Our PCL (Polycaprolactone) 3D filament is a very unique material that can well suited for many unusual applications.

PCL is also a safe & biodegradable plastic!

The main feature of PCL is that it has a very low melting temperature compared to usual 3D printing materials such as PLA, ABS etc.

Main Features of our PCL filament:

• PCL has a melting temperature of only 58°C ~ 60°C.
• It can be 3D printed at much lower and safer temperatures (70°C to 140°C) and does not require a heated bed.
• Objects can be re-shaped after printing to fit specific application by simply softening it in warm 60°C water (Example: re-shaping a river to fit through a whole).
• Once cooled, PCL is a very tough and impact resistant plastic.
• PCL has a glass transition temperature of -60°C which makes it tough, flexible and durable.
• Can be easily colored
• Great inter-layer adhesion

NET WEIGHT: 1 KG (2. 2 LB)

3D printing with low-temperature plastic

4 shows the external parameters that affect the course of the extrusion process. At the same time, thermophysical transformations take place in the material itself, leading to a change in the physical state of the polymer material. Extrusion 3D printing, as well as traditional methods of processing polymer materials, is based on the transfer of a polymer material into a viscous state (melt). nine0005

One of the key parameters of extrusion 3D printing is temperature: printing (heating block) temperature, working platform temperature, ambient temperature. The conditions of extrusion 3D printing are not isothermal even if the 3D printer has a passive or active thermal chamber. In [7], the temperature distribution in the 3D printing area was experimentally measured, showing its non-uniformity ( Fig. 5 ).

, glassy, ​​viscoelastic. One of the methods for analyzing thermophysical properties is differential scanning calorimetry (DSC; GOST R 55134–2012 (ISO 11357–1:2009), which consists in determining the difference in heat fluxes as a function of temperature and/or time in the process of exposure to the test and reference samples by a controlled temperature program. Heat fluxes are supplied to the crucible, inside which the test and reference samples are located. DSC analysis makes it possible to investigate physical transformations (glass transition, melting, crystallization, polymorphic transformations), in particular, in thermoplastic materials.

For thermoplastic wax, an example of a thermogram obtained as a result of DSC analysis is shown in fig. 6; for plastic type TPU with a hardness of 55D - at fig. 7.

Fig. Fig. 6. Thermogram of thermoplastic wax

Fig. 7. Thermogram of thermoplastic TPU type plastic with a hardness of Shore 55D

at a temperature above the glass transition temperature and up to a temperature of ~120.0°C, the thermoplastic material gradually passes into the melt state. nine0005

The temperature maxima on the thermogram are associated with the melting of crystallites of different sizes. The temperature range of 3D printing is selected from the range of values ​​from 90 to 115°C, which is due to the completion of the transition of the polymer material to the melt state. The boundary (minimum and maximum temperatures) is selected depending on the material properties of the product, for example, the mechanical properties that must be formed as a result of processing. Verification of mechanical properties can be performed on the basis of a tensile test of standard samples (GOST 11262–2017 and GOST 33693–2015 (ISO 20753:2008)).

From the thermogram of plastic type TPU ( fig. 7 ) the glass transition temperature (according to the second heating; Tst) is determined - 18.97°C. The temperature range of 3D printing is selected from the range of values ​​from 190 to 205°C, which is due to the completion of the transition of the polymer material to the melt state. The boundary (minimum and maximum temperatures) is chosen in the same way as in the case of thermoplastic wax, depending on the material properties of the product, for example, mechanical properties that need to be formed as a result of 3D printing. nine0005

Conclusions and forecast

The performed analysis of the literature, conducted full-scale experiments allow us to formulate recommendations on the choice of temperature range for extrusion 3D printing of some low-temperature thermoplastic plastics: mechanical), which must be formed in the material as a result of processing; nine0005

- a preliminary selection of the temperature range can be predicted from the results of DSC analysis - a thermogram; clarification of the temperature range - based on the results of a study of the achieved level of physical and mechanical properties required in accordance with the operational requirements for the product;

— Extrusion 3D printing temperature calculated from thermogram requires additional verification (confirmation) from test results, such as tensile testing. ■

Polycaprolactone (PCL). Monofilament launches PCL monofilament for 3D printing

Currently, there is a growing interest in the production of biocompatible plastics for the creation of long-acting implants using additive technologies. Implant sizes are always different for different human vessels or bones and require a custom design. It is difficult for traditional processing methods such as injection molding or injection molding to compete with additive technologies due to their long production cycles and the high cost of molding tooling for product development. nine0005

Fig. 1. Polycaprolactone implants

A number of materials have been identified that have the ability to be biocompatible, such as polylactic acid, polyvinyl alcohol and polycaprolactone (PCL, Polymorphus), but have different properties and behavior. The last of these, PCL, is a semi-crystalline and hydrophobic biopolymer that prevents accidental hydrolytic cleavage of the ester chain and, as a result, degrades over a relatively long period compared to other bioresorbable polymers. This is of great interest for 3D printing of biocompatible elements and products with a long service life, especially where structural support is required for many weeks. nine0005

PCL also decomposes under physiological conditions at certain times (depending on the molecular weight of PCL) into components that are safe for the human body, which was the main reason for using it as an implantable biomaterial. PCL is used as a suture and implantable biomaterial, as a capsule shell for drugs, and in cosmetology as a filler for local injections.

PCL has also been widely used in the manufacture of clothing and footwear, various layouts and food containers because this material has good elasticity and high strength. When used in modeling, it easily takes the desired shape, and can be molded from it as if from plasticine. PCL is often used as a material for making crafts, custom fasteners, or other parts. But it is not suitable for creating functional mechanical models. nine0005

Polycaprolactone is a quality, biocompatible and biodegradable polyester plastic derived from petrochemical raw materials. Has a low melting point 59-64 ⁰ C.

2. Structural formula PCL Softens in warm water, after which it becomes transparent and plastic. Rice. 3. Polycaprolactone granule and its softened appearance in warm water

The biodegradability of this plastic lies in the fact that under the influence of environmental factors (ultraviolet radiation, exposure to microorganisms, high temperatures and radiation), the material is completely decomposed into carbon dioxide and water , with partial - to the formation of methane, hydrocarbons, carbohydrates or inorganic mixtures, as well as intermediate metabolic products in living cells.
