## What is Pikaslice?

Introducing Pikaslice, a comprehensive slicing solution for both Resin/MSLA and Filament/FFF 3D printers on the mobile platform. Effortlessly import your 3D models, adjust their orientation and layout, apply manual or automatic supports, examine your scene for islands, and export your work to an extensive range of supported Resin/MSLA and Filament/FFF 3D printers.

While the use of an Apple Pencil is highly recommended, it is not mandatory. To transfer the exported files to a thumb drive (and subsequently to your printer), you'll need an adapter, such as USB-C to USB-A, depending on your specific iPad and thumb drive model.

Please note that this app is compatible with a variety of resin MSLA, DLP, and FFF/Filament 3D printers (see the list within the app).

### 2/5 — Not worth the subscription

*2026-06-26*

There is zero justification to paying repeatedly for something like this.  The convenience of it being an app doesn’t change the fact that it gets stuck on export often, cant handle complex prints, and the docs refer to an auto support generation method that is not present in the app.  No one wants to drag around and place supports for every single print.  The AI features are a useless novelty marketing gimmick as it applies useless changes that dont even take effect.  Hard pass.

**Developer response:** I'm sorry the app didn't live up to your expectations. The export issue definitely isn't the experience I'm aiming for, and if you're able to email me with your device model and the file that gets stuck, I'd like to investigate. Complex models are supported, but performance does depend quite a bit on the device's available memory and processing power, so there are cases where older or lower-memory devices can struggle. I'm also curious about the auto support feature you mentioned. If the documentation refers to a support generation method that you couldn't find in the app, please let me know which page or section you saw - that may be outdated documentation on my end, and I'd like to fix it. The same goes for the AI features. If you can tell me which ones you tried and what changes didn't take effect, that would help me determine whether it's a bug or something that isn't working as intended.

### 3/5 — Limited but usable

*2026-03-15*

Can you make Gcodes? Yes. Can you edit STL files? No. Is it glitchy? Yes. Does it freeze and crash periodically? Yes. Your ability to set layer temps is nonexistent and the infill patterns are limited to 3 options. The process of editing supports is very tedious and requires practice to make it less annoying. Beware that the “autosave” isn’t really saving your work in the event of a crash…you will have to start over. Same goes for when the app freezes and you have to close the app and reopen it. It’s currently the only slicer I’m using on my iPad Pro but if the devs don’t make some tweaks that could very well change. That being said; the apps mostly works and you can get the job done with plenty of patience.

**Developer response:** Thanks for the honest review. Just to clarify one point - layer temperatures can be set for the first layer and for all subsequent layers. On supports, I’m not entirely sure which mode you were using - there are four options for filament printing (auto-generated at slice time, manual supports, block supports, and graph supports), and the experience can vary quite a bit between them. If you were using manual supports, that workflow is admittedly more hands-on right now and can feel tedious, which is something I want to refine. STL editing is currently limited to separating shells and planar cuts, so it’s not intended to be a full modeling tool. Crashes and freezes definitely aren’t expected, so if you can share anything reproducible (file, steps, what happened right before), that would really help track it down. On infill, additional patterns were already in progress and will be included in the next update (including honeycomb and gyroid). Appreciate the detailed feedback.

### 1/5 — RIP off

*2026-01-23, version 4.2.1*

WHY DO YOU NEED A SUBSCRIPTION TO MAKE A .GCODE FILE! ALSO IT ONLY SUPPORTS 3 PRINTERS WITH FLASHFORGE!

### 1/5 — Supports every single 3-D printer from my brand except mine

*2026-01-11, version 4.2.1*

It supports every single geek, tech, 3-D printer except the M1 like are you serious for me right now?

### 3/5 — Review

*2026-01-02, version 4.2.1*

It’s okay as a slicer, but don’t trust the print time estimate, because it is usually wrong.

### 5/5 — No auto support

*2025-12-27*

It’s a great app don’t get me wrong but I’m new I’ve ask the ai chat bot what to do and it won’t work. I did everything it said but I can’t find the auto support setting. It is probably just me but I can’t find it.

### 1/5 — Austin

*2025-11-29, version 4.1.1*

Horrible app. Paid for 1 year and it doesn’t even work. I have a 3d printer and all I got the app for was slicing objects but it doesn’t do it properly. I did a test and it just puddled filament in a few spots didn’t do any layers. It said you got 1 free trial day and I canceled my subscription within hours and still haven’t seen the money come back to my account. This app was such a waste of money. Please don’t waste your time or money on it.

### 4/5 — Make it free

*2025-11-25, version 4.1.1*

Make it free then every one will download the app more

### 1/5 — Not free/ not good for filament

*2025-11-08, version 4.1.1*

Make it a one time payment and I might deal with the headache. Doing supports for printing filament is a pain with this, I hate that it’s the only one available on iPad

### 1/5 — Couldn’t get it to work

*2025-11-08, version 4.1.1*

First impressions looked great, hundreds of machines supported. Opened a file ok, rotated and set up on the bed just fine. Then it went wrong. Froze every time I tried to add graph support, so ended up having to use block support, then when I tried to slice the file it constantly froze again. 

Gave up and got my laptop out, I was just being lazy.

### 4.5.0 — 2026-06-03

CHANGELOG

Version 4.5.0 brings a redesigned phone experience, clearer filament setup, safer multi-material export, new printer profiles, and broad slicing, export, and stability improvements.

Highlights

Phone interface
- The app now switches to a phone-optimized interface when running on phones.
- Opening and saving scenes, onboarding, machine selection, printer settings, feedback, slicing, progress, sliced file preview, documentation, tutorials, and post-export views now have small-screen layouts.
- Bottom sheets, larger touch targets, round buttons, phone-specific sliders, better side-menu behavior, and improved portrait and landscape handling make the phone UI easier to use.
- Many dialogs and popups were also tuned for smaller screens.

Filament materials and print processes
- Filament settings are now split into separate material and process profiles, making it easier to tell which settings describe the filament and which describe the print.
- Process profiles support names, reset actions, compatible nozzle diameters, clearer categories, and better integration in printer and material configuration views.
- Default machines now include material and process profiles, giving new printer setups better starting points.

Multi-material setup and export
- Multi-material workflows now track swatches, physical tool slots, nozzle sizes, selected processes, and assigned materials more reliably.
- These assignments are saved in app settings and scenes, so printer setup is preserved across sessions.
- The app now warns about unresolved used channels and blocks slicing or export until each used channel has an assigned tool and material.

Plate, color, paint, and preview workflows
- Multi-plate export handling was improved, with per-plate selection state used in resin and filament slicing/export flows.
- Color swatches are more consistent across material selectors, color picker presets, material slots, and paint workflows.
- Paint channels can be saved as swatches and then bound to physical tool slots, making color planning more flexible.

Printer support
- Added profiles for Qidi Max 4, Qidi Q2, Qidi Q2C, Anycubic Kobra 3 V2, Anycubic Kobra 3 Max, Anycubic Kobra S1 Max, Anycubic Kobra X, Anycubic Kobra 4 and PioCreat Halot X1.
- Material-change G-code support was improved for Anycubic Kobra 3 Combo and the Centauri Carbon profile with upgrade kit.
- The Sovol S08 profile name was corrected to SV08, and printer thumbnails were improved.

Slicing, export, and generation tools
- G-code export now handles additional placeholders, preserves material metadata more reliably, and avoids problematic standalone tool-change codes.
- Wipe tower planning was improved with flushing volumes, prime-tower purge mode, fallback settings, and better positioning.
- Generated mesh and drawing tools received fixes for model selection, undo/redo behavior, payment overlays, credit display, panel binding, and crash handling when a user has no credits.

Additional improvements
- Added default PLA and PETG materials for 0.2 mm, 0.6 mm, and 0.8 mm nozzles.
- Added G-code placeholders for current_extruder, initial_layer_print_height, and outer_wall_volumetric_speed.
- Fixed CXDLP4 R009 layer decoding, flow calibration per-part overrides, and crashes related to resin machines without defaults, queue image requests, stale transform selections after export, and no-credit mesh generation.
- Improved notifications, feedback submission, machine search, recent filename display, documentation, tutorial tiles, onboarding, dark theme styling, buttons, popups, material combo boxes, and editable G-code fields.
