Using 2.5pm mask filters to clear IPA?

Onno — Thu, 07 Dec 2023 14:37:52 +0000

I was wondering if anyone had considered using 2.5pm mask filters to clear the resin residue out of IPA. These filters are very cheap, now that the pandemic is over. I already saw a filter based on a face mask, but that one has a curvature to it, while the panels of the 2.5pm mask filters are flat.

Is this a viable idea?

Using Screen for displaying PCBs

Danel Miarka — Mon, 17 Jul 2023 06:22:12 +0000

Hi, I have already read an article about creating PCBs with Prusa SL1s and it's great, works good on our SL1. In our lab, we would want to elevate this to a level where a touch screen on Prusa SL1 would show you black and white representation of PCB which you placed inside. I am worried that it would take a software changes and since we are material lab, we are not so coding savy. Has anyone tried this idea before ? If so, how'd it went ?

Smooth print platform surface? (for printing transparent microfluidics plates flat)

am-erik-a — Thu, 29 Jun 2023 09:52:47 +0000

I am printing some microfluidics chips (plates) with transparent materials. A typical plate is 50 mm x 35 mm and the thickness can be 1.5 mm. One side is structured and one is unstructured. I print these plates flat. The unstructured side of the print gets the surface roughness of the print platform. This causes haze. I see that some have glued a glass plate to their platform in order to get a printed plate with a smooth bottom surface (https://www.moiin-resins.com/wp-content/uploads/2023/04/A-case-study-of-MOIIN-resins-for-cell-culture-device-fabrication-final.pdf). I'm tempted to try this, or just polish the aluminium platform. Of course, the adhesion of the print to the platform will be an issue, but an adhesion promoter (e.g. https://monocure3d.com/collections/platebond) may help. Which material will give the best adhesion; aluminium or glass?

Do you have any thoughts or experience regarding such a smoothened platform?

Making PCB's on SL1S

ejberg — Sat, 20 Nov 2021 17:01:04 +0000

With the higher UV output and monochrome screen of the SL1S, a thought hit me last week: Maybe it is possible to use it for exposing photosensitized printed circuit boards directly. Today I tested it, and it looks very promising.

Here is my calibration test. The handwritten numbers are the exposure time in seconds. The built-in resin calibration function was used, but it can't write the exposure time when only "printing" one layer.

4 mil tracks (0.1 mm) are too small. 6 mil tracks looks possible if the pcb is exposed, developed and etched carefully. 8 mil tracks are no problem.

I need to experiment some more, but this looks promising.

BOFA PrintPro 1 Filter System

star_wyvern — Thu, 07 Oct 2021 23:03:01 +0000

Hello,

I just bought a BOFA PrintPro 1 for my SL1. I followed the directions and printed this 40MM Adapter, removed the existing filter.

https://www.prusaprinters.org/prints/5199-filter-hose-adapter-for-sl1

My question is - How do I keep the filter fan and replace the metal front piece to replace with the printed adapter?

It seems that the fan is glued in on both sides.

Thanks!

Slanted Build Plate.... But CNC!

Hey all!

This doesn't seem to be as popular a forum as the MK3, but I figured I could share here as well.

I took the CNC'd build plate files from Prusa's Github page, and modified them to add ramps to each side! Now the resin just drips off as the plate rises.

I'm lucky enough to have access to a CNC shop so I had this made and anodized.

I've attached the Inventor file if anyone else wants to take a swing at making one! Its worked very very well so far.

Attachment removed

Flex plates for DLP/(M)SLA

Too bad, that this will not work on the Prusa SL1. 😅

385nm for SL1?

Studio Robbe — Thu, 12 Mar 2020 14:42:12 +0000

Hi all,

I bought the SL1 printer for prototyping purpose.
Yet i found there are interesting resins produced by suppliers as DETAX (water soluble / silicon casting material ect.)
https://www.detax.de/en/content/3D-Produkte.php
These materials are developed for printers such as the ASIGA brand.
The biggest difference with these high grade printers is the use of 385nm and their price 🙂
Would there be a way to replace the LED module of the SL1 from a 405nm LED matrix to a 385nm Matrix?

Are there other people who would also like a 385nm mod aswell?

Greetings!

SL1 compatibility with special resin

s.schmid — Mon, 20 Jan 2020 14:51:14 +0000

Hi,

im about to buy a SL1 and i want to mix my resin with a kind of stonepowder and other incredients for special effects on the prints.

Do you think this may be a problem for the FEP-sheet or the printer itself? Could anything go wrong?

I had an testjob by my friend on an anycubic photon and it was not so bad. So wenn a 400 printer can handle ist, a Prusa should just handle ist very easy.

Would love to hear your thoughts about this.

Status info via API or USB

Eyn Ergy — Tue, 07 Jan 2020 18:15:14 +0000

It would be nice to have some kind of status info or live stream of events.

I explain for example if I want to create nice timelapses it would be perfect to trigger the camera always at the same point (the vat angled for example).

Having a stream of events from API or USB communication would help to script a camera trigger.

I see lot of other possibilities like chaining events from end of print, communicating errors,...

I will look at the source code to see what can be done but would be better if it comes from Prusa direct ;-)
