. Original feature geometry may be extracted after import into customer CAD system.
File Format: iges, step, parasolid, Solidworks (sldprt)
Parametric Solid Model -
Model is composed of primitive geometric features, trimmed surfaces, fillets & radii. Geometry is developed using traditional solid modeling techniques such as sketching and extruding, using the underlying scanned data as a reference. Entire model history is transferred into Solidworks upon completion in order to facilitate future design changes.
File Format: Solidworks (sldprt)
|G0 (Positional continuity)||
Holds whenever the end positions of two curves or surfaces are coincidental.
The curves or surfaces may still meet at an angle, giving rise to a sharp
corner or edge and causing broken highlights.
|G1 (Tangential continuity)||
Requires the end vectors of the curves or surfaces to be parallel, ruling out
sharp edges. Because highlights falling on a tangentially continuous edge are
always continuous and thus look natural, this level of continuity can often be sufficient.
|G2 (Curvature continuity)||
Further requires the end vectors to be of the same length and rate of length change.
Highlights falling on a curvature-continuous edge do not display any change,
causing the two surfaces to appear as one. This can be visually recognized as
"perfectly smooth". This level of continuity is very useful in the creation of models
that require many bi-cubic patches composing one continuous surface.
