Rapid Prototyping
in medical
field
Continuous technological advancements in Rapid Prototyping technology ensure
success for all industries that require extreme precision and customization. In
particular, this technology has had significant results in the medical field, not only
for the realization of machines and surgical instruments, but also for the
manufacturing of orthopedic and dental implants, for the three-dimensional
reconstruction of skeletal structures or anatomical parts.
Medical equipmentCase for multi-use device
Material: Polyurethane resin
Technology: Vacuum Casting
The stereolithography technology is used to produce masters in silicone, as molds
for the realization of medical devices. The polyurethane resin is poured in the
molds, in order to obtain the final model. A subsequent finish with the metallization
can be applied to the device to realize aesthetic products.
Medical equipment
Hemodialisis machine
Material: Polyurethane resin
Technology: Vacuum Casting
Machines for hospitals, laboratories
and dental offices can be obtained with
Rapid Prototyping technologies. These
parts can be used in the preliminary
phase of the product development, to
conduct tests or to verify the correct
design of the piece.
Medical equipment
Medical pump
Material: PEEK
Technology: Selective Laser Sintering
(SLS)
SLS technology allow to reproduce 3D
printed models with high complexity.
Moreover, with this technology, it is
possible to use a material, like PEEK,
biocompatible, resistant to high
temperature and with high mechanical
properties.
Medical equipment
Breathing mask
Material: Polyurethane resin
Technology: Vacuum Casting
Silicone masters manufactured with
the stereolithography tecnology are
used as molds for the realization of
medical equipment.
The polyurethane resin, with a
hardness from 30 to 95 ShA, is poured
in the molds, in order to obtain the final
model.
Medical equipment
Oxygen bottle carrier
Material: Nylon
Technology: Selective Laser Sintering
(SLS)
Prototypes of emergency equipments
can be obtain with the Additive
Manufacturing technologies. The SLS
technology allows to product parts with
good mechanical properties, suitable
for mechanical tests.
Realistic anatomical model of organs or skeletal structures are reproduced starting
from DICOM images (CT or MRI). The 2D scans are elaborated to obtain an .stl file
of the 3D virtual model of the anatomical structures. This file is sent to the printer
for the realization of the 3D model.
2D scans2D sections of the
diagnostic images
are collected
Multi-slice CT scanThe patients are subjected
to CT or MRI clinical exam
Medical images processingThe scanner images are segmented
and elaborated in a medical images

3D model is created
3D printingThe .stl file is sent
to the 3D printer
3D printed modelThe printed-model

support material and
the 3D prototype is
obtained
Pre-surgical simulationThe 3D model is used by
physicians to plan and
simulate the surgery
Skeletal structures
Hand model
Materials: Trasparent rubber and rigid
material Simil ABS
Technology: Objet Polyjet
The 3D Objet Polyjet printing allows to
create plastic and rubber models with
different hardness, co-molded in a
single printing. All skeletal structures of
the human body can be manufactured,
starting from digital diagnostic images.
Skeletal structures
Femur model
Material: ABS
Technology: Fused Deposition
Modeling (FDM)
FDM and Sintering technologies allow
to create bone models, in 1:1 scale.
These can be useful for orthopaedic
clinicians to better study the bone
fractures and plan the surgery.
Skull model
Material: Polyamide
Technology: Selective Laser Sintering
(SLS)
3D printing technologies allow to
realize anatomic models of skulls,
which are used for:
• Maxillo-facial surgery;
• Plastic surgery;
• Trauma care.
Skeletal structures
Knee implant
Material: Cobalt Chrome super-alloy
Technology: Direct Metal Laser
Sintering (DMLS)
DMLS technology allows to
manufacture orthopaedic implants with
biocompatible materials, such as
Stainless Steel, Titanium and Cobalt
chrome alloys. Moreover, the capability
to produce customized devices with a
superficial structure which facilitates
the surrounding bone ingrowth is
important for a perfect integration of
implant with the patient natural bone.
Orthopedic implants
Odontoiatric implants
Odontoiatric model
Material: Vero White (high temperature)
Technology: Objet Polyjet
Dental laboratories around the world use
Rapid Prototyping, in particular the
Polyjet Objet 3D printer, to create highly
accurate models directly from digital files
acquired by means of oral examination.
The resulting 3D print prototype faithfully
reproduces the anatomy of the patient
allowing the clinician to quickly ascertain
the best information about the clinical
case, in turn facilitating the best plan of
action or any other type of application.
Heart model
Material: Tango Plus (Rubber)
Technology: Objet Polyjet
Scans derived from digital diagnostics
are processed to obtain .stl files of 3D
heart models. These files are input into
the 3D printer, for the realization of the
3D prototype. This prototype
reproduces faithfully the anatomy of
the organ. In this way, surgeons can
quickly acquire the desired information
on the clinical case, they can plan the
cardiovascular surgery and design
patient-specific implants.
Cardiovascular structures
Vascular and valves models
Material: Silicone, Tango Plus (Rubber)
Technology: Vacuum Casting, Objet
Polyjet
Prototypes of cardiac valves can be
realized to conduct experimental tests or
to design implantable patient-specific
valves. In addition, vascular models,
derived from CT images of a subject, can
be used for the hemodynamic analysis for
different vascular pathologies.
