17. Parts printed with DLS are much more like injection-molded parts.
DLS produces consistent and predictable mechanical properties,
creating parts that are smooth on the outside and solid on the
inside.
DIGITAL LIGHT SYNTHESIS: LAYERLESS INTERIOR
DLS results in layerless parts with consistent mechanical properties
CONVENTIONAL 3D PRINTING
Traditionally made 3D printed parts are notoriously inconsistent.
Their mechanical properties vary depending on the direction the
parts were printed due to the layer-by-layer approach.
18. Device Design Freedom
With complete design & manufacturing freedom
the possibilities are endless:
• Un-moldable design complexities
• Renewed concepts previously abandoned
due to manufacturing limitations
• Manufacturing to function not make-ability
The Un-moldable
19. “Smaller” Production Volumes
Production volumes make injection molding
costly and time intensive in getting going
Volume constraints removed:
• Patient matched items
• Device versions with limited numbers of
new parts in overall design
• Volumes in the 10s of 1000s vs millions
• Rapid device launches needed to
determine market opportunity

Part Consolidation
Additive process gives engineers freedom to
combine several features into a single part.
Assembly consolidation offers several
advantages including reducing:
• Points of failure
• Assembly time
• Hardware required to hold assembly
together
• Tooling

Good opportunity to educate customers process in layerless (if asked)
do not discretely cure one layer from another
I mentioned on the previous slide that our parts are layerless and these SEM images highlight that point.
What we’re looking at here is the interior fracture surface of printed parts.
On the left, you can see visible layer lines on the interior surface of a part printed by conventional layer-by-layer (SLA) 3D printing. These layers create brittle parts that are weak in one direction.
On the right, you can see that Carbon is able to produce monolithic structures that are solid on the inside
Why does this matter?
The adhesion between print layers may lead to much lower tensile strength in the build direction.
Many of you in the room know that a number of medical devices, like spinal cages, will experience complex in-vivo loading conditions that may exacerbate delamination/fatigue failures in additively manufactured parts.
It is important to have consistent mechanical properties.
Background:
Polymer systems can have as little as 15% of the tensile strength in the build direction (Ahnet al 2002)
A number of fatigue studies have been performed to investigate effect of build direction on fatigue strength
Carbon has tested nearly all of our commercially released resins for basic biocompatibility
Each of these materials pass cytotox, irritation, and sensitization
We are in the process of gathering biocompatibility data for our FPU, EPU, and soon-to-be-released Silicone material
Carbon is committed to understand the ability of our materials to safely be used in the low-volume production of medical devices.
Carbon has conducted a subset of the ISO 10993 biocompatibility tests on of a number of our resins
All of our commercially available resins meet the standards for non-cytotoxicity per the ISO 10993-5 MEM Elution test.
We have conducted irritation (ISO 10993-10 Intracutaneous Study) and sensitization (ISO 10993-10 GPMT) on a number of our materials. CE 220/221, RPU 61/70, EPX 81 and UMA 90 all are negative with regards to irritation and sensitization.
These test result are those that would allow for successful use of these materials in medical devices for short-term contact applications. The FDA will still require manufacturers to test the final device in accordance with these standards.
We plan to evaluate our other current resins and those on our roadmap for commercial release.
In April we announced the release of our M2 machine. This is our second commercially available machine.
It is a modern piece of industrial equipment with over two dozen on-board sensors that monitor everything from environmental conditions (temp, humidity) to build parameters (speed, light intensity), and a foot sensor that allows hands-free opening and closing the door.
