Injection molding vs Pam technology
Brake Handle – HPP*
*High Performance Polyester
The first benefit of producing with a Pam factory is that firsts parts are avaible the day after design delivery. It allows to proceed to very quick quality tests and validate geometry and material of the part. Quality issues can be addressed very soon and design improvements are easy to implement.
With Pam technology, one brakle handle is printed in 4 hours with a printing profile using 0.4 mm nozzle and 0.2 mm layer height.
4 parts can be printed in a cycle of 12 hours per Pam system.
Regarding material cost, Pam technology is using the same material as injection moulding. A part will have the same material cost on both equipments.
We are considering the following datas:
- 35 $/hrs hourly rate;
- 3% defects rate 3% for both equipments;
- Effective working time of 10 minutes per cycle with Pam technology;
- Injection molding is working with one operators per cycle of 8 hours, 3 cycles are made per day.
As a result we determine that, with a Pam factory composed of 8 Pams systems, Pam technology is cost-effective up to 12 000 parts and is more producive than injection molding during the first 118 days after design delivery, which represent 7 600 parts.

Soft material demonstrator
The Pam technology is the first 3D printing technology able to transform very low hardness materials.
An octopus production was made internally on a New Pam Series P to demonstrate its capacities.
Used material: TPE TFOSTL (30 shore00)
Printing parameters: one extruder - 0.8 mm nozzle - 0.4 mm layer height - 25 minutes for 1 part
Production parameters: 5 parts per cycle - Transition between two production: 1 minute (parts removal and new printing cycle launch).
New Pam Series P is working 12 hours a day including 4 cycles per day and 1 cycle per night with no printing failure.
Availability rate = 94%
Performance rate = 99%
Quality = 100%
We observe an OEE (Overall Equipment Effectiveness) of 93% which demonstrates the reliability and robustness of Pam technology with a good machine setup.
To evaluate our capability we focus on part weight. Indeed with such soft material contact measurements are not efficient.
The input model used gives a weight of 10,8g per part. We are considering a tolerance of ± 5% so a part is acceptable between 10,3 to 11,3.
We weighed a population of 65 parts and obtained the distribution shown in the graphic (normal distribution). The normal distribution observed gives good results in capability:
Cp = 1,42
Cpk = 1,34
Orthopaedic Sole – TPU & PVA
The Orthopaedic Sole—here in a scaled down version— demonstrates capabilities of Additive Manufacturing for producing personalized goods for individuals. With its unequaled capabilities in treating elastomeres, Pam Series P can produce such parts with real hardness properties exploitable by professionals.
