Polyjet Systems

Stratasys Objet Connex 260 Polyjet Printer, Stratasys Objet Eden 260 Polyjet Printer

Materials: Type: Proprietary acrylate based polymer. Rigid White & Flexible Translucent (which can be combined to achieve intermediate mechanical properties).  Alternatively, Rigid Translucent/Clear (Clear achieved with polishing)
Properties:
Variable mechanical properties but moderately low yield stress at highest stiffness. Behaves much like standard acrylic, unless blended with flexible material.  Alternative materials can be rubber-like in mechanical properties, or clear/translucent.

Accuracy: Extremely high: 16/32 micron layer thickness, Overall 0.05mm to 0.15 mm accuracy (depending on geometry).  Smallest free-standing feature approximately 0.25mm to 0.3mm Support Structures:  Gel-Like secondary material (Removed with water jet).  

Maximum Build Dimensions: 10.2×10.2×7.9 inches (260x260x200 mm)(Both Systems, single or multimaterial)

Build Time: Total: 30 minutes – 5+ Hours (dependent on geometry & size)
*Turnaround time is workload dependent.  Expedited parts may come with an additional fee.

Cost: UC: (at cost) Standard Material (Rigid and Flexible):  $5/10 grams of build material + $3/10 grams of support material + $3/hr of build time + setup and cleaning fee. Clear Material:  $7/10 grams of build material + $4/10 grams of support material + $3/hr of build time + setup and cleaning fee. Outside UC: 32% Premium (above cost)

Pros: Extreme accuracy, Parts can be printed as functional assemblies, functional prototypes (or direct application in light-duty).  Variable mechanical properties.  Near limitless geometric configurations

Cons: Material (generally) not as strong as FDM, or SLA techniques. Cost is comparatively higher than FDM or SLA.

FDM Systems

Raise3D N2, Raise3D N2 Plus, MakerBot Modified/Custom Replicator II, Markforged Mark Two Onyx

Materials: Type: ABS Plastic, PLA, other thermoplastics Properties: ABS –  Very High Yield Stress, standard engineering plastic. PLA – Plant derived plastic; Biodegradable. more rigid, more accurate than ABS.

Accuracy: Moderate/Good accuracy: 0.1mm minimum layer thickness (0.2mm standard), Overall 0.2-0.4mm accuracy depending on geometry. Smallest free-standing feature approximately 0.4mm Support Structures: Same Material, or overhang structures where possible

Maximum Build Dimensions12x12x24 inches (305x305x610 mm) – Raise3D N2 Plus, 12x12x12 inches (305x305x305 mm) – Raise 3D N2, 11.2×6.0×6.1 inches (285x153x155mm) – MakerBot

Build Time: Total: 15 minutes to 24+ Hours (dependent on geometry & size)
*Turnaround time is workload dependent.  Expedited parts may come with an additional fee.

Cost: UC: Black or White ABS or PLA: $4/10 Grams + $3/hr of build time + Setup and CleaningOutside UC: 32% Premium (above cost)

Pros: High impact resistance, good accuracy. Less Expensive.

Cons: Least accurate technique (visible layers), some geometry may not be printable.

SLA System

Overview of SLA Printing:

SLA 3D Printing is a technique whereby an object is etched into UV-curing liquid resin via laser, in a series of layers.   This printing technology is good where strength and good accuracy are both important characteristics, or where geometry may be too complex to achieve via FDM printing.  In general, this printing technology may not be appropriate where wall thicknesses exceed ~10mm, or with large-scale parts.

Our Machine: Formlabs Form 2 with automated Form Wash and Form Cure stations.

Materials: Type: Methacylate Photopolymer Resin Properties: (Similar to ABS) Higher yield point than Polyjet Prints.*Contact for Mechanical Properties

Accuracy: Good accuracy: 0.025mm to .1mm Layer Thickness.  0.1-0.3mm Overall Accuracy depending on geometry.  Minimum Feature 0.3mm.Support Structures: Posts which must be cut from body of printed part

Maximum Build Dimensions4.9×4.9×6.5 inches (125x125x165 mm)

Build TimeTotal: 4 hours to 24+ Hours (dependent on geometry & size)
*Turnaround time is workload dependent.  Expedited parts may come with an additional fee.

CostUC: Photo-Curing Resin: $4/10 Grams + $3/hr of build time + Setup and CleaningOutside UC: 32% Premium (above cost)

ProsVery rigid plastic with good impact resistance, great accuracy.

ConsSupport Posts may leave blemishes,  small build chamber
