FIELD OF THE INVENTION

The invention relates to methods for manufacturing articles from polymeric materials. The invention relates particularly to manufacturing water soluble articles from modified polyethylene glycol materials as a sequence of voxels.

BACKGROUND OF THE INVENTION

Manufacturing articles from polymeric materials is well known in the technological arts. Manufacturing articles as a presented sequence of volume elements (voxels) derived from a digital representation of an article is also well known. That some envisioned articles may have greater utility depending upon the extent to which at least portions of the respective articles are water soluble can be envisioned. Water soluble polymers are not generally dimensionally stable enough to enable the manufacturing of objects on a voxel-by- voxel basis without a material constraining mold or support structure. In addition to dimensional stability, the ability to adjust or tune the rate at which an article dissolves when in use, and the ability to process the material into an article at temperatures at or below the respective boiling points of carrier solvents such as water and alcohol, is also beneficial to preserve the nature of temperature sensitive benefit agents. What is needed is a polymeric material which is both dimensionally stable enough to enable the creation of objects by fabricating a series of voxels according to a digital representation of the desired object at temperatures which preserve the utility of benefit agents, as well as soluble in an aqueous environment to yield the desired advanced utility; and a method for manufacturing articles from such a material.

SUMMARY OF THE INVENTION

In one aspect, a method for manufacturing a three-dimensional object includes steps of:

a) providing a digital description of the object as a set of voxels; b) sequentially creating an actual set of voxels corresponding to the digital set of voxels; wherein at least one voxel comprises a composition comprising between about 35 and about 100 wt. % of a polymer selected from the group consisting of nonionic polyethylene glycol (PEG) homopolymers, PEG copolymers, and mixtures thereof; the polymer having an average molecular weight of between about 1,000 and about 95,000 AMU; and between about 0 and about 65 wt. % of a filler, wherein the filler is a solid at a temperature of above about 75 C, wherein the composition has a Melt Flow Index of between about 0.1 g/ 10 minutes and about 50 g/ 10 minutes when tested in accordance with ASTM D1238- 13 under a 1.2 kg load at 70 C using a half-die.

The composition comprising the polymer and the filler particles has a Melt Flow Index (MFI) of between about 0.1 g/ 10 minutes and about 50 g/ 10 minutes when tested in accordance with ASTM D 1238- 13 under a 1.2 kg load at 70 C using a half die. Composition having MFIs outside this range either fail to flow adequately at 70 C under a 1.2 kg load using a half die, preventing their use in creating the actual voxels, or fail to be sufficiently dimensionally stable upon being extruded, resulting in a voxel error of unacceptable magnitude.

Voxel error relates to any change in dimensional requirements of a voxel due to expansion, shrinkage or movement of the material disposed for a particular voxel from the dimensional limits of that voxel. Voxel error magnitude for any particular may be calculated as the volume percent of the voxel which is missing at the time that the last voxel of the overall translation which is adjacent to the particular voxel, is deposited.

Examples

Example 1 - Process for Making Polymer Blends

Mixtures are prepared by accurately weighing each component of the mixture into a glass jar at room temperature. The glass jars are capped and placed in an oven at a temperature above the melting temperature of the polymer and below the melting temperature of the filler (typical at 70 C), to the extent that the filler melts, for sufficient time to melt the polymer (typically two hours). The glass jars are removed from the oven and mixed to form a homogeneous blend. Any standard mixing technique that creates a homogeneous blend is sufficient. Examples of suitable mixing methods include stirring by hand with a spatula, overhead IKA mixers and a Flacktek SpeedMixer. Example mixtures are included in Tables 3 through 5 below where numbers represent printable mixtures and letters nonprintable mixtures.

Example 2 - Time to dissolve

Polymers and mixtures are melted by placing in an oven at a temperature above the melting temperature of the polymer and below the melting temperature of the filler. Typically samples are held at 70 C in sealed glass jars for 2 hours. The molten mixture is spread into triangular pyramid silicone molds where each triangular pyramid is symmetrical and 10 mm from base to opposite point. The mixture is cooled until solidified at room temperature. Each triangular pyramid is removed from the mold and weighed to ensure a weight of approximately 0.2 grams.

Time to dissolve is determined by placing a single triangular pyramid in a scintillation vial filled with approximately 20 grams of deionized water. The quiescent vial is backlit and imaged using time-lapse photography with one image taken every 30 seconds. The images are viewed sequentially as a movie at one frame per second. The time to dissolve is determined by eye as the time where the triangular pyramid is no longer visually apparent.

Example 3 - FDM Printing of Mixtures

Polymers and mixtures are stored in sealed glass jars in an oven at 70 C until fully molten. Molten polymer and mixtures are transferred into a syringe fitted to a FDM printer. The syringe is preheated and can be mechanically or pneumatically driven. Polymers and mixtures can be 3D printed using a Hyrel 3D System 30M printer fitted with a VOL-25 extruder print head with a 0.5 mm circular tip and a Quiet Storm cooling fan. The computer aided design (CAD) files of the part to print is digitally sliced to create a STL file and transferred to the Hyrel 3D printer. Print conditions including syringe temperature and pneumatic syringe pressure are optimized for each polymer and mixture.

Example 4 - Melt Flow Index The Melt Flow Indexes are determined in accordance with ASTM D 1238- 13 at 70 C using a half die and a 1.2 kg load. The half die has a smooth straight bore 1.048 +/- 0.005 mm in diameter and is 4.000 +/- 0.025 mm in length. The set temperature is 70 C and the maximum allowable variation in temperature is +/- 2 C measured 79 +/- 1 mm and +/- 0.2 C measured 14 mm +/- 1 mm above the die surface.

Example 5 - Measuring polymer molecular weight

The molecular weight of polyethylene glycol polymers and copolymers is measured using gel permeation chromatography with multi-angle light scattering and refractive index detectors (GPC- MALS/RI). Samples are prepared by dissolving 5 mg/ ml of polymer in an aqueous solution of 0.1 M NaN03 M NaN0 ₃ and 0.02 weight percent sodium azide buffer. Samples are passed through a 0.45 micron syringe filter and analyzed separately by aqueous GPC-MALS/RI using the following conditions: Waters HPLC, 0.1M NaN03/ 0.02 weight percent sodium azide moble phase, two Waters Ultrahydragel columns (200 and 250) in tandem, each column 300x7.5 mm, column temperature of 40 C, and inject 50 microliters of 5 mg/ml polymer solution using isocratic flow at 1 ml/ min. Polyethylene oxide standards available from Waters (24,000 Da to 850,000 Da) and Sigma (300 Da) are used for GPC calibration.

Data

Polymers suitable for melt rheology modification are described in Table 1. Polymers P2, P3 and P6 are printable without fillers. Polymer PI and P5 are not dimensionally stable enough to hold shape during solidification and this leads to unacceptable voxel error. Polymer P4 does not flow at 70 C preventing the formation of actual voxels.

Fillers are described in Table 2. The particles all have a melt temperature greater than 75 C or degrade before melting.

A level study of fillers mixed with PI is shown in Table 3. Polymer PI alone is dimensionally unstable and cannot be printed. Mixture A contains fumed silica (RM1) as a filler but remains dimensionally unstable to be printable. The MFI is 59 g/ 10 minutes. Mixtures 1 through 5 are dimensionally stable and flow sufficiently to be printed and have MFI ranging between 0.1 g/ 10 minutes and 27 g/ 10 minutes. Mixtures 1 through 5 contain two types of fillers (silica Fl and F2); however, different levels are required to be printable. Mixtures B and C cannot be printed because they do not flow in the printer at 70 C. The MFI is 0 g/ 10 minutes.

Table 4 contains examples of other mixtures that are printable and not printable. Here, the unprintable compositions have a MFI of 0 g/ 10 minutes. The printable compositions have a MFI ranging from 1.3 g/ 10 minutes to 22 g/ 10 minutes.

Mixtures 11 and 12 contain both a filler and perfume oil as a benefit agent. These mixtures are printable with MFI of 11 g/ 10 minutes and 2.8 g/ 10 minutes, respectively.

The time to dissolve for each mixture varies with both the type and amount of filler. Time to dissolve for Polymer PI is 1.6 hours (Table 1). Combining Polymer PI with 2 wt. % and 4 wt. % filler silica Fl reduces the time to dissolve (Mixtures A and 1, respectively). Mixtures 2 and 3 contain 6 wt. % and 8 wt. % of silica Fl but the time to dissolve is slower than Polymer PI alone. The same trend is observed for Mixtures 4 and 5 with Mixture 4 having a shorter time to dissolve and Mixture 5 having a longer time to dissolve than Polymer PI alone. Table 4 illustrates that the type and level of filler has an unpredictable effect on the time to dissolve. This is further complicated in the presence of a benefit agent like perfume oil as noted in Table 5.

Table 1: Polymers P1-P6 studied for mixtures and comparative examples CEl and CE2 that have a MFI that cannot be measured at 70 C because the polymer does not melt or flow. Molecular weight is measured using gel permetation chromatography.
