IDENTIFY PRINT QUALITY OR SUB-SYSTEM DEGRADATION ISSUES FOR 3D PRINTERS USING LAYER TIME ANALYSIS
One of the core concepts in additive manufacturing is to have accurate powder deposition on bed
with uniform duration throughout the print job. The inaccuracy in job layer duration arising when
some layers take more or lesser than the recommended value, often results in bad part quality issue
or indicate issues with print hardware components.
This disclosure describes a method for improving Print Quality (PQ) and reduce unplanned
downtime (due to sub-system failure) by looking at layer time for the print cycles and figuring if
they are running off the prescribed limits for the material used. Based on this information the
erroneous machines can be inspected for diagnosing fault. Analysis by services and support (using
the information from the cases flagged using this technique) suggests the dominating cause to be
hard drive failures (replacing which solves the problem), though there can be other reasons as well
HIGH CAPACITY INK COLLECTOR FOR TEXTILE PRINTING ON POROUS MEDIAS BASED ON SLOPING PLATES
Textile printing, and specifically digital textile printing is becoming more important in the industry
the last years mostly because of the improvement in the versatility, customization and time
reduction between first designs and the introduction to the market. In some application (e.g. dye
sublimation) the workflow requires to print in some paper media and transfer the ink to the textiles
by means of a calender (external machine). On the other hand, in some other applications, direct
printing ( Direct To Fabric or DTF) on the textile media is possible (e.g. fashion, decor, some soft
signage). In some of these DTF applications (e.g. flags), the media used to print on is porous. Thus,
printers must be able to collect and manage the rest of ink that pass through the media
A TBT eGFX MONITOR TOPOLOGY, WHICH ABLE TO SUPPORT OPTIONAL eGFX CARD BE AND SUPPORT BASIC DISPLAY FUNCTION WITH SAME USB TYPE-C CONNECTOR WHEN CONNECTING NON-TBT HOST
Enterprise customer requires to join a lot of meeting and take the notebook back to home to continuous some light
loaded working, but some of customer requires drawing/reviewing CAD which requires external graphic card to
support working smoothly. Intel TBT technology allows TBT NB connects external Graphic Card in TBT docking, so
to be an TBT eGFX monitor can make user to have better graphic performance for CAD usage even use light
notebooks
I2C BASED SECURITY INK SUPPLY SMART-CHIP RECOGNITION
In Thermal Ink printers, Ink supplies include a security chip to properly identify the supplies and control
the remaining ink quantity. This security smart chip is owned by each brand and optimized to ensure the
robustness in front hacker attacks and counterfeiting.
Smart-chip communication with the host printer uses I2C serial bus protocol which is a wide spread
industry standard. HP latest device revision includes new functionality beyond the I2C protocol which
helps the printer in trying to recognize if the smart-chip is original. The printer sends a command to the
smart-chip, which in response pulls down the I2C data line during a certain time; an HP original chip is
expected to respond precisely, meeting the time interval.
Enabling the ability of doing time measurements on the I2C data line typically requires extra Hardware
resources and the redesign of the existing electronics. Such modification takes time to design and
complete the validation of the new hardware and can lead to cost increments.
The implementation presented enables the capacity to send the I2C commands, check if the smart-chip
pulls down the data line and the certain time measurement only with the I2C serial bus dedicated pins.
Not adding more resources and without changing the PCA design

EXTERNAL HEATING DEVICE TO FACILITATE UNPACKING PROCESS IN POWDER PROCESSING STATION
This disclosure relates to the field of 3D Printing with Thermoplastic Polyurethane (TPU) material. The
process to print parts using this material has very strict timing constraints.
An accessory is disclosed that provides the user more flexibility by preventing the loss of temperature
during the unpack process, leading to enhanced part quality. The system described can be assembled on
the processing station and used during the unpack of TPU parts

HALOGEN LAMPS CONNECTION SYSTEM
Some printers are designed to print 3D plastic parts. Some of the advantages that such printers
provide are: ease of use, clean solution, good price/performance, good reliability, and high
productivity.
Some 3D printers use a pair of halogen lamp-based energy sources: a first source on the top
of the printer composed of an array of lamps and used to maintain certain temperature on the
printing zone (close to melting point), and a second source placed on the print carriage that
applies the extra energy to fuse and melt the selected powder. This last system is called the
fusing module
BLOCKOUT GENERATION FOR 5 LAYERS SANDWICH PRINTMODE
Sandwich application is commonly used in the windows graphics market, but it can be very attractive for
other applications done with transparent media (flexible or rigid). It consists on printing an image A, then on
top of it a white layer and finally on top of the white layer and image B (which could be the same as A if
desired). Thus, images A is visible from one side of the media and B is visible from the other side of the
media. One of the main challenges to obtain a good sandwich output is the opacity provided by the white
layer between the color layers because if this layer is not enough opaque one image might be seen mixed
with the other image and you donât want this effect. It is not a matter of quantity of white. Obviously if you
put 4 drops of white the opacity will be higher than when you put only 2, but there is a point of saturation
of our ink and the opacity doesnât change although you put more ink. This limitation (or saturation point) is
not specific to latex but also present in competitors as UV inks. To solve this problem a layer of black color
can be added as following: print image A, white layer, black layer, white layer and image B in this order. This
black layer prevents transparency between sides and provides full opacity.
Some UV competitors already have a 5-layer sandwich solution among their features. In order to close this
competitive gap, a 5 layers mode was strongly required for the latex R-series but the current pipeline was
not able to handle such a high number of planes. In order to overcome this technical limitation, the proposed
invention reuses the information of some of the planes to map it, after some smart masking
implementation, to the proper colorant trenches of the printhead to finally generate a 5-layer sandwich
mode printmode
