3D Printing

You need a sample of your early-stage product to show at a board meeting. Or maybe you’re fairly confident you’ve got the right design on paper, and it’s time to make your first prototype. Or perhaps, before manufacturing your product you want to try a couple minor variances on the design. 3D printing is the solution for all these scenarios. You don’t want to manufacture your product until you’ve seen a prototype and are absolutely sure everything is right. Trust us. At Dinsmore, our selection of technologies is second to none.

After considering quantity, budget, intricacy, material and turn-around time, we’ll recommend one of the following:

SLA

SLA is our most frequently used process. Its hallmarks include precision, speed and affordability; the technique uses a liquid building process to create very fine details when the product hardens. It’s a truly customizable technology offering many choices for material, color and finish.

Available materials:

  • ProtoGen™ 18420
  • BioClear
  • 8120
  • NeXt
  • WaterShedXC

DLS

DLS, which stands for Digital Light Synthesis, eliminates some of the shortcomings that come from other 3D printing technology. DLS works by projecting a continuous sequence of UV light which is generated by a digital light projector through an oxygen-permeable, UV-transparent window below a liquid resin bath. The “dead zone” created above the window maintains a liquid interface below the object. Above the dead zone, the curing part is drawn out of the resin bath.

DLS can create objects up to 100 times faster than commercial 3D printing methods.

Available materials:

  • Elastomeric Polyurethane (EPU 40)
  • Rigid Polyurethane (RPU 70, RPU 60, RPU 61)
  • Prototyping Resin (PR 25)
  • Flexible Polyurethane (FPU 50)
  • Cyanate Ester (CE 221)
  • Urethane Methacrylate (UMA)
  • Epoxy (EPX 81)

FRSLA®

FRSLA® is a version of SLA specifically for products that are very small in size, or that feature extremely fine detail and need exceptionally high resolution. As the demand for quick-turn around on prototypes has grown, so has the demand for finer detail and higher quality models. Fine Resolution Sterolithography offers just that! Finer detail, quality, and speed.

SLS

SLS can create complex shapes in plastic, metal, ceramic or glass, and, based on the material used, can produce a very high-density product.

Available materials:

  • Nylon 12 AF
  • Nylon 12 GF
  • Nylon 12 PA
  • TPE 210- S

DMLS

DMLS is used strictly for metal products — including steel, chromium and titanium — and creates very complex shapes using a fiber optic laser. The ability to quickly produce a unique part is the most obvious because no special tooling is required and parts can be built in a matter of hours. Additionally, DMLS allows for more rigorous testing of prototypes.

Available materials:

  • Aluminum ASI 10M6
  • Cobalt Chrome MP1
  • Cobalt Chrome SP2
  • Digital ABS
  • Inconel 625
  • Inconel 718
  • Maraging Steel MS1
  • Stainless Steel 15-5
  • Stainless Steel 17-4

PolyJet

PolyJet also accommodates very complex shapes, but with a material that mimics rubber, with high flexibility. It offers some of the softest edges and smoothest finishes available.

Available materials:

  • Digital Materials
  • Digital ABS
  • Tango Materials (Elastomerics)
  • Vero Materials (Rigid Opaque)
  • Transparent Materials

FDM

FDM creates prototypes that can endure extreme climates, exposure to chemicals, and mechanical stress — this is for products that need exceptional durability and strength. It’s best for plastic products that feature fairly solid structures.

Available materials:

  • ABS-M30
  • Nylon
  • Polycarbonate
  • Polycarbonate-ABS
  • Ultem 9085
