Parts on Demand Tools: FDM and SLA

By: Joanna Carbajal

Ivaldi Group leverages cutting edge additive manufacturing and metal fabrication solutions to provide in-port parts on demand services for maritime and offshore industries. Drawing on a breadth of additive manufacturing industry experience, Ivaldi Group works across a range of stakeholders to digitize product portfolios and improve cost, risk and delivery for all parties. Some of our capabilities in FDM and SLA are discussed below.

FDM (Fused Deposition Modeling)

One of the additive manufacturing technologies that we currently use is FDM

(Fused Deposition Modeling). FDM fuses material layer by layer. This allows us to create parts with internal structures, cavities, shapes and geometries that are not feasible with a traditional manufacturing process.

Specifications for FDM technology:

Build dimensions: 305x305x305mm or 1 cubic foot  

Resolution height: Highest tested resolution is .1mm

Machine name: Type A Machines Series 1 Pro print pod - each print pod has 6 printers that allow us to print in parallel 

Materials for FDM:

Nylon is an impact and chemical resistant material 

Copolyester is a combination of different polyesters that are chemical resistant and durable. 

Polylactic Acid (PLA) is a strong, hard plastic 

Elastomeric is a rubber-like material that creates flexible parts 

SLA (Stereolithography)

Another additive manufacturing technology we utilize is SLA (stereolithography). SLA uses a laser to trace out printing paths layer by layer. Using heat and UV light, the parts are post cured to achieve full mechanical properties. We currently use Formlabs Form 2 machines for SLA technologies.

Specifications for SLA technology:

Build dimensions: 145mm x 145mm x 145mm

Resolution height: .025mm

Name of machine: Form 2 from Formlabs 

Materials for SLA:



High Temperature 


At Ivaldi Group, we are always looking for ways to improve our technology and capabilities. Ivaldi has developed methods to decrease print time and reduce cost per part using additive manufacturing so the maritime industry can obtain spare parts within 24 hours.
